Most of the distorted markers were clustered together and all the markers on LG8 were highly distorted markers. Two domesticated forms of zombi pea are cultivated as crop plants; seed and tuber forms. ), oilseeds (rapeseed mustard, sesame, groundnut, etc. This indicated wild germplasm having small tuber have potential to increase yield of large tuber cultivated type. Using field observation and pollinator exclusion treatments, i.e. Red and orange gave significantly greater growth of seedlings. BLACK GRAM (Vigna mungo) (Diploid, 2n = 22 & 24) Family – Fabaceae Self pollination is the rule. When they are pre-zygotic, the use of growth regulators during pollination is recommended. Five QTLs for tuber width and three QTLs for tuber weight. No. Pollination requirements for several crops. Pollinated pistils were treated with gibberellic acid (GA3) (70 p.p.m.) Often called green gram or golden, it is cultivated in several countries of Asia, Africa, and the Americas. Electric stimulation also caused the fusion between organelles. Pulses: Redgram and Bengal gram, Green gram, Black gram and Cowpea; Soybean, Horse gram and Lab-lab. Creation of variability through pollination and artificial hybridization is very difficult as the flowers are cleistogamous. Overall, it was found that desirable traits such as high pod number, seed weight, productivity and resistance to diseases have been introgressed successfully into black gram from ricebean. Most of the distorted markers were clustered together and all the markers on LG8 were highly distorted markers. All rights reserved. Growth and lethality of the interspecific hybrid seedlings were influenced by the genotypes of both parental species. of gamma rays and multiplied on the same medium. Thus, the results suggest that in black gram Mo was variably mobile, being phloem immobile at low Mo supply, but phloem-mobile in all plant parts with the possible exception of stem segments at adequate Mo supply. Mungbean Symp., Asian Vegetable Res. ii. Twenty-four uniform progenies, bulked in F7, were evaluated for yield potential. Main improved attributes of mutant variety are early maturity, errect, photosensitive and determinate type. Valued for their grains with high and easily digestible proteins, these crops are also known as forage, green manure, and cover crops. and Devel. Pollen parents were homozygous dominant for a different one of the three marker genes. One of these seeds germinated and a partly fertile interspecific hybrid was obtained. 1999; Hee et al. Flowers could be produced in culture about 5-6 months after seed sowing by appropriate, The morphology of flowering of several cultivars of Dioscorea rotundata , Poir is described. The flower opens in the morning at 7 am. Mature seed colors can be yellow, brown, mottled black or green, depending upon variety. We found the hybrid acquired vigorous growth from V. umbellata and drought tolerance plus early flowering from V. exilis, and thus has taken over some habitats of V. exilis in limestone karsts. (1982) L. orientalis × L. tomentosus Ladizinsky and Abbo (1993), van Oss et al. In contrast, in reverse crosses, seeds are totally or partially empty and fail to grow. Large-effect QTLs (PVE > 20%) were on LG4 (pod length), LG5 (leaf size and seed thickness), and LG7 (for seed-related traits). Iriawati, H. M., T. Taniguchi, and Y. Takeoka, 1996: Ultrastructural studies on the fusion product between protoplasts of mung bean and adjuki bean. Can I return more than the $300/acre? These studies and some other studies (Singh and Bains 2006) indicated that stable and high degree of resistance to MYMV and some other desirable traits could also be successfully incorporated into black gram from ricebean. A remarkable increase in viable seed production was found for the interspecific cross,V. Comparing this V. vexillata linkage map with a previous linkage map of V. vexillata and linkage maps of other four Vigna species demonstrated several macro translocations in V. vexillata. 29 Likes, 0 Comments - Alderville Black Oak Savanna (@aldervilleblackoaksavanna) on Instagram: “Yesterday this Tiger Swallowtail butterfly knew it was butterfly day for pollination week! If you do not receive an email within 10 minutes, your email address may not be registered, Although seed productivity was not different between reciprocal crossings, number of mature seeds, seed germination percentage and number of seedlings acquired were significantly higher when A. mangium was used as the female adult and also varied greatly among cross combinations. 80 days — 'Black Beauty' is the classic, garden standard for eggplants and commonly seen at farmer's markets and on produce stands. In a breeding program for incorporating cyst-nernatode resistance of the green gram into the adzuki bean, an interspecific cross between a cultivar of the green gram and a semi-wild relatrve of the adzuki bean, in endemic name “Bakaso” was made recrprocally. All the progenies were found resistant to Mungbean yellow mosaic virus, Cercospora leaf spot and Bacterial leaf spot diseases. Except for the cross between V. umbellata and V. angularis, all other reciprocal interspecific crosses were unsuccessful. 14 No. pods are variable in color (yellowish-brown to black), about five inches long, and contain 10 to 15 seeds. Large-effect QTLs (PVE > 20%) were on LG4 (pod length), LG5 (leaf size and seed thickness), and LG7 (for seed-related traits). In this paper, we further report our experience with in vitro flowering of Dendrobium Chao Praya Smile as a model system and discuss the usefulness of in vitro flowering and in vitro pollination for the orchid industry. Seedling development is described from seed germination to the establishment of several leaves on the seedling. Seed productivity was also low on the intraspecific pollination of A. auriculiformis. Rich., incompatibilities occur between pollen and stigma on one hand, and between pollen and style on the other hand (Kouadio et al., 2006) the case is similar during hybridizations within potato group (Jansky, 2006). Ohwi and Ohashi) ]. Given the wide crossability of V. umbellata, the hybrid can be a valuable genetic resource to improve drought tolerance of some domesticated species. Using one of the hybrids, Dendrobium Chao Praya Smile, as a model system, methods for in vitro flowering and in vitro pollination are described. However, chloroplasts from mung bean and proplastids and ER fragments derived from adzuki bean were still encountered on their initial sides. In assessing the effectiveness of pollinator guild on seed viability, we found no differences in percentage seed viability, seed germination or seedling emergence between exclusion treatments. Furthermore, a successful interspecific hybrid of V. mungo x V. angularis was accomplished through the use of intraspecific hybrid parents. The grains are hard and firm. The pollen germination, Access scientific knowledge from anywhere. 1) Autogamy or self pollination and 2) Allogamy or cross pollination. Seedlings were obtained at a low percentage (0.76%), and the We grew Kali Black Gram for the first time as a means to increase diversity of our plant-based pantry-friendly protein sources. Black gram : Country: India : Description: The mutant variety Co 4 was officialy approved in 1978. Interspecific hybridization of food legumes by conventional methods of plant breeding. Percentage fruit set and seed germination were similar for all pollination sequences. Learn about our remote access options, Department of Plant Breeding and Genetics, Himachal Pradesh Agricultural University, Palampur 176 062 (HP), India. Genus Vigna comprise several domesticated species including cowpea and mungbean, and diverse wild species. Due to the long juvenile phase of orchids, the entire breeding cycle could be 3 to 5 years depending on the genotypes involved (Kamemoto et al. Self-pollination occurs so insect and wind are not required. It belongs to the family leguminosae and subfamily papilionaceae. Grams are native crops of India. Apricot: All varieties are self-fruitful but cross pollination is helpful. Cleistogamy has been reported in some varieties of wheat, barley, oats and several other grass species. To read the full-text of this research, you can request a copy directly from the authors. Anther position. The best stage to harvest pearl millet is when the plants reach physiological maturity determined by the black spot at the bottom of the grain in the hilar region. treatment with benzyladenine (BA). These findings highlight the importance of pollination by opportunistic avian nectarivores in Aloe. Sow black gram and green manure plant kolunchi or purple tephrosia (Tephrosia purpurea) together at the time of harvesting paddy. Genetics of domestication have been investigated in most of cultivated Vigna crops by means of quantitative trait locus (QTL) mapping. Number of QTLs detected in each trait ranged from 1 to 5 with an average of only 2.3. Will this be a bad PFA year? 1st Int. Floriculture and Ornamental Biotechnology. The effort, time, labor and capital investment in orchid breeding is tremendous and in most cases, only a few elite plants with desired characteristics are selected among the thousands of seedlings germinated from a seedpod. With better understanding of the processes behind pollen germination and pollen tube growth, fertilization, embryo and endosperm development and inheritance pattern, strategies have been developed to avoid pre- and post-fertilization barriers in successful distant hybridization leading to alien gene transfer. 2007; Sim et al. For genetic improvement of cultivated vignas, mainly cultivated germplasm and exotic lines have been used so far. Crossability was very poor in black gram × ricebean crosses, and only two to nine true hybrid plants were obtained. Field Crops. Sci. 1991, Verma and Brar 1996. The methods of embryo rescues facilitate the interspecific crosses and contribute to exploiting the available genetic diversity within plant germplasm. Purple tephrosia seeds take longer time as their seed coat is very hard. Nevertheless, alien gene transfer through genetic transformation and use of molecular breeding tools still lag behind in Vigna and therefore need special attention. This is the common form of out-breeding. A true‐breeding black gram (Vigna mungo) × green gram (Vigna radiata) derivative was reciprocally crossed with adzuki bean, Vigna angularis. Its hybridity was confirmed at the seedling stage based on the presence of the green epicotyl colour of the adzuki bean. (1995), Fiala (2006), L. culinaris × L. lamottei Fiala (2006) L. culinaris × L. nigricans Cohen et al. The relevance of these results for the development of plant tests for … In Vigna species, early generation (F 1 and F 2 ) hybrid progenies derived from hybridization of distantly-related genotypes always possesses pods with incomplete filled (empty seeds in some locules) [49. Introduction Conventional orchid breeding is a lengthy process. ( 1987 ) Growth regulators V. radiata × V. umbellata, ... V. radiata × V. mungo Avenido et al. Number of times cited according to CrossRef: QTL analysis of domestication syndrome in zombi pea (Vigna vexillata), an underutilized legume crop. Parental genotypes also affected the fertility of interspecific hybrids. As a result, the duration required for breeding program could be shortened and tremendous cost could be saved. The original floral colour of 'Snow Ball' is white with flat and incurving florets. The fusion product started to divide after 5 days in culture. The pollen grains are sticky and cannot be dispersed by wind; small insects are probably the main agents of pollination. Category. 2007). Mungbean Symp., Asian Vegetable Res. The flower opens in the morning at 7 am. (1984), L. orientalis × L. odemensis Ladizinsky et al. Production of hybrid plants is feasible if filled seeds are selected and germinated following the end of seed dormancy. Examples – legumes like pea, gram, black gram, soybean etc. . Colours of epicotyl and stem bases were found to be linked. SYLLABUS FOR PRACTICAL Observation on floral biology – anthesis and pollination – selfing and crossing techniques ... Barn yard millet, Proso millet and Foxtail millet. Autogamy is the closest form of inbreed The activity of fruit ripening and fruit fall was at its peak in the first rainy season in order to utilize the available soil moisture for seed germination and seedling establishment. Vegetable crops. i) monoecy and ii) dioecy. Seed Propagated Rice, Wheat, Barley, Oats, Chickpea, Pea, Cowpea, Lentil, Green gram, Black gram, Soybean, Common bean, Moth 3) Study of floral structure of self pollinated crops. The plants regenerated from mutated branch produced flowers, which were of the same colour/shape, indicating the development of solid mutant in relatively short period of time. embryogenesis studies and ploidy analysis. Pulses: Redgram and Bengal gram, Green gram, Black gram and Cowpea; Soybean, Horse gram and Lab-lab. Among the pollination sequences, day 2 (the day after emasculation) contributed a greater percentage progeny (45%) than day 1 (35%) or 3 (20%). You can request the full-text of this article directly from the authors on ResearchGate. Pollen germination percentage and number of flowers for each clone were also investigated. 2007, 2008). A linkage map with 11 linkage groups (LGs) was constructed from this F2 population using 145 SSR, 117 RAD-seq and 2 morphological markers. Day 4…” Alien Gene Transfer in Crop Plants, Volume 2. From these results, we suggested that three points for breeding programme of Acacia hybrids, namely, availability of each reciprocal crossing, caution for using A. auriculiformis clones in interspecific pollination and possibility of self-compatibility by tube pollination. Working off-campus? In our laboratory, we have developed a method to induce in vitro flowering of some Dendrobium hybrids (Sim et al. Mechanism promoting cross-pollination. Chen, N. C., L. R. Baker, and S. Honma, 1983: Interspeci®c crossability among four species of Vigna food legumes. Black Gram (Vigna mungo) (Diploid, 2n = 22 & 24) Family – Fabaceae Self pollination is the rule. Many highly segregation distorted markers were found on LGs 5, 6, 7, 8, 10 and 11. Genetics of domestication have been investigated in most of cultivated Vigna crops by means of quantitative trait locus (QTL) mapping. Since three of the five QTLs, including the largest effect QTL, detected for SDNPPD were mapped to genome regions that showed high segregation distortion, those QTLs may be associated with genetic compatibility and fertility, and thus seed production. Pollinated pistils were treated with gibberellic acid (GA3) (70 p.p.m.) A Homoploid Hybrid Between Wild Vigna Species Found in a Limestone Karst. 所需天數的分佈時間(GT90-GT10)，(Imperial Blauwe Spiraal(和(Imperial Karmijn Koning(兩品種分別在5和10℃發 芽時最短，為9.1和7.8天。GFP、MGT、GT50、GT90-GT10在光照中或黑暗 下的結果相似。周年栽培生長試驗，以秋、冬兩季播種的植株的切花品質 才具有商品價值。兩種不同發芽溫度之植株表現差異小。(Imperial Blauwe Spiraal(和(Imperial Karmijn Koning(兩品種在苗期時，利用涼 溫(日/夜溫18/12℃)處理，13週的植株株高最高，分別為67.0和64.2公分 ，其切花品質最好。到花日數、株高、鮮重、總節數、花穗長度、小花數 目、著花節位、側枝數、頂部三節間長、莖粗均隨著處理涼溫期間增長而 增加。(Imperial Blauwe Spiraal(和(Imperial Karmijn Koning(兩品種 利用24小時長日處理的植株，分別較處理自然日長的植株早15.4和17.9天 開花，但切花品質不具商品價值。而處理自然日長株高最高，分別為97.8 和91.8公分，其切花品質最好。而利用暗期中斷長日處理的植株較處理自 然日長的植株可提早7.4和9.9天開花，其株高與自然日長處理的植株差異 不大。而利用暗期中斷處理60天的植株會比處理自然日長的植株，分別 早6.7和8.6天開花，且株高與自然日長處理的植株無顯著差異。 The cultivars of Delphinium ajacis L.(Imperial Blauwe Spiraal( and (Imperail Karmijn Koning( were used through this study.The objectives of this study were to determine the effects of different temperatures and light on seed germination of Delphinium ajacis L.,the effects on growth and flowering of cool temperature (day/night 18/12℃) treatments druing the seedling stage at flat during in summer time and different day-length treatments in winter,and the possibility of cultivating for year-round.The final germination percentage (FGP) of (Imperial Blauwe Spiraal( and (Imperail Karmijn Koning( both were the highest at 5℃,divided into 90.5% and 88.8%.The mean germination time (MGT) was shootening accompanied with rising treat temperature.It was the shortest at 15 ℃,divided into 16.1days and 16.2days.Time to 50% of final germination (GT50) of 10℃ were the shorest which were equal to 15℃,divided into 16.1days,16.2days and 15.5days,15.7days.Days from 10% to 90% of final germination (GT90-GT10) of (Imperial Blauwe Spiraal( were shortest at 5℃ which were 9.1days.GT90-GT10 of (Imperial Karmijn Koning( were shortest at 10℃ which were 7.8days.FGP、 MGT、GT50、GT90-GT10 were about equal in light or darkness.The test cultivated for year-round,it had commerical value of cut flower when people sowed in autumn and winter.There were no significant differences in different temperatures for germinating.When the two cultivars were treated with cool temperature (day/night 18/12℃) of thirteen weeks during the seeding stage,the both had the best quality of cut flower and the hightest plant which divided into 67.0cm and 64.2cm.Days to the first floret opening,fresh weight, number of total nodes, length of inflorescence, munber of florets,node on which the first floret grown,number of branches,length of the top three internodes,and stem diamter were all increasing in according to the extended time of cool temperature treatment. A derivative line, KUG114, recorded yield superiority of 39.45% over the check cultivar ‘Mash338’ on the average of 14 multilocation research trials. seed color varies from cream, black, brown, yellow to green. It has a well-developed taproot and its stems are diffusely branched from the base. Black gram (Vigna Mungo L.) is popularly known as “Urad”, is one of the most important pulses crop, grown across India. 1991 ) Chromosome doubling using colchicine Chaisan et al. It is a highly self pollinated crop with cleistogamous nature. Enter your email address below and we will send you your username, If the address matches an existing account you will receive an email with instructions to retrieve your username, I have read and accept the Wiley Online Library Terms and Conditions of Use. Orchid breeders usually have to grow the thousands of seedlings from each seedpod to maturity before flower quality can be evaluated (Sim et al. Interestingly, 2 QTLs each for tuber width and tuber weight detected on LG2 and LG4 were located at similar position and wild allele increased tuber width and weight. 14 No. radiata x V. umbellata, by using intraspecific hybrid as parents. The rooted shoots were hardened and observed for morphological characters. However, high incidence of insect pests in these crops is a major constraint in achieving their potential productivity and resulting in yield instability over the years. All ray florets in each flower head and all flower heads in mutated branch were of the same colour and shape. The mutant floret colour was yellow with flat and incurving florets. The dried beans are prepared by cooking or milling. abiotic stresses have restricted potential expansion of black gram in new niches (Kumar et al., 2004). The application of growth regulators to pistils for delaying the initiation of abscission of pods is usual for numerous interspecific hybridizations. (Imperial Blauwe Spiraal( and (Imperail Karmijn Koning( treated with 24h day- length were 15.4days and 17.9days to the first floret opening than treated with natural day-length.But there were both no commerical value of cut flower.The plants treated with natural day-length both had the best quality of cut flower and the hightest plant which divided into 97.8cm and 91.8cm.The plants treated with night break were earlier 7.4days and 9.9days to the first floret opening than treated with natural day-length ,but there were no significant differences in the quality of cut flower.The plants treated with sixty days of night break and natural day-length which had no significant differences in the quality of cut flower between these,but the former got the first floret opening which were earlier 6.7days and 8.7days than the later. Poor crossability and partial fertility was also observed earlier by various workers in interspecific crosses involving Vigna species (Dar et al. Dicliny. It indicates an injurious effect of pollen with accumulated exposure of the trees on seed germination. This is the common form of out-breeding. Black gram is a highly self-pollinated crop with cleistogamous The percentage increase/decrease in yield ranged from −35.48 to 50.31 over the check cultivar (‘Mash338’, female parent). Learn more. . Colours of epicotyl and stem bases were found to be linked. Breeding Insect Resistant Crops for Sustainable Agriculture. 2007). This is of two types: viz. (i) open to all visitors, (ii) bird excluded, and (iii) all visitors excluded, we established that birds contributed significantly more to fruit (2.3–5.6 times) and seed (1.3–1.4 times) set than insect or self-pollination, respectively. The breeding process normally comprises of these essential stages: 1) pollination and seedpod maturation, 2) in vitro seed germination, protocorms development and growth of seedlings, 3) ex vitro establishment of seedlings and growing seedlings to maturity, and 4) assessment of flower characteristics and quality (Hee et al. Proc. Here pollination occurs before floer opening (cleistogamous) in night. Am. Zombi pea (Vigna vexillata (L.) A. Classification of crop plants based on mode of pollination and mode of reproduction Mode of pollination and reproduction Examples of crop plants A. Autogamous Species 1. Pollination is of two types: viz. Pulse crops (Red gram, Black gram and Green gram) are basically self-pollinated in nature and don’t need any external pollination practices. A legume (/ ˈ l ɛ ɡ j uː m, l ə ˈ ɡ j uː m /) is a plant in the family Fabaceae (or Leguminosae), or the fruit or seed of such a plant. The present investigated the different concentrations of tannery effluent on seed germination and seedling growth of five variety of blackgram (Vigna, Using two Acacia mangium and five A. auriculiformis clones, Acacia hybrids were reciprocally artificially pollinated by tube pollination to determine which cross combination was more appropriate.
