Use of biochemical markers for genetic diversity and determining QTLs in Vigna mungo germplasm . Sterility is the main problem. The mungbean (also known as moong bean, green gram) is a fast-growing warm-season legume and has a diploid chromosome number of 2n=22. In this study we employ GWAS to examine the genetic basis of variation in several important traits in mungbean, using the mini-core collection established by the World Vegetable Center, which includes 296 accessions that represent … Restricted gene flow between the four species, Vigna radiata, V. mungo, V. umbellata and V. angularis limits the potential for improved production and adaptation of these species in different agroecological systems. 1982. silvestris (Lukoki, 1980). Mungbeans are a good source of dietary protein, folate and iron. - The chromosome number of Vigna candida (Vellozo) Mar&chal, Mascherpa & Stainier was determined as 2n=18, being the first report of this number for the genus Vigna (2n= 20, 22 and 24).

Uninoculated untreated plants served as control. 313 001. It is a cheap source of dietary protein (24%). Introduction. Mungbean (Vigna radiata (L.) R. Wilczek, or green gram) is important tropical and sub-tropical legume and a rich source of dietary protein and micronutrients. sylvestris. in wild mungbean (Vigna radiata var. It is popularly known as “urd bean and mash” is an important short duration and selfpollinated Kharif legume crop and is an important part of Indian diet. None has been found more suitable for transformation as in of methods developed so far for Vigna species, ex- Vigna radiata (Jaiwal et al ., 2001; Sonia et al ., 2007), cept in V. angularis (Yamada et al ., 2001), explored V. mungo ( Saini et al ., 2003, Saini and Jaiwal, 2005) this possibility. 20 per page . Blackgram is reported to be originated in India (Zukovskiji, 1962).India is the world’s largest producer as well as consumer of blackgram. Bruchid beetles are an important storage pest of grain legumes. Number of results to display per page. Vigna mungo is cultivated in approximately 5 million hectares worldwide. Two varieties of Vigna mungo viz. Vigna mungo . Among the various pulses, blackgram is an important one which contains approximately 25-28% protein, 4.5-5.5% ash, 0.5-1.5% oil, 3.5-4.5% fibre and 62-65% carbohydrate … 20 per page; 50 per page; 100 per page; Search Results. The chloroplast genome of this species has not been previously reported. The range of median and submedian chromosomes in chromosome number in many Vigna species. An induced mutant, multiple-organ gigantism (MOG), of black gram (Vigna mungo) has been obtained, which shows gigantic leaves, fruit, seed, and architecture (plant height) but lower number of pods per plant. Callosobruchus sp. Wild species of Vigna are known to exhibit great range of phenotypic and genotypic diversity leading to development of several varieties and cultivars. New chromosome number in the genus Vigna Savi (Leguminosae-Papilionoideae) by E. R. Forni-Martins (*) Abstract. Bacillus subtilis . In Jingnong 6, maximum markers were found on chromosome 1 (14 964), … Blackgram is reported to be originated in India (Zukovskiji, 1962). silvestris. 1. silvestris (Lukoki, 1980). It belongs to the family Leguminosae, subfamily Papilionoideae, clade Millettioid [1], and is a tropical legume crop species that is cultivated in Asia, Africa, and America [2]. It is grown mainly in rainy and/or summer seasons. Both the varieties were found to possess 2n =22 metacentric chromosomes. Few plants obtained revert back to parental form. From the results, it was evident that . A study was undertaken on the variation in chromosome number of cells from callus tissues originating from cotyledon, hypocotyl and embryonal axis explants of Vigna mungo. It belongs to family leguminoseae with chromosome number 2n=2x=22.Blackgram is reported to be originated in India. silvestris is reported to be immune to bru-chids (Fujii et al. Barimash-1 and Barimash-3 were cytologically studied after staining with orcein and CMA. Identification of single nucleotide polymorphism markers associated with resistance to bruchids (Callosobruchus spp.) Total length of diploid complements and range of chromosome length were more or less same in the two varieties. Embryo Culture and Chromosome Doubling Results Crosses Green Beans and Black Beans Resume of M. Kosmiatin and I. Mariska CHAPTER I Preliminary 1.1 Background Mung bean (Vigna radiata L. Wilczek) including crops that have long been cultivated in Indonesia (Arora and Mauria 1993). In this investigation the nature and extent of DNA variation between thirteen diploid and one polyploid species have been estimated. The plants were grown in soil at N50 and N100 doses of urea. However, none of the maps resolved 11 LGs, which is the haploid chromosome number of mungbean. infect mungbean (Vigna radiata) at low levels in the field, multiply during grain storage and can destroy seed stocks in a few months. 1989; Dongre et al. It produces about 1.5 to 1.9 million … Mungbean (Vigna radiata L. Wilzeck) known as green gram and mashbean (Vigna mungo L. Happer) as black gram are widely cultivated pulse crops belonging to family Fabaceae.In cereal based cropping system, these pulses are being consumed as supplemental crops. Email: goyalsoni@yahoo.com Abstract Seeds of two varieties, PU-19 and T-9, of urdbean (Vigna mungo (L.) Hepper) were treated with four … - Tropical grain legumes, such as black gram, Vigna mungo, and green gram, Vigna radiata (L.) R. V. mungo Although Jingnong 6 and Kyungwonpat cultivars were from the same species, at chromosome level substantial variation in SSR abundance was observed. It also contributes 76% carbohydrate 3-5% Fiber, 1.74% … Resistance against bruchid beetles has been found in wild mungbean V. radiata var. However information regarding their chromosome biology is by and large lacking. Barimash-1 and Barimash-3 were cytologically studied after staining with orcein and CMA. the black gram (Vigna mungo (L.)) with two main differences: the corolla of Vigna mungo is bright yellow while that of Vigna radiata is pale yellow; mung bean pods are pendulous whereas they are erect in black gram. A number of the wild species are highl Skip to Main Content. Pseudomonas fluorescens strain CHA0, and . Determination of the chromosome numbers of root tip tissue (2n=22) and nodule tissue revealed that nodule tissue contained both diploid and tetraploid cells but no other degrees of polyploidy. A systematic genetic analysis of colchitetraploids of Vigna radiata and V. mungo in three different generations (C 1, C 2 and C 3) was made using karyomorphology of chromosomes and heterochromatin distribution pattern among them.Autotetraploid of both species were produced using aqueous colchicine (0.15 and 0.20%) and maintained through three successive generations (C 1, C 2 … cM), number of markers (102-255 markers), number of linkage groups (LG) (12-14), and level (12-30.8%) and regions of marker distortion. Mung bean is sown on lighter soils than black gram (Göhl, 1982). It belongs to family leguminosae with chromosome number 2n = 2x = 22. A Comparative Study of Chromosomal Aberrations in Vigna mungo Induced by Ethylmethane Sulphonate and Hydrazine Hydrate S. Goyal* and S. Khan Department of Botany, Aligarh Muslim University, Aligarh – 202002 (U.P. Blackgram is an annual leguminous crop belongs to family Fabaceae and sub-family Papilionaceae with a chromosome number 2n=22 (Dana, 1980) and originated from Indian continent [De Candolle, 1882, Vavilov, 1926]. Organ size and architecture of plants are important traits affecting crop yield and agronomic practices. It belongs to family leguminoseae with chromosome number 2n=2x=22.
