Breeding objectives 1. In this investigation the nature and extent of DNA variation between thirteen diploid and one polyploid species have been estimated. in wild mungbean (Vigna radiata var. It had been reported earlier that restriction of gene flow between these species was partly due to hybrid inviability and partly due to chromosomal differentiation. There has been confusion on the taxonomic status of Vigna mungo and Vigna radiata; because they are closely related it was proposed that they be grouped into a single species. Both the varieties were found to possess 2n =22 metacentric chromosomes. Vigna mungo . Barimash-1 and Barimash-3 were cytologically studied after staining with orcein and CMA. silvestris (Lukoki, 1980). INTRODUCTION. … Email(: ghafoor59@hotmail.com. This legume species was moved from the genus Taxonomy. Name Reference IPCN Reference Gametophytic Count Sporophytic Count Country ; Vigna mungo (L.) Hepper: Sharma, P. C. & P. K. Gupta. Both the varieties were found to possess 2n =22 metacentric chromosomes. However, none of the maps resolved 11 LGs, which is the haploid chromosome number of mungbean. Wild species of Vigna are known to exhibit great range of phenotypic and genotypic diversity leading to development of several varieties and cultivars. ... More number of Back crosses suggested. L. cultivar ‘Azad-2’ with the root-knot nematode and treated with two biofertilizers viz. cM), number of markers (102-255 markers), number of linkage groups (LG) (12-14), and level (12-30.8%) and regions of marker distortion. It is a cheap source of dietary protein (24%). 1. It produces about 1.5 to 1.9 million … Vigna mungo var. In Jingnong 6, maximum markers were found on chromosome 1 (14 964), … silvestris. 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. 313 001. Use of biochemical markers for genetic diversity and determining QTLs in Vigna mungo germplasm . Abstract. Mungbeans are a good source of dietary protein, folate and iron. It also contributes 76% carbohydrate 3-5% Fiber, 1.74% … In India the area production and productivity of blackgram was 4.49mha with 2.93 m tonne … 20 per page; 50 per page; 100 per page; Search Results. New chromosome number in the genus Vigna Savi (Leguminosae-Papilionoideae) by E. R. Forni-Martins (*) Abstract. V. mungo Total length of diploid complements and range of chromosome length were more or less same in the two varieties. Sterility is the main problem. Blackgram (Vigna mungo L. Hepper) popularly known as urdbean or mash, is a grain legume domesticated from V. mungo var. infect mungbean (Vigna radiata) at low levels in the field, multiply during grain storage and can destroy seed stocks in a few months. Vigna mungo is cultivated in approximately 5 million hectares worldwide. To The chromosome number showed a wide range … Although Jingnong 6 and Kyungwonpat cultivars were from the same species, at chromosome level substantial variation in SSR abundance was observed. Bruchid beetles are an important storage pest of grain legumes. silvestris (Lukoki, 1980). Introduction. 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]. It belongs to family leguminoseae with chromosome number 2n=2x=22.Blackgram is reported to be originated in India. It belongs to family leguminosae with chromosome number 2n = 2x = 22. Chromosome 3 had minimum number of repeats (6579) having maximum SSR density per Megabase (Mb) (573.2). It is grown mainly in rainy and/or summer seasons. However information regarding their chromosome biology is by and large lacking. 1982. Search Menu; Account Menu; Menu; Sign In ... only about half of these genome assemblies were anchored to chromosomes. sublobata TC1966 and in cultivated mungbean line V2802. The low frequency of reports of 2n = 18 in the tribe Phaseoleae and in the family … Identification of single nucleotide polymorphism markers associated with resistance to bruchids (Callosobruchus spp.) Green bean cultivation is relatively easy with a small risk of failure. Mungbean is mainly cultivated today in China, India and Southeast Asia but can be found in dry regions within Southern Europe and United States. 20 per page . strain Bs-5. 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. and V. unguiculata (Chaudhary et al ., 2007). CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Two varieties of Vigna mungo viz. Cytogenetical investigations, so far, on the organisation and evolution of the genomes of Vigna species have proved difficult due to small chromosome size, large chromosome number and uniformity in chromosome shape and size within and between the complements. sylvestris.
