Description
The aim of this study was to identify the molecular markers (SSR, RAPD and SCAR) associated with Mungbean yellow mosaic virus resistance in an interspecific cross between a mungbean variety, VRM (Gg) 1 X a ricebean variety, TNAU RED. The parental survey was carried out by using 118 markers (including 106 azuki bean primers, seven mungbean primers and five ricebean primers). This study revealed that 42 azuki bean markers (39.62%) and four mungbean markers (54.07%) showed parental polymorphism. These polymorphic markers were surveyed among the 187 F2 plants and the results showed distorted segregation or chromosomal elimination at all the marker loci (thus, deviating from the expected 1:2:1 segregation). None of the plants harboured the homozygous ricebean allele for the markers surveyed and all of them were skewed towards mungbean, VRM (Gg) 1, allele, except a few plants which …
