Validation of molecular markers linked to yellow mosaic virus disease resistance in diverse genotypes of green gram (Vigna radiata)

Marker assisted indirect selection of resistant genotypes using linked markers has been reported as an effective breeding approach for developing yellow mosaic disease resistant cultivars. Seven genotypes of greengram with different genetic makeup showing resistance reaction to yellow mosaic virus (YMV) were selected along with a susceptible one for molecular confirmation with respect to YMV reactions. These were screened with PCRbased technique employing primer pairs to validate efficiency and reliability of identified markers loci (CYR1 and YMV1).
