Validation of CYR-1 marker linked with yellow mosaic virus resistance in black gram (Vigna mungo L. Hepper)

Published on

The inheritance of yellow mosaic virus (YMV) resistance
was studied in blackgram using the molecular marker and
F2 population derived from the cross Keonjhar
Local(susceptible) × OBG-31(resistant). Assuming
Mendelian inheritance, almost perfect fit to a ratio of 3S:1R
in segregating population suggested a single recessive
gene controlling YMV resistance in V. mungo. The presence
of recessive gene was further confirmed by the linked DNA
marker of 1236 bp named ‘CYR1’. Amplification of CYR1
marker from the genomic DNA of phenotypic resistant
individuals from segregating F2 populations and F3 families
revealed a tight linkage between this marker with the YMV
