摘要：

The inheritance of resistance to Mungbean Yellow Mosaic Virus (MYMV) in green gram was studied from the crosses between a MYMV resistant genotype IPM 02-03 and two susceptible genotypes BKG and OUM 11-05. The F-2 generation of the two crosses, BKG x IPM 02-03 and OUM 11-05 x IPM 02-03 along with the parents were screened for MYMV resistance in natural field conditions using infector rows of MYMV susceptible variety KPS 2. Each plant in the segregating generation of both the crosses was screened for MYMV resistance according to the MYMV score proposed by Alice and Nadarajan(1). The chi square test confirmed the segregation ratio of 3:1 susceptible: resistant plants in the F-2 generation of both the crosses. This indicates that the MYMV resistance in green gram is controlled by monogenic recessive gene.
