Description Improvement in production and productivity of mungbean is difficult mainly due to major viral disease; Yellow Mosaic Disease (YMD) caused by Mungbean Yellow Mosaic India Virus (MYMIV) more prevalent in Northern Indian subcontinent and MYMV more prevalent in Southern Indian subcontinent. Management of plant diseases through host resistance is considered as one of the best options available for crop protection hence breeding for YMD is essentially required in case of pulses. In case of MYMV, conflicting reports are available on the mode of inheritance of resistance and but there is a need to know the genetics of MYMIV for use of host resistance in breeding programme. In this present study, we studied mode of inheritance for resistance against MYMIV. Four crosses between resistant and susceptible genotypes were made. The six generation P1, P2, F1, BC1, BC2 and F2 were grown along with infector row for evaluation against MYMIV resistance. The segregation of resistance responses in F2 populations in ratios of 9 S: 3 MS: 3 MR: 1 R suggested that the resistance was governed by two recessive genes. The study of test crosses/ back cross BC1 with all susceptible plants and in BC2 ratio of 1S: 1MS: 1MR: 1R also supported that two recessive genes are involved in imparting resistance against MYMIV.
