ABSTRACT

Horse gram Yellow Mosaic Disease (HgYMD) is one of the major limiting factor for Horse gram production in India which

may cause complete yield loss. Thirty seven genotypes of Horse gram were screened in a Randomized Complete Block Design (RCBD) with three replications under natural disease epiphytotic conditions during rabi, 2022. A total of eighteen horse gram genotypes exhibited resistant reaction with low Percent Disease Incidence with a maximum of 0.7 %. Among which, AVTH-12 have shown highly resistant reaction. The apparent rate of infection which depicts disease progression was calculated and found gradual increase in disease in all susceptible genotypes viz., HG-17-1, BSP21-7, BSP21-4, BSP21-3, Indira Kulthi-1, BSP21-5, Bilasa, BSP21-11.
