Abstract

                                Out of 281 cultivars of black gram oberved for their reaction to yellow mosaic classe under natural conditions of spiphytotics, 15 cvs. remained free from infection, 11 cva. were tolerant, 20 cvs, ware moderately tolerant, 33 cva. were susceptible and 202 cvs. were highly susceptible. The studies revealed that major set back to pod beering maturity and yield in black gram [Vigna mungo (L) Hepper] occurred at, 25% infection Intensity of YMV. Therefore, the use of parent material even with 25% YMV Infection should be discouraged in the hybridzaton programme.
