Abstract

An attempt to evolve a high yielding long duration redgram variety for rainfed sowing in Tamil Nadu has resulted in the isolation of a promising culture CoRG 14. It is a gamma irradiated mutant of SA 1 and it out yielded the standard check SA 1 with tolerance to pod borer and drought. It has an indeterminate plant type maturing in 170-180 days suitable for adipattam (July-August). The culture has higher protein (19.14%) and methionine (1.15) than SA 1. Hence, it is released as Co 6 for pure and mixture cropping under rainfed condition in Tamil Nadu to replace SA 1.

Keywords: Redgram, Long Duration, Gamma Mutant, Indeterminate Plant Type, Helicoverpa armigera.
