Abstract:

The phenomenon of staygreen nature with desired root traits is important consideration in drought tolerance breeding. The experiment was conducted using 28 inbred lines (including 2 checks) which were developed by mutation breeding from AICRP on oilseeds, MARS, AUS, Dharwad, and on the basis of SPAD reading and stay green nature, which were essential to extract moisture from deeper layer of the soil profile. These lines were evaluated under both normal and moisture stress condition in rain out shelter to study their root characteristics and the lines that performed well were categorised as stay green lines viz DSR-13, DSR-19, DSR-23, DSR-24, DSR-37, DSR-66, DSR-107 and DSR-132 which exhibited least reduction in their yield under moisture stress condition with desired root traits. Among them DSR-37 (35.15) and DSR-132 (33.85) shown maximum root length under stress conditions, and also average yield per plant was found to be higher (9.5 g/pl and 8.1 g/pl respectively) when compared to checks 95 C-1 and 6D-1 used. These inbred lines with better performing under stress condition were further used for the development of open pollinated varieties and also used for hybridization with available CMS sources (with good combining ability) to develop drought tolerant hybrids.
