Evaluation of staygreen sunflower lines for yield under drought conditions (Helianthus annuus L.)

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.
