Assessment of stay green genotypes of sunflower for root traits under different soil moisture regimes

The phenomenon of stay-green and root traits are most important in drought tolerance breeding. The present investigation was conducted to identify the drought resistant staygreen genotypes with desirable root traits which are essential to extract moisture from deeper layers of the soil under drought conditions. Seven stay-green genotypes along with three non-staygreen checks were evaluated for root traits in PVP pipes with different soil moisture regimes under Factorial RBD design with two replications.
