Line x Tester analysis involving 34 females and 3 males from diverse origin revealed that both additive and non-additive gene actions were important in controlling the characters studied.  HYD.SEL 13, HYD.SEL 10 and HYD.SEL 14 among females and CI-5 and CI-4 among males were the good general combiners for grain yield and its components.  These parents should be extensively used in the crossing programme to exploit maximum genetic variability and isolate transgressive segregants for grain yield and its components.  Crosses viz., HYD.SEL 8 x CI-5, NG-4 x CM-111 and CM 114 x CI-4 showed significant sca effects as well as better parent heterosis. Such crosses are suited to be used directly in hybrid production programs in order to utilize the hybrid vigours.
