Combining Ability of Grain Yield and Its Prime Yield Components Using Early Inbred Lines of Maize (Zea mays L.)

摘要

Combining ability studies were conducted using their 10 parents and 45 hybrids obtained from a-half diallel mating for grain yield and yield components. Hie studies revealed significant gca and sea effects for all the traits studied. The parents SK-2,SK-1 and SRRL-65 were found to be good general combiners for plant height, ear height and grain yield. The cross combinations CM-211 x ACROSS, SK-1 x SK-3, SRRL-79 x SK-1 and SRRL-65 x MH-12 showed high SCA effects for grain yield and yield related characters.
