ABSTRACT

Six lines and three testers were used to make crosses as per line x tester analysis, ten
characters including quantitative and qualitative traits were tested for gca and sca in F1’s and
their parents. The results were indicative of predominance of non additive gene actions for all
the traits studied. The variances of general combining ability (gca) and specific combining ability
(sca) were highly significant. Based on the gca effects of parents, the line IR 58029-99-3-1-3
(L5) and tester BR 4828-2-2-1(T2) were recorded negative gca effects for days to 50 per cent
flowering and plant height. In addition, the line IR 58108-3-1-1-2 (L6) and tester BR 802-78-
2-1-1 (T3) possessed high gca effects, the cross IR 44962-161-2-4-4-2/AS 37800 and IR
58108 -3-1-1-2/AS 37800 showed highly significant results for days to 50 per cent flowering
and grain yield per plant respectively.
