Line× tester analysis was carried out involving fourty two lines and three testers in maize for
assessing the combining ability for yield and its component characters. Hybrids recorded
significant variance for all characters studied. Variance due to parents were significant for
characters viz., days to 50% tasseling, days to 50% silking, plant height (cm), ear height
(cm), cob length (cm), cob girth (cm), number of grain rows per cob, number of grains per
row, number of grains per cob, 100 grain weight (gm) and grain yield per plant (gm). The …

Combining ability analysis for yield and its component traits was performed with twenty four
lines, three testers and the resulting 72 hybrids using Line x Tester analysis. The interaction
of Line x Tester was highly significant for all the characters studied except number of leaves
per plant. Variance due to sca was greater than gca variance for the traits viz., grain yield per
plant, cob diameter, cob length, plant height, ear height, leaf length, 100 grain weight, grain
rows per cob, days to 50 per cent tasseling and days to 50 per cent silking. The variance due …
