Combining ability for grain traits in maize

摘要

Combining ability studies for grain traits revealed additive gene action for plant height, number of grain rows per cob, number of grains per row, cob weight, days to 50 percent silk and hundred grain weight. Based on the per se performance and effects UMI 760, Prabhat - 1 and JM 3181 - 1 were found to be the best parents for improvement of grain traits besides grain yield. Prabhat-1 X UMI 492, UMI 760 X JM 3181 and UMI 805 X UMI 805 X UMI 760 are suitable for recombination breeding.
