Abstract

An experiment was conducted to study the Combining ability in newly derived lines involving line x tester analysis with ten lines and three testers at All India Co-ordinated Maize Improvement Project, Agricultural Research Station, Arabhavi, UAS, Dharwad. The results revealed that among ten female lines, L2 is the best general combiner for plant height, ear height, ear length, 100-grain weight, grain yield per hectare and fodder yield per hectare. Whereas, among thirty crosses, L8×T3 is the best specific combination for plant height, ear height and grain yield per hectare.
