Abstract:
Eleven castor (Ricinus communis L.) genotypes consisting of four lines and seven testers and crossed in a line × tester mating design. The ratio of GCA and SCA variance showed non- additive gene action was per-dominant controlling all the traits except for oil content. None of the parents and hybrid found good general and specific combiner for all the characters, respectively. Parental lines GP-525, GP-532 and SKP-84 were good general combiners for seed yield per plot and for one or more characters. While SKP-84 × GP-664, ANDCP-8-1 × GP-525 and SKP-84 × GP-532 were the best specific combiner for seed yield per plot. The higher economic heterosis for seed yield per plot was exhibited by the hybrid ANDCP 8-1 × GP-525 (24.0%) followed by SKP-84 × GP-525 (21.9%), SKP-84 × GP-532 (19.2%) and SKP-84 × GP-664 (16.3%). The per se performance of parents and hybrids were not always reflected in high GCA and SCA effects.
