| description | The objective of the present study is to estimate the combining ability effects among parents and their crosses in pearl
millet, to identify promising cross combinations for grain yield and its component traits. In combining ability analysis,
the extent of sca variance was higher than gca variance for all of the characters demonstrating the predominance of
non-additive gene action except for panicle length and 1000-grain weight. The estimates of general combining ability
suggested that parents, RIB 17 S/109, RIB 16300, RIB 37-40 S/17, RIB 13-16 S/17, ICMA 96666 and ICMA 94111
were good general combiners for yield and its contributing characters. The best hybrid, ICMA 94111 x RIB 16296
involved low x low performing parents which exhibited high positive and significant SCA effect for grain yield and most
of the yield contributing and quality traits like protein, iron and zinc. These good combiner lines may be exploited to
develop iron and zinc rich hybrids along with grain yield to alleviate malnutrition in people of the country. |
