Combining ability analysis in Finger millet (Eleusine coracana (L.) Gaertn.) under salinity

Six lines and four testers differing in their response to salinity were hybridized in Line x Tester design and combing abilityfor ten quantitative traits and Na-K ratio was investigated. The study revealed total variance due to lines x testers wassignificant for all the characters under investigation. Variance due to sca was higher for all the characters indicatingpreponderance of non-additive gene action. On the basis of per se performances and gca effects GPU28, CO12 and Vl 149were identified as best combiners for majority of the traits including grain yield per plant and Na+: K+ ratio. Based on per seperformance, sca effects and standard heterosis, GPU28 x CO13 and CO12 x TRY1 were promising hybrids for grain yield .Based on significant gca effects of parents and non significant sca effects it is suggested for recombination breeding todevelop tolerance under saline condition.
