Abstract:
The present investigation was undertaken to study the combining ability for yield and its component traits in okra. The experiment was carried out with six parents and 30 F1¬s (including reciprocals) obtained through diallel hybridization technique. The mean squares due to gca and sca and reciprocal effects were significant for all characters. Among six parents studied in a full diallel, parents AE-CBE-92 and AE-CBE-93 were adjudged as good general combiner for fruit yield and most of the yield contributing characters. Among hybrids, AE-CBE-93 x AE-CBE-921 (P2xP4) recorded additive gene action for fruit yield and few yield component traits. Selection could be applied in the early generation to improve fruit yield and yield component traits due to the presence of additive type of gene action. Hence the cross AE-CBE-93 x AE-CBE-921 could be subjected into pedigree breeding programme for the fruit yield improvement programme in okra.
