Moench) JF - <i>Electronic Journal of Plant Breeding</i> JA - EJPB VL - 5 IS - 1 SE - Research Article DO - UR - https://ejplantbreeding.org/index.php/EJPB/article/view/152 AB - Eight genotypes of okra were crossed in half diallel fashion to study the combining ability of the parents and gene action in respect of fruit yield and 12 other component characters. The magnitude of GCA variance was higher than respective SCA variance indicating predominance of additive gene action for expression of all the characters. The components of variance for both GCA and SCA were recorded to be higher for fruit yield per plant and plant height. Considering the genetic variance, it was higher due to SCA than that of GCA for all the characters except for flowering characters thus suggesting significant role of non additive gene action in the expression of former characters. The genotype IC-332453 and Parbhani Kranti were the best general combiners. The crosses that exhibited higher SCA effects and per se performance for fruit yield per plant were IC-33107 X IC-433665, IC-342075 X IC-332453, IC-43736 X Parbhani Kranti, IC-433672 X IC-332453 and IC-3307 X IC-4376. In these crosses atleast one of the parents is a good general combiner. Therefore, complementary type of gene effect might have played important role in expression of the character. ER -
