Abstract


GCA of 10 lines of okra (Abelmoschus esculentus) and SCA of their 45 direct crosses were estimated for 10 characters. GCA-SCA ratios were less than unity for the majority of characters, indicating non-additive gene action. Line Pl489782 was the best general combiner for marketable yield (weight of good pods per plant), total number of pods per plant and plant height. High positive significant SCA effect for marketable yield was shown by the crosses IHR4 x Pl 489782, Pusa sawani x Smooth green, Pusa Sawani x Pl 496620 and IHR4 x Green velvet. In general, parents with average/high GCA status produced hybrids with high SCA components and high heterosis.
