 ABSTRACT

Heterosis breeding based on the identification of parents with desirable characteristics and their cross compatibilities is capable of producing F1 hybrids and transgressive segregants with superior yield. To achieve high degree of heterotic response, it is essential to have knowledge about performance of desirable parents. This work, therefore, involved studies on the expression of heterosis for key quantitative agro-morphologic traits by 27 F1 offspring obtained from intra-specific and 24 F1 offspring from inter-specific hybridization among ten parental accessions of okra.  The performances of their F1 offspring were evaluated against the respective parents for expression of heterosis for key quantitative traits including days to 50% germination, days to 50% flowering, plant height, fresh fruit weight, length of pod and number of seeds per pod. It was observed that. the cross, T3 X T1 came out with the highest BPH for days to 50% germination while the crosses AG X T4, AG X YL and T2 X T3, respectively recorded highest BPH for (days to 50% flowering and number of branches per plant), (length of pod and Fresh fruit weight) and (Plant height and number of seeds per pod).
