Abstract

A study was conducted to determine gene action, heritability and number of effective genes controlling twelve characters from seven parents raised in a half diallel design. Over dominance governed most of the traits including yield components. Genetic and graphic. analysis showed that there is preponderance of non-additive gene action for the characters viz. plant height at first flowering, individual fruit weight, fruit length, fruit girth, plant height at final harvest, yield per plant and protein content in fruits. This study has brought out that the hybrids Varsha Uphar x Arka Anamika and OHD-1 x Varsha Uphar could be selected for the exploitation of heterosis and commercial utilization.

Keywords: Okra, Half diallel, Over dominance, Yield components.
