Abstract:

Eight parental lines of okra and their 28 F1 hybrids obtained from half diallel were studied to identify the good general and specific combiners for yield and quality parameters. Both general a combining ability (GCA) and specific combining ability (SCA) variances were highly significant for all the characters indicating the importance of both additive and non-additive gene actions. The parents KO1608 and KO1606 were identified as good general combiners for number of fruits per plant, yield per plant, yield per plot and yield per hectare. The parent KO1608 was good general combiner for fruit weight and number of ridges on fruit surface and the parent KO1606 was identified as good general combiner for average fruit weight. The crosses KO1601 x KO1605 and KO1603 x KO1606 were identified as good specific combiners for average fruit weight, yield per plant, yield per plot and yield per hectare. The maximum sca effects were observed in the crosses KO1601 x KO1604 and KO1606 x KO1607 for number of fruits per plant and fruit length respectively. The cross KO1602 x KO1605 exhibited highest sca effects for fruit diameter and number of seeds per fruit.
