Abstract

The yield per plant showed strong genotypic correlation with number of fruits per plant, fruit weight and fruit girth. Significant negative correlation of yield with days to 50% flowering was noticed. Plant height and crop duration showed positive significant genotypic correlation among themselves. It is noteworthy that the present study suggested highly significant negative correlation between number of fruits per plant and fruit weight both at genotypic and phenotypic levels, whereas number of fruits per plant had positive genotypic correlation with fruit girth. The number of fruits per plant and fruit girth besides being positively associated with yield, showed positive genotypic correlation between them. These two characters had high heritability too. Hence it would be worthwhile to give due consideration to these characters in selection programs aimed at yield improvement in okra.Highly significant positive correlation between per cent fruit infestation and larval count of shoot and fruit borer in 25 fruits suggested that fruit damage criteria may be employed for the evaluation of shoot and fruit borer resistance in okra.
