Abstract

The genetic variability, correlation and path coefficients analyses were studied in 22 diverse genotypes of okra for fruit yield and its component traits during summer 2003. The values of PCV were higher than that of GCV values for all the seven traits indicating influence of environmental effects in expression of these traits. The GCV, heritability and genetic advance as percentage of mean were higher for fruit yield, average fruit weight, plant height and fruit length which might be attributed to additive gene action resulting their inheritance. The fruit yield was significant and positively correlated with fruit length and average fruit weight. Path coefficients revealed that fruit girth had the maximum direct effect followed by fruit length towards fruit yield. Thus, the fruit yield in okra can be improved by selecting for higher fruit length, fruit girth and average fruit weight simultaneously.
