Abstract

The experiment was undertaken with thirty eight genotypes of okra [Abelmoschus esculentus (L.) Moench] to conduct the correlation and path coefficient analysis to work out the inter-relationships among the traits. From the analysis it was observed that at genotypic and phenotypic levels, days to 50 % flowering exhibited significant positive correlation with number of branches per plant. Plant height showed significant positive correlation with number of fruits per plant followed by fruit diameter. Number of fruits per plant showed significant positive correlation with fruit length. Fruit length exhibited significant positive correlation with number of seeds per fruit. Fruit diameter showed significant positive correlation with edible yield per plant. At both genotypic and phenotypic level, path coefficient analysis revealed that direct effect was maximum in case of fruit diameter. The negative direct effect was maximum, in case of number of branches per plant. However, fruit diameter showed significant positive highest indirect effect on yield and number of branches per plant showed significant negative indirect effect on yield. The traits which are correlated positively with yield can be used as selection criteria in crop improvement programmes. The characters having maximum direct and indirect effects can also be used in breeding programmes. The residual factors were 0.9716 and 0.5823 at phenotypic and genotypic levels, respectively indicating that there are some other factors which have not been considered here and need to be included in this analysis to account fully for variation in yield.
