Correlation and Path Coefficient Analysis Studies for Quantitative Traits in Okra [Abelmoschus esculentus (L.) Moench]

摘要

Investigation on correlation and path coefficient was carried out among 14 different yield attributing traits in 32 advanced breeding lines of okra during summer season, 2012-13. Genotypic and phenotypic correlation coefficient studies revealed that fruit yield per plant exhibited positive and significant correlation with number of pods per plant, number of nodes per plant, average pod weight, pod width, plant height and pod length. Whereas, days to 1 “ flowering and days to 50% flowering recorded significant negative correlation with pod yield per plant. Genotypic path coefficient analysis revealed that plant height and pod length recorded maximum positive direct effect on pod yield per plant. Whereas, phenotypic path coefficient analysis revealedthat number of pods per plant, average pod weight and plant height recorded maximum positive direct effect on pod yield per plant. Thus pod yield in okra can be improved by selection of traits with higher number of pods per plant, number of nodes per plant, average pod weight and pod length.
