Correlation analysis for fruit yield and its related traits in okra [Abelmoschus esculentus (L.) Moench]

Abstract

The goal of the current investigation was to examine the relationships between genotype and phenotype for traits that contribute to yield. Eleven parental lines, including three checks, make up the experimental material for this study. The Lx T mating design was used to create 33 cross combinations from 11 female lines and 3 testers, and sufficient F1 seeds were produced in the Kharif of 2021. The experiment was carried out to determine the direction and strength of the association between characters, correlation studies were conducted at both the phenotypic and genotypic levels. It shows that environmental factors had a relatively small impact on the genotypic expression of correlation, which was a strong inherent association between the various studied characters. Fruit yield per plant was significantly positively correlated with plant height, number of nodes per plant, internodal length, number of fruits per plant, fruit weight, fruit length, and weight of 100 seeds. This shows how these characters have simultaneously improved due to selection.
