abstract
At the Vegetable Research Farm, Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, research on twenty different accession of okra [Abelmoschus esculentus (L.) was conducted in a randomised block design with three replications during the rainy season of 2023 to study the genetic variability, heritability, genetic advance, and characters association. There was discovered to be a large degree of genetic diversity in the materials for all genotypes under consideration, as indicated by the analysis of variance, which revealed extremely significant differences for each genotype. The phenotypic coefficient of variance was greater than the matching genotypic coefficient of variation for every research participant. There is enough variety in the number of branches per plant and chlorophyll concentration, as evidenced by the significant genotypic and phenotypic variance in both traits. High heritability was noted for the following parameters: height, fruit production per plant, length of internodes, number of internodes on main stem, number of branches per plant, amount of fruit per plant, and predicted genetic advancement represented as a percentage of the mean. The prevalence of additive gene activity was suggested by this data. It can be concluded that due weight should be given to plant height, number of internodes on main stem, length of internodes, number of branches per plant, fruit length, fruit weight, number of fruits per plant, and fruit yield while imposing selection for genetic improvement of fruit yield per plant in okra. These conclusions are based on performance, heritability, and genetic advance as a percent of mean, the genotypes. In order to develop high-yielding okra varieties and hybrids, the genotypes Parabhani Kranti, Arka Anamika, Azad Bhindi, Varsha Uphar, Kashi Vibhuti, Pusa Makhmali, VRO-3, and VRO-4 that had higher values for the aforementioned characters can be further tested and used in future breeding programmes.
