Abstract:
An investigation was carried out at Research Farm (C-Block) of Bidhan Chandra Krishi Vishwavidyalaya, Kalyani during Post-Kharif, 2022 with the objective to study phenotypic variations in seed yield attributing characters. The eight genotypes of okra collected from various sources were grown in randomized block design (RBD) with three replication and observations were recorded on days to first flowering, days to 50 percent flowering, plant height, capsule length, capsule diameter, seeds per capsule, capsules per plant and seed yield. Analyzed data revealed that there were significant differences in seed yield related parameters among the genotypes. Correlation studies showed that seed yield per plant had significant positive association with capsule length and seeds per capsule. These two attributes have a strong influence on seed yield. Further, path coefficient analysis revealed that seed per capsule had the highest direct effect on seed yield representing highest heritability (H²%) and genetic advance (GA%). Hence, number of seed per capsule is the foremost determiners for qualitative and quantitative improvement of the okra genotypes.
