Abstract:
The present investigation was carried out at the experimental farm, School of Agriculture, Lovely, Professional University, Jalandhar, Punjab, during 2021-22. Fifteen different germplasm L1 to L15 were collected from NBPGR, New Delhi and sown during the second fortnight of March in Randomized block design (RBD) with three replications. To determine the nature and magnitude of variation among okra genotypes for different growth and yield-related characters, and to identify the potential genotypes with promising attributes under conditions of Punjab's Doaba region. The observations on different traits were recorded following the standard procedures. The genetic divergence among the 15 okra genotypes were evaluated for range, mean, phenotypic coefficient of variation (PCV), genotypic coefficient of variation (GCV), heritability and genetic advance as a percentage of mean. The genotypic and phenotypic coefficients of variation were enumerated to compute the existing variability in genotypes.
The genotype EC 169472 performed best in terms of the maximum average weight of the pod (21.5 g) as well as it had the highest plant height (122.8 cm). Genotype EC 169455 contained a maximum pod length (10.7 cm) and pod diameter (2.15 cm). A maximum number of branches per plant is found in genotype EC 169453 (9.80). The highest stem diameter is observed on genotype EC 169464 (9.34 mm). The traits responsible for earliness such as days to first flowering (43.0 days), days to first fruits set (48.0 days) and days to first fruit picking (55.0) were recorded for genotype EC 169472. It may be concluded that genotypes EC 169472, EC 169455, EC 169453, EC 169464 and EC 169472 performed best in terms of growth and yield traits.
