Assessment of genetic variability and character association in okra [Abelmoschus esculentus (L.) Moench]

The present study was conducted at the College of Horticulture and Forestry, Acharya Narendra Deva University of Agriculture & Technology, Kumarganj, Ayodhya during the summer season of 2022-23. Plant material consisted of 31 genotypes of okra including 1 check namely NDO-10 in randomized block design of 45x30 cm2 with three replications. Evaluation was done for different yield and quality traits. Analysis of variance elucidated significant variations among the genotypes for all the characters studied. Based on mean performance, all variety were found highest total pod yield then the check variety NDO-10 (161.00 q/ha) like NDO-23-53 (291.06), NDO-23-39 (262.08), NDO-23-34 (252.00), NDO-23-42 (249.00) and NDO-23-52(248.93). The highest phenotypic, as well as genotypic coefficients of variation, were observed in case of total pod yield (23.784% and 22.48%) followed by pod yield per plant (23.086% and 21.941%). The heritability in broad sense ranged from18.1 per cent in case days to first pod harvest to 90.3 per cent for pod yield per plant. Highest value of genetic advance in per cent of mean was shown by total pod yield (43.77%). While days to first flower appearance exhibited lowest value (2.574%).
