Studies on Genetic Variability, Heritability and Genetic Advance in Genotypes of Okra [Abelmoschus esculentus (L.) Moench]

Abstract

Sixty-eight okra accessions were evaluated for genetic variability, heritability, and genetic advance in okra at Horticulture Research Centre, SVP University of Agriculture and Technology, Meerut (U.P.) during the year 2014-15 and 2015-16. Genetic variability analysis on sixty eight genotypes of okra (pooled data analysis) revealed high magnitude of genetic variability for the traist viz., pod yield and plant height under study. High magnitude of genotypic coefficient of variation (>20%) for number of pod yield and plant height indicated high degree of genetic variability offering great scope for selection of these characters. The genotypes under study showed moderate heritability (30-60%) showed the environmental influence. High heritability coupled with high genetic advance for the traits like plant height and pod yield per plant indicated the involvement of additive gene action and more chances of fixing by selection to improve such traits. The genotypes viz., B-02, KS-442 are noticed with great potential and can be utilized for improvement of okra germplasm.
