Two cultivars of okra were selected based on different pod colours to investigate the inheritance of pigmentation in pods. Direct crosses were made among green and red cultivars of okra to generate the F1's in the 2021 Kharif season. In Kharif 2022, the F1's were planted to generate the F2 generation and backcrosses (B1 and B2) were attempted. The parents, F1, F2, B1 and B2 generations were evaluated on the field in summer 2022 farming season at Experimental Farm, Department of Vegetable Science, Dr Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh, India using randomized complete block design, with three replications. The Chi-square Test of goodness assessed the phenotypic segregation pattern to fit. F1 pods were always equal to the phenotype of the male parent. F2 populations resulted in a 3:1 ratio producing red and green pods indicating dominant or single gene control for this trait. This study also revealed a monogenic/monohybrid pattern for the inheritance of pod pigmentation with the pigmented parent dominant over the non-pigmented parent. The genotype of the male parent influenced all the populations. The paternal effect resulted from the transfer of gene products from paternal to offspring, with evidence of the effect of a single gene with a dominant allele for the red phenotype.
