In this research, thirty-seven okra (Abelmoschus esculentus (L.) Moench) accessions selected from different eco-geographical regions of India were evaluated during two years (2011, 2012) for genetic variability, heritability and genetic association among fruit yield, quality and agronomical traits in randomized complete block design (RCBD) with three replications. The estimation of phenotypic coefficient of variability (PCV) and genotypic coefficient of variability (GCV) were high for dry matter, mucilage and mineral content. There was high % broad sense heritability and genetic advance in traits such as internodal length, dry matter, mucilage and mineral content suggesting the effect of additive genes for their inheritance and reliability of selection based on phenotype of these traits for crop improvement. Moderate to low heritability with low genetic advance was recorded for days to 50% flowering, average fruit weight, days to 50% emergence, days to first picking, fruit yield/plant, fruits/plant, first fruit producing node and nodes/plant, indicating the non-additive gene activity. The positive and significant phenotypic and genotypic association studies revealed that the selection based on fruits/plant, average fruit weight and nodes/plant would be fruitful and rewarding for effective improvement of fruit yield in okra. The genotypes (VRH-2XVRO-6)-1-1-2-1, (VRH-2XVRO-6)-9-2-1-3, Hissar Unnat, (IC-169469-1XPK)-1-2-1-2 and Parbhani Kranti were found to be promising for marketable fruit yield/plant along with other desirable quantitative and quality traits revealing thereby these genotypes can be directly used after multi-location testing.
