An experiment was conducted at Horticulture Research Station, Devihosur, Haveri during Kharif 2008. Threepopulations of the okra viz, biparental F2, and single cross F2, and double cross F2 were developed using BH-1, BH-2, and BH-3, and these populations were evaluated in 2009. The objective was to study the extent of variability and relationship between various economically important traits for the purpose of genetic improvement. The trial was laid out in a Randomized Complete Block Design (RCBD) with two replications. The results obtained showed genotypic coefficient of correlation showed more significant relationship between the pairs of characters, meaning that, these characters are more related genotypically and selection strategy for yield improvement should rely on average fruit weight (0.859), number of fruits per plant (0.929), 100 seed weight (0.871), No of branches per plant (0.916), during selection process in segregating populations, as these characters exhibited positive significant association with fruit yield per plant.
