The experiment was conducted with 120 treatments (28 F1s, 28F2s, 28B1s and 28B2s populations) developed through diallel technique excluding reciprocals along with 8 parents viz., AB-2, AB-1, KS-312, BO-2, P-7, VRO-3, VRO-5 and PK in a randomized block design with three replications at the Research Farm of the Department of Vegetable Science, C.S. Azad University of Agriculture and Technology, Kalyanpur, Kanpur during Kharif 2006. The observations was recorded on 20 randomly selected plants for 10 quantitative traits namely, days to flowering, height of plant (cm), number of branches per plant, number of first fruiting node, number of nodes per plant, length of fruit (cm), width of fruit (cm), number of fruits per plant and yield per plant (g). The phenotypic and genotypic correlation coefficients were workout to measure the association among the quantitative traits. Correlation coefficient for fruit yield per plant had positive and significant association with number of nodes per plant, length of fruit and number of fruits per plant at both genotypic and phenotypic level in all the generations.
