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 viz; days to flowering, height of plant (cm), number of branches per plant, number of first fruiting node, number of nodes per plant, length of internode(cm), length of fruit (cm), width of fruit (cm), number of fruits per plant and yield per plant (g). Heritability estimate in narrow sense was high for number of branches per plant and moderate for other characters were found in both the generations. The studies based on genetic advance showed that an advancement of 8.9 g in fruit yield per plant was observed from single cycle of selection at K = 2.06. The probable genetic gain was high for number of branches per plant, length of inter node and number of first fruiting node.
