Abstract: The present investigation was conducted to know the diversity among the F₁ hybrids developed through diallel mating design with the using 8 diverse parents for quantitative and qualitative traits. The study was conducted with the field evaluation of 28 F₁ hybrids and 8 parents during two consecutive years. The perusal of results indicated that the high genotypic coefficient of variation as well as phenotypic coefficient of variation recorded for fruit circumference, average fruit weight and number of fruits per plant, marketable yield, unmarketable yield and yield per plant during both the years. The present investigation indicated that the high heritability in narrow sense observed for fruit length and fruit circumference during both the years. Whereas, plant height and dry matter content were recorded high heritability in narrow sense during Y₁. The that high heritability (h²ns) coupled with high genetic advance as per cent of mean were observed for fruit length and fruit circumference, indicating thereby that these traits were less influenced by environment and were mainly under control of additive genes.
