An experiment was conducted to study the combining ability analysis using six parental genotypes and thirty hybrids of pumpkin obtained through full diallel analysis for yield and its attributing traits. The mean sum of square due to general combining ability (gca) and specific combining ability (sca) were significant for nodes to first female flower, days to harvest, fruit weight, fruit length, fruit diameter and number of seeds per fruit. The ratio of gca/sca was less than one for the character nodes to first female flower indicated the preponderance of dominance expression. | Combining ability studies in pumpkin (Cucurbita moschata Duch ex Poir)
