Abstract:
Gene action and combining ability for some traits were analyzed in 49 crosses along with their 14 parents in randomized complete block design consist of three replications. All the characters under investigation showed high significant difference for genotypes, general and specific combining ability. The sca effect for all the character greater than GCA effects that showed variance due to non-additive gene action for all the characters. The parent DBG-35 is good combiner for node at which first female flowers appear, number of fruits per plant, days to last harvest and vitamin-C. The parents Punjab Kareli-1, Arka Harit, Pant Karela were good combiner for number of fruits per plant, total and marketable yield, and days to last harvest. However, Punjab-14, PAUBG-4, PAUBG-13, and Arka Harita were good combiner for total sugar. The cross PAUBG-4 x Pant Karela was recorded highest significant sca effect for day to first female flowers appear, number of fruits per plant, fruit weight, total and marketable yield. The hybrid Punjab-14 x PAUBG-20 and PAUBG-13 x VR-1 were showed highest significant for SCA effects for vitamin-C and total sugar, respectively.
