Sudhanshu Mishra, Satrughan Pandey, Navin Kumar, VP Pandey and T Singh
Observations were recorded on parents and F1 for 12 traits viz. days to first male and female flower anthesis, node number to first male and female flower appearance, days to first fruit harvest, vine length (m), number of primary branches per plant, fruit length (cm), fruit circumference (cm), fruit weight (kg), number of fruits and fruit yield per plant (kg). Parent NDBG-744, Pusa Naveen and NDBG-707 for number of fruits and yield per plant, for number of fruits and yield along with earliness parent NDBG-707 and Pusa Naveen, for small fruit NDBG-749-2 and Pusa Naveen, were found good general combiners. Combining abilities coincides with per se performance. Additive and non additive gene action with over mean degree of dominance indicated predominant role of non-additive gene action in the inheritance of most of the traits. Asymmetrical distribution of genes showing dominance with more proportion of dominant gene than recessive one were detected for all the trait’s no major gene group were involved in the inheritance of all the traits studies.
