Heterosis and combining ability in cucumber (Cucumis sativus. L.)
Author(s): N Malav, Mohan lal yadav and IB Maurya
Abstract: The present study on heterosis and combining ability for fruit yield and its components was carried out in a set of 42 F1 hybrids of cucumber obtained from a full diallel involving three gynoecious and four monoecious parents at College of Horticulture and Forestry, Jhalawar during summer 2014. The results revealed that there was significant differences among the parents and hybrids for most of the characters except for days to fruit maturity from anthesis, fruit length, fruit diameter, fruit weight, days to fruit harvesting and total soluble solids indicating the importance of both additive and non-additive gene action. Among the parents, Poinsette was found to be the good general combiner for fruit length, fruit diameter, fruit weight, number of branches per plant and vine length at final stage. Hilton and Isatis was also found good general combiner for yield per plant. The cross combination Poinsette x JWRC-1, Hilton x Swarna Sheetal and Isatis x Swarna Agetiwere found to be good specific combiner for fruit yield and its related contributing characters. Hilton x Swarna Sheetal was found heterosis yield per plant ranged from -36.10 percent to 25.78 percent over mid parent -41.26 percent to 17.87 percent over better parent and -39.74 percent to 15.99 percent over standard parent.
