Title: Exploiting Heterosis for Yield and Horticultural Traits in Cucumber (Cucumis sativus L.)
Abstract: Hybrids in cucumber have several well known advantages over the open-pollinated varieties. To find out more appropriate combinations for developing superior hybrids in cucumber, the crosses among eight parents (including two gynoecious lines) were attempted in half diallel fashion. Twenty-eight F1s, eight parents and one check were grown in a Randomized Block Design with three replications at two different locations viz. Nauni (L1) and Chambaghat (L2). Sufficient genetic diversity among parents and F1s for all the traits infers the scope of improvement through selection in the parental material. Among the parents, G2 took minimum value for number of days to first female flower appearance, node number of first female flower and days to marketable maturity. Heterobeltiosis and standard heterosis for earliness were maximum in EC173934 x LC-40 and G2 x Gyn1, respectively. The cross K-90 x G2 exhibited maximum heterobeltiosis and standard heterosis for yield and number of fruits.
