Abstract

Twelve F1 hybrids of cucumber derived from a topcross involving twelve monoecious parents and a gynoecious parent (EC 709119) were evaluated in randomized block design (RBD) with three replications to study heterosis over mid and better parents. Significant heterosis was observed for all the characters studied except average fruit weight. The hybrids EC 709119 x IC 538155 followed by EC 709119 x IC 527427, EC 709119 x IC 538186 and EC 709119 x IC 410617 exhibited high heterobeltiosis for fruit yield and fruits per plant. These hybrids can be advanced for further testing for commercial exploitation of hybrid vigour..
