Estimates of gene action in cucumber (Cucumis sativus L.)

Estimates of gene action in cucumber (Cucumis sativus L.)

2007

A:PS

A study of fifteen F1 hybrids of cucumber (Cucumis sativus L.) in a diallel set involving six parents showed over-dominance and low narrow-sense heritability for earliness, number offruits per plant and total yield per plant. Components of additive gene actions were significant for fruit weight, fruit length and fruit diameter. The breeding methods like pure line selection for the above characters which have additive gene effects at significant levels and heterosis breeding which having predominant role of non-additive gene action, may be exploited for improvement of these traits.
