Abstract
Abstract Parents, F1, F2 and backcross generations of a cross between a Cucumis sativus L. gynoecious inbred, GY 14, and a selection of Cucumis sativus var. hardwickii (R.) Alef. were evaluated for several horticultural characteristics. Generation means were significantly different for all characteristics, and were analyzed using an unweighted least squares procedure. An additive-dominance model accounted for most of the variation among generations for fruit weight per plant, lateral number, main stem and mature fruit length, diameter and length/diameter ratio. Additive × additive epistasis was involved in the variation among generations for fruit number per plant. Heterois above the high-parent was observed for fruit weight per plant and the main stem length, dominance was the major contributing factor to variation for these traits. F1 deviation from mid-parent was observed for lateral number.
