오이의 몇가지 形質에 關한 Diallel 分析

Diallel Analysis of Several Characters in Cucumbers, Cucumis sativus L.

Significant heterosis was recorded from hybrids in a seven-parent half diallel of cucumber for node of first female flower (16.67%**, significant at the l% level), number of female flowers (-35.09%**), female/male flowers (-44.40%**), early weight/plant (22.86*, significant 5% level), total fruit/plant (12.28%*) and total weight/plant (13.86%*). Both additive effects (GCA) and nonadditive effects(SCA) were important in explaining variability among F₁’s for femaleness characters and weight/fruit, but the former was more important for early fruit/plant than the latter. Nodes of first female flower among a few femaleness characters appeared to be a highly heritable character conditioned by predominantly additive polygenic system with partial dominance for high nodes.
