摘  要:
报道了南瓜属 3个主要栽培种——中国南瓜、印度南瓜和美洲南瓜种间杂交不亲和性和杂种表现 ;同一杂交组合正反交亲和力差异大多数表现显著或极显著 ,少数不明显 ,杂种 F1代花粉育性不受杂交亲和力影响 ;同一栽培种不同品种与另一种杂交亲和力有很大差别 ,子一代花粉育性与杂交亲和力有关 ;并讨论了影响杂交亲和性有关因素和不亲和实质

摘  要:
This paper reported the incompatibility and hybrid performance of the interspecific sexual hybridization among the three main cultivare of Cucurbita i.e. C.moschata D, C.maxima D and C.pepo L.Significant or very significant variations of compatibility were found between most of the reciprocal cross in the same cross combination,but some combinations had less variation.The pollen fertility of F 1 hybrids was not effected by its hybrid compatibility.Different varieties of same cultivar have significant variance in the hybrid compatibility when crossing to other cultivar.The pollen fertility of their F 1 hybrids was related to their cross compatibility;Some factors effecting the cross compatibility and the essence of incompatibility were also discussed in the paper.
