| 摘 要： | 选取南瓜属2个主要栽培种美洲南瓜和印度南瓜共12个品种的多代自交材料进行远缘杂交,选配了正反交组合共72个,研究其正反交的亲和性差异,不同材料间的亲和性差异以及杂种后代的表现。结果表明:美洲南瓜与印度南瓜进行种间杂交,美洲南瓜只适合作母本、印度南瓜只适合作父本;其正反交的亲和性不同,表现在坐果率、有胚果实率以及有胚率等方面的差异;远缘杂种的不育性、不稔性与杂交亲和性有关;并讨论分析了用印度南瓜改良美洲南瓜的可行性。

| Abstract: | In this experiment,12 self-line materials of two main cultivars in Cucurbita were crossed. There were 72 reciprocal cross combinations. The compatibility difference between reciprocal crosses and different materials,and the features of hybrid progenies were studied. The results showed that C. pepo L. was only suitable to be female parent and C. maxima D. was only suitable to be male parent in carrying out interspecific hybridization between C.pepo L. and C. maxima D. The variability of crossing compatibilit... |
