| 摘 要： | 试验利用7个黄瓜自交系，按Griffing完全双列杂交第二套方案配制28个杂交组合，比较了12个农艺性状、2个生理性状和3个品质性状等数量性状的杂种优势。对3个质量性状遗传规律进行了初步研究，结论如下：有刺型对无刺型呈显性。有瓜把型对无瓜把型呈显性，长瓜把型对短瓜把型呈显性，单株前期产量和单株总产量、可溶性固形物、维生素C表现出较高正向的杂种优势：第一雌花节住、单瓜重平均杂种优势值表现出一定程度的负向杂种优势。

| Abstract: | Seven inbred lines of cucumber were used in this.The combining ability and genetic parameters of twelve agronomic characters and genetic laws of two physiology characters and three qualitative characters were studied with a design of Gfiffing complete diallel cross method two.Heterosis of quantitative characters including three nutritional quality characters and twelve agronomic characters were also analysed.The main results are showed below： The spire types were dominant over the types without spire;The fruit end types were dominant over the types without fruit end;The long fruit end types were dominant over the short fruit end types.The average heterosis of yield per plant at early stage, yield per plant,solid content and VC content were highly positive conspicuous. The average heterosis of first pistillate flower bearing node and weight per fruit were lowly negtively conspicuous. |
