| 摘 要： | 以黄瓜属(Cucumis)野生种(C. hystrixChakr. )为母本,以栽培黄瓜(C. sativusL. )北京截头为父本,通过远缘杂交导入外源种质,结合多代回交、自交获得黄瓜新种质7012A。将7012A与美国威斯康辛大学选育的雌性系黄瓜(7011A)杂交获得F1,与亲本及美国推广加工黄瓜品种进行品种比较试验,结果表明:F1 具有超亲优势,结瓜整齐,营养价值高,加工品质良好。植株长势强,主侧蔓均有结瓜能力,主蔓结瓜为主,后期产量高。

| Abstract: | A new pickling cucumber line 7012A was developed through interspecific hybridization of cultivated cucumber Beijingjietou with the Cucumis wild species C. hystrix and subsequent backcrossing of the hybrid to cucumber and selection from the selfed progenies. This line was used to cross with an elite American pickling cucumber line (7011A) from the University of Wisconsin to produce F 1. The results indicated that the F 1 has significant heterosis over its parents in yield and growth vigor. The plants set uniform fruits with good quality. Fruits could be set on both the main and lateral branches. It has highest late yield and its total yield was higher than all the other cultigens tested. |
