杂交育种是萝卜育种的重要途径,而亲本的选择是育种成败的关键,为了提高育种效率,增加组合选配的预见性,本试验对5个萝卜亲本的3个数量性状进行了配合力分析,以供萝卜育种和杂种优势利用提供依据。材料和方法 1989年以来以大红袍(F)、灯笼红(A)、王兆红(E)、磨盘(S)和花叶农大红(花)等品种为亲本,采用完全双列杂交半轮配法,配制10个组合,1989年秋选择母根进行窖贮,1990年4月中旬种植母根杂交制种,7月20日播种于露地,试验采用随机区组法,双行区,小区面积6
Hybrid breeding is an important way of radish breeding. The selection of parents is the key to the success or failure of breeding. In order to improve the breeding efficiency and increase the predictability of combination selection, we analyzed the combining ability of three quantitative traits of five radish parents, To provide the basis for radish breeding and heterosis utilization. Materials and methods Since 1989, Dahongpao (F), lantern red (A), Wang Zhaogong (E), grinding disc (S) , The preparation of 10 combinations, the autumn of 1989 selected parent root pit storage, mid-April 1990 planting seedling hybrids, July 20 sowing in the open field, the trial using random block method, double row area, plot size 6
