亲本选择是杂交育种工作的关键。亲本选配主要根据性状互补,亲缘关系及地理关系相距较远;种性差异大等原则。但由于构成产量因素的复杂性及其品质性状大多为数量性状,在实际操作中不易符合这几条原则。因而为获得强优组合不得不配制大量的组合进行筛选,盲目性较大。作者于1983—1984年间,利用聚类分析法选择香菇杂交亲本并以品比试验验证预测的结果。现报告如下:
Parent selection is the key to hybrid breeding. Parental matching is mainly based on complementary traits, genetic relationship and geographic distance; However, due to the complexity of producing factors and their quality traits are mostly quantitative traits, it is not easy to comply with these principles in practice. Therefore, in order to obtain strong combination, a large number of combinations have to be prepared for screening, and the blindness is relatively large. The author used the method of cluster analysis to select the parents of Mushroom during 1983-1984 and verified the results by the ratio test. The report is as follows:
