摘　　要：以50个李、杏、杏李品种为试材,根据最大单果重、平均单果重、可溶性固形物、可溶性糖、可滴定酸和维生素C含量等6个指标筛选出"味帝""味王""味厚""恐龙蛋""苹果李""风味皇后""风味玫瑰""灰子李""兰州大接杏""银香白"和"平顶香"等11个果实较大、品质优良的品种作为杂交亲本的育种材料,并结合11个优良品种的S基因型和花期,从110对杂交组合中最终筛选出了55对可行的种间杂交组合,为李亚科远缘杂交新品种创制提供了重要的理论基础和实践指导。Eleven elite cultivars, ＇ Weidi ＇, ＇ Weiwang＇, ＇ Weihou ＇, ＇ Konglongdan＇, ＇ Pingguoli ＇, ＇ Fengweihuanghou ＇, ＇ Fengweimeigui ＇, ＇ Huizili ＇, ＇ Lanzhoudajiexing ＇, ＇ Yinxiangbai ＇ and ＇ Ping- dingxiang＇ were selected as breeding materials from 50 cultivars of plum, apricot and simonii based on the biggest single fruit weight, average single fruit weight, the content of soluble solids, total sugar, total acid and Ve. 55 combinations were screened from ll0 crosses based on the S-genotypes and flowering time of these 11 cultivars , which provided important theoretical basis and practical guidance for the breeding of interspecific hybrids of plum.
