植物亲缘远近虽与杂交亲合性有关,但不是绝对的。例如蔷薇科和禾本科,不仅种间能自由组合,而且属间杂种也不少见,更有甚者,莎草科还有亚科与亚科之间自由杂交的杂种。梨亚科各属间形成属间杂种的有:山楂花楸、梨山楂、梨榅桲及花楸梨等。1978年以来,我们探索苹果×杏、桃,在蔷薇科亚科间进行杂交。开始便多配组合,多杂交花朵,从中筛选亲合力强的苹果品种作母本,用常规杂交法去雄 Although phylogenetic relationship with hybrid affinity, but not absolute. For example, Rosaceae and Poaceae, not only the species can be freely combined, but also interspecific hybrids are not uncommon, what is more, Cyperaceae subfamily and subfamily of hybrids between free hybrids. Pear subfamily genus intergeneric hybrids are: hawthorn Sorbus, pear hawthorn, pear 榅 桲 and rowan pear and so on. Since 1978, we have explored apple × apricot, peach and hybridized between Rosaceae subfamilies. The beginning of the combination will be more, more hybrid flowers, from screening strong affinity Apple varieties as the female parent, using conventional hybrid methods to male
