Aimed at the arising problems such as the cross-incompatibility and hybrid's sterility during distant hybridization of fruit trees, effects of different treatments on cross-compatibility of distant hybridization in stone fruits were studied based on the former studies, then physiological and biochemical changes during hybridization between plum and apricot were primarily discussed, and rescue and culture system of hybrids' embryos were also conducted, further the genetic variation and principle between the hybrids and their parents were analyzed and methods of identification of hybrids were established.

针对果树远缘杂交过程中存在的杂交不亲和性及杂种不育性等问题，在前人研究的基础上，研究了不同处理对核果类果树远缘杂交亲和性的效应，并探讨了李、杏属间杂交过程中发生的生理生化变化以及花粉与柱头的互作，建立了李、杏属间远缘杂种的胚培养技术体系，建立了杂种鉴定检测方法，并分析了杂种后代与其父母本之间的遗传变异及规律，最终将一批远缘杂交新种质定植于大田，同时对自然界存在的杏梅种质资源进行了RAPD分析。
