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。

The results show that, Pian Nui can form the structure of SC in autosomes of a few primary spermatocytes and has more synaptonemal abnormalities.

根据研究结果，作者认为牦牛与普通牛在部分常染色体和性染色体上的差异，使犏牛的同源染色体不能很好地配对形成SC ，是导致不育的主要原因之一。

Four male sterile lines and nine restorer lines were used in incomplete diallel crosses to analyze the genetic effects of appearance quality traits in japonica hybrid rice by using the genetic model and analysis method for quality traits of endosperms in cereal crops.

以宁 6 7A等 4个粳型不育系与 K172 2等 9个粳型恢复系进行不完全双列杂交，采用禾谷类作物胚乳品质性状的遗传模型及其分析方法，对粳型杂交稻稻米外观品质性状进行了遗传研究。

The increase of soluble sugar was not equal to the starch in lodicules which was disintegrated during flowering. The soluble sugar was mainly transferred from other in maternal plants, but mainly from starch's disintegration in paternal plants.

开颖过程中，浆片中可溶性糖增加量不等于其所含淀粉水解生成量，不育系浆片中可溶性糖的增加较多地依靠外部输送，恢复系则主要靠浆片中淀粉的水解。
