Clustering results showed that the clusters were not corresponding to heterotic groups and pedigrees,which suggested that the A-PAGE of seed storage proteins might not be a good method for large-scale analysis of genetic diversity and heterotic grouping in maize germplasm.

利用盐溶蛋白多态性完成的聚类分析结果和自交系系谱及杂种优势群之间没有明显的对应关系，表明储藏蛋白A-PAGE方法对于大规模玉米种质资源的遗传多样性分析和类群划分可能存在局限性。

Heterosis is based on the heterozygosity of heterozygotic genotypes.

Subclones of the hybrid 741 took on a high insect-resistant identity to the larvae of leaf pests such as Clostera anachoreta Fabricius, Lymantria dispar Linnacus, Hyphantria cunea Drury ect., and the mean death rate of the grubs were all above the 85%, furthermore, the grubs' growth which survived could be restrained and the growth rate was reduced so that they couldn't tie cocoons as the usual.

项目简介：转双抗虫基因741杨是将部分改造BtCryIAc 基因与慈菇蛋白酶抑制剂基因，通过农杆菌介导法转化了优良白杨杂种741杨，并获得了一批具有高抗虫性无性系，对舞毒蛾和杨扇舟蛾，美国白蛾等鳞翅目幼虫死亡率达85%以上，并能抑制存活幼虫的发育，使其不能正常化蛹。

He published prolifically on hybrid sterility, developmental rates, enzyme polymorphisms, genetic responses to environmental change, and behavioral phenomena, such as dispersion rates.
