利用70对扩增产物稳定的SSR引物对23份高淀粉玉米自交系的遗传多样性进行研究。结果表明，23份高淀粉自交系被划分为4个类群，高淀粉玉米自交系中含Reid种质的数量12份，含国内种质6份，含有Lancaster种质和PB种质的高淀粉玉米自交系最少。在聚类分析的基础上对高淀粉玉米育种进行初步探讨。

Seventy SSR primers were used to detect genetic diversity among 23 high-starch inbred lines. These inbred lines could be classified into 4 subgroups. Twelve high-starch inbred lines were included in Reid germplasm and 6 high-starch inbred lines were included in domestic germplasm, There are less high-starch inbred lines in Lancaster germplasm and PB germplasm respectively. Some strategies for the genetic improvement of starch content in maize was discussed briefly in the paper.
