玉米遗传多样性研究方法初探

Preliminary Research Methods of Genetic Diversity of Maize

从形态学、细胞学和分子3种水平上概述了遗传多样性在玉米方面的研究,总结了形态标记、染色体带型标记、同工酶标记以及DNA分子标记在玉米遗传多样性研究上的应用。为了更好地揭示遗传多样性,多种标记方法应该有选择地结合起来,以便为玉米育种工作提供参考和依据。

This paper overviewed the studies of genetic diversity in maize from morphological, cytological and molecular levels, and summarized the applications of morphological markers, chromosome banding pattern markers, isozyme markers and DNA molecular markers on genetic diversity in maize. In order to better reveal the genetic diversity of maize and provide reference and basis for maize breeding, multiple marker methods should be combined selectivly.
