| 摘 要： | 谷子形态水平、染色体水平、生化水平及DNA水平上遗传多样性的研究进展表明,谷子在不同生态环境下栽培,适应性结果导致了形态学性状和农艺性状的较大变异;染色体核型和带型的分析显示不同谷子品种在核型组成、核型分类方面存在分化;生化水平上,谷子的品质含量表现了丰富的多样性,蛋白质标记的指纹图谱也存在一定的差异;分子水平上,谷子种内存在一定的遗传多样性,分子标记是研究谷子遗传差异最有效方法。本文也对谷子育种如何有效利用遗传多样性研究的信息进行了探讨。 |

| Abstract: | In this paper, study advances in genetic diversity of foxtall millet were summarized from different aspects concluding morphology, chromosome, biochemistry and DNA. Results showed that there were large variation in morphologic and agronomic characters with cultivating in different ecological environments, there were differentiation in chromosome analysis, there were diversity in quality and protein fingerprint, there were also diversity in DNA and DNA analysis was the most available method in genetic diversity study. In the paper, some problems how to use the information of study on genetic diversity in foxtail millet breeding were also analysed. |
