苜蓿品种辐射敏感性的模糊聚类分析

Fuzzy Clustering Analysis for the Varietal Radiosensitivity of Lucerne Varieties.

将模糊数学中的Ｆｕｚｚｙ聚类方法首次应用于牧草辐射育种，对苜蓿品种辐射敏感性作了Ｆｕｚｙ聚类分析，将２５个苜蓿种和品种分为极敏感型、敏感型、中间型、迟钝型和极迟钝型五类。研究还表明，Ｆｕｚｙ聚类分析作为一种科学的、定量化的分类方法，应用于牧草品种辐射敏感性强弱的划分是客观的、全面的和可行的。

Fuzzy clustering classfication to the varietal radiosensitivity of Lucerne (Medicago) was carried out in this study. According to their responses to the radiation of gamma rays, 25 lucern species and varieties were classified into five groups: higher sensitive, sensitive, intermediate response, resistant, higher resistant. The research presents a new approach for the classification of the varietal radiosensitivity of herbage plants, and the result is valuable for choosing the adequate irradiated materials so as to enhance the mutagenic efficiency in lucerne breeding. The reliability and abvantage of the Fuzzy clustering classification for varietal radiosensitivity were briefly discussed.
