| 摘 要： | 【目的】对64份甘蔗属割手密种(Saccharum spontaneum)云南割手密82-114(云南82-114)的F1代进行综合评价和分类,为进一步筛选和利用优良种质提供依据。【方法】采用灰色育种理论的灰色关联度对云南82-114血缘F1代的9个性状进行综合评价与分类。【结果】在64份材料的灰色关联度排名中,排名居前10位的分别为云瑞08-155、云瑞08-52-1、云瑞08-147、云瑞08-157、云瑞08-197、云瑞08-105、云瑞08-111、云瑞08-96、云瑞08-52-2、云瑞08-83,超过对照ROC22的材料有5份,超过对照粤糖93-159的材料有10份,其余的54份材料均未超过两对照。依据材料间灰色关联度建立三角矩阵,取等价截距λ=0.890时,可将材料分为22个类型,大部分材料可单独聚为一类。灰色关联度评价和聚类分析结果表明,云瑞08-155、云瑞08-52-1、云瑞08-147、云瑞08-157、云瑞08-197、云瑞08-105、云瑞08-96等7份材料可作为杂交利用的重点材料。【结论】灰色关联度综合评价结合聚类分析对材料的高效筛选和杂交利用具有较明确的指导作用,是一种方便、简捷的评判方法。

| Abstract: | Objective]The present study was conducted to evaluate and classify 64 accessions of S. spontaneum Yunnan 82-114 F1 in order to provide references for screening improved germplasm resources. Method]The gray correla-tion degree based on the theory of gray breeding was put to use in comprehensive evaluation and classification of nine traits of 64 generation F1 derived from Yunnan 82-114. Result]The results showed that the top 10 materials in gray cor-relation degree ranking of all materials were as fellows: Yunrui 08-155, Yunrui 08-52-1, Yunrui 08-147, Yunrui 08-157, Yunrui 08-197, Yunrui 08-105, Yunrui 08-111, Yunrui 08-96, Yunrui 08-52-2, Yunrui 08-83. There were five materials exceeding the control variety ROC22 and ten materials over YT93-159 in gray correlation degree ranking , respectively. While the other 54 materials did not exceed both of two control varieties. The triangle matrix was constructed by using gray correlation degree among the 64 materials. The 64 materials were classified into 22 types when the equiva-lence matrix λ was 0.910, and most of them could be classified into a type by oneself. The results of gray correlation de-gree evaluation and cluster analysis indicated that, Yunrui 08-155, Yunrui 08-52-1, Yunrui 08-147, Yunrui 08-157, Yunrui 08-197, Yunrui 08-105 and Yunrui 08-96 could be used as key materials for cross breeding. Conclusion]Com-bining gray correlation degree evaluation with cluster analysis is a convenient and forthright evaluating method , and is very available on guiding high-efficient screening , crossing and utilization of sugarcane germplasm resources. |
