    摘要:

    本试验对70份云南割手密血缘F1代创新种质材料8个工农艺性状进行了因子和聚类分析。因子分析中8个公因子保留前3个公因子,其累计贡献率达79.35%。第1公因子中载荷值较大的是单产、含糖量、公顷有效茎数、出苗率和分蘖率等性状;第2公因子中起主导作用的性状是茎径和株高两个产量因子;第3公因子只有11月理论蔗糖分起主导作用。以70份创新材料3个公因子的因子得分为指标,采用系统聚类中的最长距离法进行系统聚类分析。在遗传距离2.4处,参试材料被聚为十类,其中占参试材料总数的38.6%的第Ⅰ、Ⅳ、Ⅶ、Ⅷ、Ⅹ五类材料,表现高产;占参试材料82.8%的第Ⅰ、Ⅱ、Ⅳ、Ⅴ、Ⅵ、Ⅶ、Ⅸ七类材料,表现高糖,特别是其中占参试材料52.8%的Ⅰ、Ⅳ、Ⅴ、Ⅵ四类材料,11月理论蔗糖分均高于12%;占参试材料总数30%的第I、Ⅳ、Ⅶ三类材料,表现高产、高糖。这个分类结果为有针对性的利用这些创新种质材料培育高产、高糖创新亲本提供了科学依据。

    Abstract:

    Eight characters from 70 innovated germplasm materials blood F1 of Saccharum spontaneum L. were processed by factor and cluster analysis. Results of factor analysis showed that the top three common factors were ratained in 8 common factors and the cumulative contribution rate reached 79.35%.Yield, sucrose content in cane,stalk number,emergence rate and tillering rate owned higher loading values in the first common factor. The stalk diameter and plant height played leading roles in the second common factor,;and only sucrose content in cane played a leading role in the third one. The variance scores of the 70 innovated materials of the top three common factors were used for comprehensive cluster analysis with the longest distance method. At the genetic distance 2.4, the materials could be divided into 10 groups,in which five groups i.e.Ⅰ,Ⅳ,Ⅶ,Ⅷ andⅩ showed the characteristic of high yield, accounting for 38.6% of the total tested materials. The groupsⅠ,Ⅱ,Ⅳ,Ⅴ,Ⅵ,Ⅶ and Ⅸ showed the characteristic of high yield,accounting for 82.8% of the total, especially the groupsⅠ,Ⅳ,Ⅴand Ⅵ,which sucrose content in cane was higher than 12% ,accounting for 52.8% of the total. The groupsⅠ, Ⅳand Ⅶ showed the characteristic of high sugar and high yield, accounting for 30% of the total.The classification results provide a scientific basis for targeted utilization of these innovated germplasm materials to breed the parents with high yield and high sugar characteristics.
