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.
