中文摘要：

为探讨”熵权法”用于高丹草种质资源综合评价中各因素的赋权，以熵权赋权法、灰色系统理论中的灰色关联度法以及聚类分析对14个高丹草新种质资源材料，从形态指标、品质指标和产量等方面进行了综合评价。结果表明：综合表现较好的品系pb6、pb5、pb2、pb1；表现中等的为pb7、pb3、pb13、pb4、pb10；表现较差的为pb12、pb14、pb8、pb9和pb11。聚类分析也得到相同结果，说明基于熵权赋权法的灰色系统理论可以在高丹草种质资源综合评价中应用。

英文摘要：

Entropy weight - based gray systematic theory was used to evaluate 14 sorghum x sudan grass new lines according to their morphological traits, quality index and productivity. The results of integrated evaluation showed that pb6, pbS, pb2 and pbl were the best than other lines in performance, pb7, pb3, pb13, pb4 and pbl0 were average in agronomic traits; pb12, pb14, pb8, pb9 and pb11 were the worst among tested lines. At the same time, the result of cluster analysis was consistent with that of gray systematic analysis. This indicated that entropy weight - based gray systematic theory can be used in integrated evaluation in sorghum x sudan grass zermplasm.
