摘要
基于熵权赋权法、运用灰色系统理论中的灰色关联度法对10个燕麦品种从生产性能、品质以及抗倒伏性、抗病性等方面进行了综合评价。结果表明,综合表现较好的有青永久118、青永久474及青永久94;表现一般的有青永久478、青永久81和青引1号;表现最差的是青永久136、CNC、黄燕麦和青永久12。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用于燕麦种质资源的综合评价。
Entropy weight-based gray systematic theory was used to evaluate 10 oat （Arena sativa L. ） varieties according to their productivity, quality, lodging and disease resistance. The results of integrated evaluation showed that Qingyongjiu118, Qingyongjiu474 and Qingyongjiu94 were better in performance; Huangyanmai, Qingyongjiu 136, Qingyongjiu 12 and CNC were poorer; Qingyongjiu478, Qingyongjiu81 and Qingyin No. 1 were in the middle. 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 of oat （Arena sativa L.） germplasm.
