摘要： 采用灰色关联度分析法对8个甜高粱(Sorghum dochna)品种的9个性状进行综合评价。结果表明:在青海东部农业区表现较好的甜高粱品种有九甜杂三、大力士、超级放牧者,而吉甜3号和辽甜1号的生产性能较差。各项指标的权重大小顺序为单株干质量>分蘖数>鲜干比>鲜重产量>主茎粗>单株鲜质量>出苗率>株高>绿叶数,研究结果可为该地区甜高粱的引种及推广提供科学依据。

关键词: 甜高粱, 生产性能, 灰色关联度分析, 评价

Abstract: The grey correlative degree analysis was applied to comprehensively evaluate the growth performance of 8 sweet sorghum varieties by nine characteristics. Three varieties including Jiutianzasan, Hunni green and Super herder performed well, whereas Jitian 3 and Liaotian 1 had relatively low suitability in the eastern agricultural region of Qinghai province. The order of weight index in the grey correlation analysis was plant dry weight>tillers number>fresh to dry ratio>fresh yield>stem diameter>plant fresh weight>emergence rate>plant height>green leaf count. This result will provide a scientific evidence for introducing and extending sweet sorghum in the region.

Key words: Sweet sorghum, Production performance, Grey correlative degree analysis, Evaluation
