摘要
应用灰色关联度法对来自内蒙古13个地区的20份野生扁蓿豆(Medicago ruthenica)材料在内蒙古呼和浩特市的栽培生产性能进行综合评价,采用株高、生育期、株高生长速度、干鲜比、鲜草产量、干草产量和种子产量等指标建立评价模型,综合评价各材料的栽培生产性能。结果表明,栽培生产性能表现较好的材料有来自锡林郭勒盟灰腾梁的M-4、通辽市的M-8、锡林郭勒盟西苏旗的M-5和通辽市的M-6,而来自包头市达茂旗的M-20、乌兰察布市四子王旗的M-19、锡林浩特市的M-3和赤峰市的M-10栽培生产性能较低。根据各性状指标的权重比较种子产量所占的权重为株高>生育期>株高生长速度>干草产量>鲜草产量>干鲜比。
In this paper, the method of gray correlation was used to perform the comprehensive evaluation of 20 wild Medicago ruthenica materials from 13 regions of Inner Mongolia. Plant height, growth dura- tion, growth rate of plant height, D/W-Ratio, wet matter yield, dry matter yield and seed yield were used as indicators to constructed the model to evaluate the production performance of various materials. The results showed that M-4 from Huitengliang County, M-8 from Tongliao City, M-5 from Xisu County and M-6 from Tongliao City showed relatively better production performance. In contrast, M-20 from Damao County, M-19 from Wulanchabu Siziwangqi, M-3 from Xilinhot and M-10 from Chifeng City showed low production performance. The weight of each trait indicator were in the following order, plant height growth duration：〉growth rate, dry matter yieldS〉wet matter yieldeD/W-Ratio.
