摘要
为了评价16个引进品种的适应性,为东北寒冷干旱地区苜蓿引种和推广提供科学依据,也为苜蓿引种适应性鉴定和评价提供可选择的性状指标,试验在黑龙江西部地区应用灰色关联度法对16个引进苜蓿品种的生长适应性性状进行了分析,并建立了品种适应性综合评价模型。结果表明:在该地区引种适应性表现较好的苜蓿品种有WL343HQ、俄罗斯苜蓿,生产性能相对较差的品种为德宝、WL903;各项指标的权重大小顺序为粗蛋白>叶长>叶宽>茎粗>株高>再生速度>主根长>鲜干比>根颈直径>单株干重>侧根数目>茎叶比>根系鲜重。
To evaluate the adaptability of the sixteen introduced varieties, and provide a scientific basis for the introduction and promotion of alfalfa in the cold arid regions of the Northeast, and also to provide selectable trait indexes for the identification and evaluation of the introduction adaptability of alfalfa. The grey correlation analysis was used for analyzing the adaptability traits of growth for sixteen introduced varieties of alfalfa, and then the model of comprehensive evaluation for the variety adaptability was constructed in the western area of Heilongjiang province. The results showed that the introduction adaptability of the alfalfa varieties including WL343HQ and Russian alfalfa performed well in the area, whereas the productive performance of the alfalfa varieties including Debao and WL903, was relatively low. The weight of the each index in the descending order was as follows ： crude protein, leaf length, leaf width, stem thickness, plant height, regrowth speed, length of taproot, ratio of fresh to dry, root collar diameter, dry weight per plant, number of lateral root, ratio stem to leaf, and fresh weight of roots.
