摘要: [目的] 在甘肃省酒泉地区筛选出符合当地生产条件的优质高产苜蓿品种。[方法] 在甘肃省酒泉市肃州区上坝镇播种来自不同生态区的57份紫花苜蓿材料,对现蕾初期的农艺性状和产量进行多样性分析及综合评价,并进行农艺性状间相关性分析、主成分分析,进行聚类分析和隶属函数综合评价。[结果] 57份紫花苜蓿材料分为4类,即产量最低及综合排名最低的材料分为第一类;将产量及综合排名最高的分为第二类;产量较高但其他指标较差的材料分为第三类;产量和综合排名属于中间的分为第四类。[结论] 在该地区种植当年综合评价较好的紫花苜蓿品种为中苜3号、北方SLT、SR4030、WL343HQ。

Abstract: [Objective] To screen the high quality and high yield alfalfa(Medicago sativa)cultivars suitable for local production conditions in Jiuquan area of Gansu Province. [Method] In Shangba Town, Suzhou District, Jiuquan City, Gansu Province, a total of 57 alfalfa materials from various ecological zones were sown. In the early squaring stage, diversity analysis and comprehensive evaluation of agronomic traits and yields were performed, followed by correlation analysis and principal component analysis among agronomic traits, cluster analysis, and comprehensive evaluation of membership function. [Result] The 57 alfalfa cultivars were divided into four categories. The cultivars with the lowest yield and comprehensive ranking were in the first category, and the ones with the highest were in the second category. The third category included materials with a high yield but poor in other indexes. The fourth category included the cultivars with moderate performance in yield and comprehensive ranking. [Conclusion] In this area, the alfalfa cultivars with better comprehensive assessment outcomes in the planting year are Zhongmu NO.3, North SLT, SR4030, and WL343HQ.
