基　　金：2023年度喀什地区科技计划项目一喀什地区高值多抗首种质资源收集保存、品种筛选与示范推广应用研究(KS2023009)。

摘　　要：本研究利用国内外以及疆内的9个首品种为材料,对其株高、分枝数、根长、根颈粗、台数、单株地上部干鲜重、单株根部干鲜重等进行评价分析。结果可知,不同首品种之间的主要农艺性状及生物量存在不同程度差异性,其中WL363HQ的综合表现最好;单株地上部鲜重与分枝数呈显著正相关,单株地上生物量与根颈粗成显著正相关。农艺性状与生物量表现聚类分析结果显示,9个首品种被划分为3大类,WL363HQ、甘农5号、苜蓿得利为第Ⅰ类,在农艺性和生物量特征方面优于其他品种。此研究结果为喀什地区首新品种引进及推广提供初步理论依据,也为南疆干旱、盐碱地首种质资源评价利用、筛选适宜种植该地区的苜蓿新品种及相关育种研究工作提供有效的数据支撑。In this study,9 alfalfa varieties at home and abroad and in Xinjiang were used as materials to evaluate and analyze their plant height,branch number,root length,root neck diameter,number of units,dry and fresh weight of aboveground parts and dry and fresh weight of roots per plant.The results showed that the main agronomic traits and biomass of different alfalfa varieties were different,and the comprehensive performance of WL363HQ was the best.The aboveground fresh weight of single plant was significantly positively correlated with the number of branches,and the aboveground biomass of single plant was significantly positively correlated with the diameter of root neck.The results of cluster analysis of agronomic traits and biomass performance showed that 9 alfalfa varieties were divided into three categories,WL363HQ,Gannong No.5 and Mudeli were the first category,which were superior to other varieties in agronomic and biomass characteristics.The results of this study provide a preliminary theoretical basis for the introduction and promotion of new alfalfa varieties in Kashgar,and also provide effective data support for the evaluation and utilization of alfalfa germplasm resources in arid and saline-alkali land in southern Xinjiang,the selection of new alfalfa varieties suitable for planting in this area and related breeding research work.
