Abstract：To better screen high-yield，high-quality，and adaptable alfalfa（Medicago satiua L.） varieties and improve alfalfa yield and new cultivar breeding efficiency，the individual plants of 11⋅WL ’seriesalfalfa varieties planted in the Hohhot region of Inner Mongolia were utilized in the experiment.The main phenotypic and quality indicators wereanalyzed and evaluated by using methods including coefficient of variation analysis，correlation analysis，and cluster analysis.The results showed that the coeficient of variation for the phenotypic and quality traits of the alfalfa varieties ranged from 2.86% to 22.62% . The trait with the largest coefficient of variation was dry weight，while neutral detergent fiber（NDF） was the smallest. Correlation and principal com ponent analysis revealed that plant height and stem diameter were important factors affecting forage yield，and the leaf-to-stem ratio is a major factor influencing alfalfa quality. Cluster analysis classified the 11⋅WL ’series alfalfa varieties into three groups.Among them，the Group II materials can be directly applied in production or used as parental material for the genetic improvement of high-yielding，high-qualityvarieties.The varieties in Group III can be further explored and utilized complementarily as breeding material for high-quality alfalfa.
