Six parameters—germination potential (GP), germination rate (GR), germination index (GI), vigor index (VI), root length (RL), and shoot length (SL) were measured. A comprehensive evaluation was conducted using coefficient of variation analysis, correlation analysis, principal component analysis (PCA), subordinate function analysis (SFA), and cluster analysis. The results revealed significant variation in salt tolerance during germination among the 59 alfalfa accessions. Based on PCA and correlation analysis, four key indicators were selected for salt tolerance evaluation: relative germination potential (RGP), relative germination rate (RGR), relative germination index (RGI), and relative shoot length (RSL). Cluster analysis based on D-values derived from SFA classified the 59 germplasms into five salt tolerance categories: highly salt-tolerant (1 accession), moderately salt-tolerant (22 accessions), low salt-tolerant (11 accessions), salt-sensitive (11 accessions), and highly salt-sensitive (14 accessions). Seven accessions exhibiting strong salt tolerance were identified: ‘Juneng 6’‘Ningmu No.1’‘Salt treasure’‘Shockwave’‘Aohan’‘Hunter River’ and ‘Challenger’. These findings provided a theoretical basis for alfalfa salt tolerance breeding., authors=YANG Jin-hui1 , WANG Xiao-tong1 , MA Yong-long1 , YU Dong-wen1 , TONG Yu-hua1 , MA Meng-fan1 , LI Shu-xia1 ,

articleAbstract=为筛选出适宜在盐碱土壤上栽培的紫花苜蓿(Medicago sativa L.)材料,本研究对59份紫花苜蓿种质的萌发期耐盐性进行了评价。通过测定发芽势、发芽率、发芽指数、活力指数、根长和苗长6项指标,并综合运用变异系数法、相关法、主成分法、隶属函数法及聚类法,评价其萌发期耐盐性。研究结果表明:59份紫花苜蓿种质的萌发期耐盐性存在显著差异,相对发芽势、相对发芽率、相对发芽指数和相对苗长适合用作紫花苜蓿萌发期耐盐性评价指标。基于隶属函数值进行聚类分析,可将59份紫花苜蓿种质资源划分成超强耐盐型(1份)、中强耐盐型(22份)、低强耐盐型(11份)、弱耐盐型(11份)和超弱耐盐型(14份)5个类别,筛选出强耐盐性种质材料为‘巨能6’‘宁苜1号’‘盐宝’‘冲击波’‘敖汉’‘猎人河’和‘挑战者’。研究结果为紫花苜蓿耐盐育种提供理论支撑。,

为筛选出适宜在盐碱土壤上栽培的紫花苜蓿(Medicago sativa L.)材料,本研究对59份紫花苜蓿种质的萌发期耐盐性进行了评价。通过测定发芽势、发芽率、发芽指数、活力指数、根长和苗长6项指标,并综合运用变异系数法、相关法、主成分法、隶属函数法及聚类法,评价其萌发期耐盐性。研究结果表明:59份紫花苜蓿种质的萌发期耐盐性存在显著差异,相对发芽势、相对发芽率、相对发芽指数和相对苗长适合用作紫花苜蓿萌发期耐盐性评价指标。基于隶属函数值进行聚类分析,可将59份紫花苜蓿种质资源划分成超强耐盐型(1份)、中强耐盐型(22份)、低强耐盐型(11份)、弱耐盐型(11份)和超弱耐盐型(14份)5个类别,筛选出强耐盐性种质材料为‘巨能6’‘宁苜1号’‘盐宝’‘冲击波’‘敖汉’‘猎人河’和‘挑战者’。研究结果为紫花苜蓿耐盐育种提供理论支撑。

To screen alfalfa (Medicago sativa L.) germplasm suitable for cultivation on saline soils, this study evaluated the salt tolerance of 59 alfalfa germplasm accessions during the germination stage. Six parameters—germination potential (GP), germination rate (GR), germination index (GI), vigor index (VI), root length (RL), and shoot length (SL) were measured. A comprehensive evaluation was conducted using coefficient of variation analysis, correlation analysis, principal component analysis (PCA), subordinate function analysis (SFA), and cluster analysis. The results revealed significant variation in salt tolerance during germination among the 59 alfalfa accessions. Based on PCA and correlation analysis, four key indicators were selected for salt tolerance evaluation: relative germination potential (RGP), relative germination rate (RGR), relative germination index (RGI), and relative shoot length (RSL). Cluster analysis based on D-values derived from SFA classified the 59 germplasms into five salt tolerance categories: highly salt-tolerant (1 accession), moderately salt-tolerant (22 accessions), low salt-tolerant (11 accessions), salt-sensitive (11 accessions), and highly salt-sensitive (14 accessions). Seven accessions exhibiting strong salt tolerance were identified: ‘Juneng 6’‘Ningmu No.1’‘Salt treasure’‘Shockwave’‘Aohan’‘Hunter River’ and ‘Challenger’. These findings provided a theoretical basis for alfalfa salt tolerance breeding.
