摘　　要：为了加强高粱耐盐碱种质资源研究利用,加快耐盐碱高粱新品种的选育步伐,本研究以17个耐盐碱高粱品系为材料,对其株高、茎粗、生育期、叶倾角等主要农艺性状进行相关性分析、主成分分析及ISSR分子标记聚类分析。结果表明,株高与茎粗、生育期与茎粗等呈极显著相关;主成分分析结果表明,前5个特征值在12个特征值中累积贡献率达85.3742%;当遗传系数为0.75时,可将17个不同品系耐盐碱高粱分为两大类群。研究表明,AT53、SW72、HH64、S8、WS912和TT656综合性状优异。In order to strengthen the research and utilization of saline-alkali tolerant germplasm resources of sorghum,and accelerate the pace of breeding of new saline-alkali tolerant sorghum varieties.The main agronomic traits including plant height,stem diameter,growth period,leaf angle of inclination of 17 salt-alkali tolerant sorghum strains were analyzed by correlation analysis,principal component analysis and ISSR molecular marker cluster analysis.The results showed that the correlation between plant height and stem diameter,growth period and leaf angle of inclination were significantly correlated.Principal component analysis showed that the cumulative contribution rate of the first 5 characteristic roots reached 85.3742%among the 12 characteristic values.When the genetic coefficient was 0.75,17 different strains of salt-alkali tolerant sorghum could be divided into two groups.Study indicated that AT53,SW72,HH64,S8,WS912 and TT656 showed excellent comprehensive traits.
