Abstract:

【Objective】 To identify and evaluate the salt tolerance of 180 upland cotton germplasm resources at germination stage, screen excellent germplasm, and provide resource materials for the creation of new salt-tolerant germplasm. 【Methods】 In this study, 150 mmol/L NaClsolution was used to simulate salt stress, and 180 germplasm resources were identified and screened for salt tolerance during seed germination. And then, the salt tolerance of these resources was evaluated by principal component analysis and membership function method. 【Results】 Four comprehensive indexes were obtained by principal component analysis, and the comprehensive evaluation D value of salt tolerance was calculated according to the weight. The 180 germplasm resources were divided into five categories by cluster analysis. 【Conclusion】 There are significant differences in relative germination potential and relative germination rate among 180 germplasm resources under salt stress and ten salt-tolerant materials and 31 salt-sensitive materials are obtained by screening.

Key words: cotton; germination stage; salt tolerance; comprehensive evaluation

摘要:

【目的】鉴定评价180份陆地棉种质资源材料萌发期耐盐性,筛选优异种质,为耐盐新种质的创制提供资源材料。【方法】以150 mmol/L NaCl 溶液模拟盐胁迫,于种子萌发期对180份种质资源进行耐盐性鉴定及筛选,通过主成分分析、隶属函数法等评价180份种质资源耐盐性。【结果】得到4个综合指标,并依据权重计算出耐盐性综合评价D值,180份种质资源分成了五类。【结论】盐胁迫下180份种质资源在相对发芽势、相对发芽率等指标上存在显著差异,得到了10份耐盐性材料与31份盐敏感性材料。
