| 摘 要： | 以89份玉米自交系为试验材料,萌发期采用Na HCO3∶Na2CO3物质的量比为5∶1、浓度170 mmol/L盐碱胁迫处理,以发芽势、发芽率等8个性状为鉴定指标,对测量性状的隶属函数值进行主成分分析及聚类分析,从而对供试材料进行综合评价。结果表明,盐碱胁迫下品种表现差异显著,将89份玉米自交系划分为4类,其中高耐盐碱自交系7份,中耐盐碱自交系13份,盐碱一般敏感自交系27份,盐碱敏感自交系42份,19份耐盐碱材料可用于苗期或田间耐盐碱性研究。

| Abstract: | Eighty-nine maize inbred lines were used as experimental materials. During the germination period, MNaHCO3:MNa2CO3=5:1, 170 mmol/L saline-alkali stress treatment was used, and eight traits such as germination potential and germination rate were used as identification indicators. The functional evaluation, correlation analysis, principal component analysis and cluster analysis method were used to evaluate the results comprehensively. The results showed that the varieties showed significant differences under salt-alkali stress, and eighty-nine maize inbred lines were divided into four categories. Six parts of high saline-alkaline-resistant inbred lines, thirteen parts of moderate saline-alkaline-resistant inbred lines, twenty-seven parts of general salt-alkali-sensitive inbred lines, fortytwo parts of saline-alkali-sensitive inbred lines, nineteen parts of salt-alkali-resistant materials can be used for seedling stage or field resistance salt alkaline research. |
