小麦品种种子萌发期的抗旱性分析

o identify drought resistance of different wheat varieties, thirty wheat varieties during germination period were study by 10%PEG-6000 permeable medium as drought treatments, and all characters such as wheat storage matter transportation rate, root number, root length, coleoptile length, germination potential, germination index, germination rate and other physiological indexes were analysed by principal component. The results show that above seven individual indicators can combin into two new comprehensive indexes, then using cluster analysis method and membership function method to comprehensively evaluate the drought resistance on the germination period of Wheat Varieties , the results show that Jinmai 47, Shannong 757 have a weaker capacity, and Chang 6359, Henong 826, Luomai 21 etc. have a weak ability, While Han 6172, Cangmai 6005, Chang Hanmai 6154 etc. have Medium capacity, and Heng 136, Yunhan 20401, Yunhan618 etc. have stronger capability, while Yunong 4023, Henong 6331，Gaoyou 2018, Shijiazhuang 8, Zhongmai 175 have strongest capability.
