Abstract:The drought resistance of 26 peanut cultivars at seedling stage was studied under the simulated drought stress condition with PEG6000 in green house by hydroponics.The main stem height,aboveground bi-omass,root biomass and root cap ratio of peanut seedlings were determined,the statistical analyses on drought-resistant index and coefficient of drought-resistant related traits were conducted,then the osmotic stress re-sistance at seedling stage of different varieties were comprehensively analyzed through clustering analysis, drought resistance level evaluation assign points method and standard deviation coefficient weighting method. The results showed that the peanut varieties with higher resistance to osmotic stress at seedling stage were Yuanza 9102,Ji 0212-4,Xianghua 2008 and NC6;the varieties with weaker resistance were Baisha 1016, 04D029,Taishanzhenzhu,Laiwuhuapi,02P172 and ND1 19.
