Abstract: For selecting aging resistant varieties in peanut and measuring main quality characters before and after the aging, we used 18 peanut varieties from different resources for the estimation of aging resistant ability through artificial aging and germination rate detection. We found the oblivious decline of germination rate after aging for 8 days, and based on which, we identified 5 varieties with strong aging resistant abilities (germination rate>90% after aging for 8 days); through character measurement and association analysis, we found acid value as the most alterable factor before and after aging, and the relationship between the aging resistant ability and oleic/linoleic acids contents. The reliable varieties we identified might be helpful for the genetic improvement of peanut and the related researches.
