Abstract：In order to compare the lodging resistance of different oat （ A vena satiua L.） germplasms and explore the main factors afecting their lodging resistance，in this study we took 9oat varieties as experimental materials to explore the relationship between ear characteristics，stem morphological characteristics and the content of stem chemical substances and lodging resistance. Further，grey corelation analysis was performed to identify the key traits affecting lodging resistance in oat. Meanwhile，membership function method and cluster analysis were used to comprehensively evaluate and cluster the oatmaterials tested in this study.The excellnt varieties and characters were screenedout preliminarilyto provideparental materials and reference for breeding in the future.The results show that：AO5，AN222，and AOl had the strongest lodging resistance. The key factors ffecting the resistance to lodging in oats are center of gravity height，second internode length，stem diameter coefficient，spike length，internode length below the spike，potassium，and cellulose.
