Abstract：Using 5 oat (Avena sativa L.)varieties,Bayan 4,Bayou 3,Baiyan 2,Bayou 1 and Fengli,as experimental materials,their yield and quality indexes were comprehensively analyzed by grey system theory in the earing stage,filling stage and milk stage.The results showed that,with the delay of growth period,the dry matter content increased,and the differences were significant (P <0.05).Compared with the earing stage and filling stage,the dry matter content in the milk stage increased by 46.18% and 15.44% respectively.The crude protein,crude ash,calcium and phosphorus contents in the milk stage were lower,while the tendency of crude fat content was an exception.The Fengli got lower crude protein content,but the highest fresh and dry matter content,which increased by 12.81% ~34.61% and 23.25% ~43.04%,respectively,compared to other culti-vars.The Baiyan 2 got higher levels in crude protein,crude fat,crude ash and calcium content.Using the en-tropy weight -based gray systematic theory,the integrated evaluation was done on the yield and quality indexes. In conclusion,the optimal cultivar was Baiyan 2,followed by Bayou 1 and Bayan 4 performed the worst.Fur-thermore,the optimal yield and quality was achieved in the earing stage.
