The 50 oat materials were taken as the research objects to find out the effects of oat agronomic traits and forage quality on its cutting and regeneration performance.The results showed that the variation of flag leaf area and dry matter mass were large(CV＞15％)and the variation of chlorophyll content was small(CV=6.69％);The contents of crude fat,neutral detergent fiber,calcium and phosphorus in quality traits were significantly different(CV＞15％).Correlation analysis showed that,flag leaf area,chlorophyll content,contents of crude protein,crude fat,soluble sugar,calcium and phosphorus were significantly positively correlated with oat regeneration performance.Cluster analysis of yield and quality showed that Longyan 3,G138,Haywire,Yuanza 1,Mengyan 1,Bayou 18,Dingyan 2,G142,G144,Linna and Yanke 2 with high yield were recommended to be planted in areas with poor climate environment;In areas with abundant water and heat resources,it is recommended to plant the oats with high quality such as Qingyin 3,Qingyin 1,Yanke 2,Beile,Monida,Baiyan 8,Jiayan 7,Baiyan 19,Yanke 1,Neiyan 5 and Bayou 3.
