The comparative trial of the six introduced oat varieties was conducted in Jiangxigou Town of Gonghe County and their phenological period, morphological characteristics and grass yield were determined and compared. The results showed that Qingyin No.2, Qingyin No.l and Qinghai Sweet Oat exhibited better productive performance, indicating that these three varieties should be promoted in establishment of artificial forage base in Gonghe County.
