Field experiments were conducted to select the Chinese oat varieties for forage production in the temperate environment of Bhutan. The seven oat varieties evaluated were Longyan No. 1, Longyan No. 2, Longyan No. 3, Qingyin No. 1, Linna, Stampede, and Fodder Oat of Bhutan (FOB). The parameters measured were morphological traits, dry matter production, and forage quality. The oat variety Qingyin No. 1 had the tallest plants (61 cm) and the largest number of tillers per plant (5 tillers per plant). The leaf-stem ratio (LSR) was highest for Longyan No. 2 (LSR 0.73). During harvest in late winter, Longyan No. 2 had the tallest plants (64 cm) and the highest number of tillers per plant (7 tillers per plant), followed by Qingyin No. 1. The top three varieties with high LSRs of 1.49, 1.31, and 1.35 were Longyan No. 1, 2, and 3, respectively. In both summer and winter, Longyan No. 2 had the highest forage yields, around 5.00 DM t ha -1 and 4.00 DM t ha -1 , respectively. Qingyin No. 1 was the second largest forage producer, with under 5.00 DM t ha -1 in summer and under 3.00 DM t ha -1 in winter. For forage quality, Longyan No. 2 and Longyan No. 3 each had the highest levels of crude protein, approximately 15% in summer, respectively. However, during late winter, the oat variety Linna had the highest crude protein content of about 13%. The overall results of the field experiments suggest that Longyan No. 2 and Qingyin No. 1 are promising new oat varieties for the production of winter fodder in temperate environments in Bhutan.
