The study was conducted to evaluate the adaptability of a rye variety‘Gannong No. 3’in Northwest Sichuan region，with the conventional variety‘winter grazing 70’as a control. The plant height，fresh grass yield， hay yield and nutritional value were compared between the two rye cultivars at three sites，Hongyuan，Daofu and Bu- tuo of Sichuan province in 2018 and 2019. Results showed that the nutritional value as well the fresh grass yield and hay yield of‘Gannong No. 3’were significantly higher than those of‘winter grazing 70’(P＜0. 05). However， there was no significant difference in plant height and fresh dry ratio between‘Gannong No. 3’and the control. By contrast，the NDF content of‘Gannong No. 3’was significantly lower than that of‘winter grazing 70’. The content of ADF is significantly higher than‘winter grazing 70’. The crude protein content of‘Gannong No. 3’was slightly higher than that of the control but there was no significant difference between the two varieties. The production per- formance indicators of two rye varieties in Hongyuan and Daofu were significantly higher than that in Butuo point in both years. Comprehensive analysis showed that the production performance and nutritional value of rye variety‘Gan- nong No. 3’were better than those of the‘winter grazing 70’，and‘Gannong No. 3’is suitable for cropping in North- west Sichuan.
