Abstract：To determine the production performance and suitable planting area of triticale （x Triticosecale Wittmack）variety‘Zangsi No.3’in Xizang pastoral area，the plant height，tiller number，fresh yield and hay yield of‘Zangsi No.3’ in Namling，Dagzé and Lazi experimental sites were studied in 2O22 and 2O23，with triticale varieties‘Zangsi No.1’ and‘Gannong No.2’as controls. The results showed that the average hay yield of three triticale varieties in 2O23 was significantly higher than that in 2022（ P<0.05） ，but there were no significant difference in average plant height，tiler number and fresh yield.From the experimental sites of view，the average plant height，fresh yield and hay yield of the three triticale varieties in Namling experimental site were significantly higher than those in Dagzé and Lazi experimental sites （ ⋅P<0.05） ，and the average tiller number in Lazi experimental site was the highest （ .P<0.05） .From the difference of years x experimental sites .× varieties，the fresh yield （52.80t⋅hm-2 ） of‘Zangsi No. in Namling experimental site in 2O22 was significantly higher than other varieties （ ，and the hay yield of this variety was the highest in 2023， 19.08t⋅hm-2 significantly higher than the control varieties （ P<0.05） .From the comprehensive evaluation，the comprehensive evaluation value of‘Zangsi No.3’ in Namling experimental site was the highest in 2O22 and 2O23，and its production performance was the best. In summary，the production performance of‘Zangsi No.3’ was beter than‘Zangsi No.1’ and‘Gannong No.2’，which was suitable for planting in Namling experimental site and other similar climate area.
