摘　　要：[ Objective] To find orchardgrass cultivars which have high seed production and can be planted in western Chongqing region. [ Method] Seed production and phenophase were compared between several common orehardgrass cultivam （domestic or foreign） in western Chongqing region. A high-yield high-quality orchardgrass line suitable for seed production in western Chongqing region was found, [ Result] The orohardgra^s in western Chongqing region had excellent seed production performance. Among these cultivars, orGhardgrass 01076 had the highest seed produc. tion, up to 512 kg/hm^2. Its germinability, germination rate and germination index were also highest, 49%, 84% and 11, respectively. [Condusion] The orchardgrass 01076 is worth planting in large scale in westem Chongqing region for seed production.[ Objective] To find orchardgrass cultivars which have high seed production and can be planted in western Chongqing region.
