Abstract：A field experiment was conducted to evaluate the growth characteristics and seed yield of eight spring rapeseed varieties under two planting patterns—open -field cultivation and semi-film mulching—in Qingcheng County and Zhengning County，Gansu Province.The growth period， plant growth characteristics，and seed yield were analyzed.The results showed that all eight varieties maturedaround15July，with no significant effects of sowing time or planting patern on the maturity date.Among the varieties，‘Longyouza No.1’had the greatest average plant height （150.1 cm），numberof primary effective branches （7.5 per plant），and main inflorescence length （52.9 cm），significantly greater than those of the other varieties.‘Shanyou No. 168⋅ had the highest number of secondary effctive branches （6.9 per plant），while‘Fengyou No.3O6’produced the longest siliques （ ：7.2cm ）.‘Qinyou No. 558∘ had the greatest effective branch height （ 86.3cm ）.In terms of yield，‘Longyouza No. 1⋅Γ and‘Longyouza No. had the highest seed yields， reaching 114.4kg per 667 m² and 111.2kg per 667m2 ，respectively， indicating their suitability for cultivation in the Longdong region.
