对引进的9个白菜型冬油菜品种(系)进行适应性试验，结果表明，参试品种(系)的越冬率、农艺性状、产量均优于对照品种陇油8号。初步筛选出丰产性、生育期以及综合性状良好，适合庆阳市栽培的冬油菜优良品种(系)2个，其中09鉴8折合产量为2 566.7 kg/hm2，比对照增产52.17%；QXI-24折合产量为2 460.0 kg/hm2，比对照增产45.85%。

Through the comparison with 9 Brassica campestris cultivars (lines) planted in the soil covered film two years ago, some Brassica campestris cultivars suitable for cultivation has been screened in Qingyang city. The result shows that yield of the line 09-Jian-8 is 2 566.7 kg/hm2， which is 52.17% higher than that of the check， the yield of the variety QXI-24 is 2 460.0 kg/hm2， which is 45.85% higher than that of the check.
