为能更好地培育出适合会宁旱地农业区种植的抗逆性强、丰产性好的春小麦新品种，加快当地春小麦新品种利用和更新换代，在会宁半干旱春麦种植区对近年来选育出的9个旱地春小麦新品系进行了品比试验。结果表明，轮选07068-3-16生育期为100 d，较对照品种西旱2号早熟4 d；出苗率高，抗倒性强；丰产性优，较对照品种西旱2号增产9.06%，且产量差异达极显著水平。06083-7-6、06024-10-9抗逆性较强，成熟落黄好，籽粒饱满，色泽好，产量较高，均较对照品种西旱2号增产7.25%。综合考虑，轮选07068-3-16、06083-7-6，06024-10-9综合农艺性状表现优良，建议进入甘肃省旱地春小麦区域试验。

To breed better spring wheat variety suitable for the dryland area of Huining with good resistance and high yield and to speed up the upgrading of local wheat variety utilization, 9 spring wheat new lines were used to conduct comparison experiment in semi-arid spring wheat production area of Huining. Results showed that that the growth period of 07068-3-16 was 100 days, which was 4 days shorter than that of Xihan 2. The seedling emergence rate, lodging resistance and yield of 07068-3-16 were higher than those of Xihan 2. The yield of 07068-3-16 was 9.06% higher than that of Xihan 2 and the difference was extremely significant. 06083-7-6, 06024-10-9 had strong stress resistance, good maturity and yellowing, full grain, and good color, the yield was increased by 7.25% compared with the control Xihan 2. Comprehensively speaking, 07068-3-16, 06083-7-6 and 06024-10-9 showed excellent comprehensive agronomic characters and was recommended to enter the regional trial for the spring wheat in dryland area.
