宁南山区旱地冬小麦品种筛选研究

[目的]筛选出特征特性良好、丰产性状突出、适合在宁南山区干旱半干旱生态条件下生产利用的旱地冬小麦品种(系)。[方法]对宁南山区选育的14个冬小麦品种进行适应性、丰产性、抗逆性鉴定。[结果]参试的14个品种产量普遍较高,平均产量为2 310.75~3 992.25 kg/hm~2,与对照品种中引6号相比,其他品种产量增幅为15.98%~72.78%,但各参试品种产量之间差异不显著(F值F_(0.05))。[结论]陇育0869-2、Z0231-3、西平1号、陇育0670-2、06AWS006、98-5808-2、Z0349-4和X0309-14-3这8个品种保留旱地品比试验。

Screening of Dryland Winter Wheat Varieties in South Mountainous Areas of Ningxia

Objective] To screened out good characteristics and high yield traits of dryland winter wheat varieties that was suitable for produc-tion under the ecological conditions of arid and semi-arid mountainous area of southern Ningxia.[Method] The adaptability, high yield and re-sistance of 14 winter wheat species were identified in south mountainous areas of Ningxia .[ Result] Yields of 14 tested varieties were generally higher, with the average yield being 2 310.75-3 992.25 kg/hm2 .Compared with the control Zhongyin 6, increase of the yield of other varie-ties was between 15.98% and 72.78%.However, there were no significant differences in the yield of different tested varieties (F value
