摘要: 小麦是山西省主要栽培作物,旱地小麦产量左右着山西省小麦总产的高低,选育抗旱高产稳产小麦新品种是增加旱地小麦面积和提高小麦产量的重要途径。经过系谱杂交育种法,选育出抗旱高产小麦新品种‘长麦6197’。在2015、2016 年山西省中部晚熟冬麦区旱地组区域试验中,2 年平均折合产量5466 kg/hm2,较对照品种‘长6878’增产6.5%,2017 年同区组生产试验中‘长麦6197’平均折合产量5547 kg/hm2,较对照品种‘长6878’增产9.2%。该品种株型紧凑,茎秆弹性好,抗旱、抗倒、抗冻、抗青干、高产稳产、灌浆落黄好。‘长麦6197’于2017 年12 月通过山西省农作物品种审定委员会审定,适宜在山西省中部晚熟冬麦区旱地种植。

Abstract: Wheat is the main cultivated crop in Shanxi, and its yield in dryland decides total wheat yield of the province. So, breeding wheat varieties with drought-resistance and high, stable yield is an important way to increase wheat planting area and yield in dryland. After phylogenetic crossbreeding, a new high yield wheat variety‘Changmai 6197’was selected; in the regional trials of the late-mature winter wheat region in central Shanxi in 2015 and 2016, 2-year average yield of the variety was 5466 kg/hm2, which was 6.5% higher than that of the control variety‘Chang 6878’; in the 2017 yield test in the same region, the average equivalent yield of‘Changmai 6197’was 5547 kg/hm2, which increased by 9.2% compared with that of‘Chang 6878’. ‘Changmai 6197’has compact plant type, good stalk elasticity, drought resistance, lodging resistance, frost resistance, resistance to dry stem, high yield and stable yield, and good grouting and yellowing, and was approved by the Shanxi Crop Variety Approval Committee in December 2017. It is suitable for planting in dryland in late-mature winter wheat areas in central Shanxi.
