摘　　要：为甘肃省小麦生产提供抗旱、抗病、丰产、优质小麦新品种,以促进小麦更新换代,实现小麦稳产增产,以衡7728为母本、陇春27号为父本进行了有性杂交,通过异地生态选择、采用系谱法成功选育出了抗旱丰产春小麦新品种陇春43号。2018—2019年参加甘肃省旱地春小麦区域试验,平均折合产量3074.70 kg/hm^(2),较对照品种西旱2号增产10.02%。2020年参加甘肃省旱地春小麦生产试验,平均折合产量3582.61 kg/hm^(2),较对照品种西旱2号增产9.81%。该品种具有高产稳产,优质,株型紧凑,抗旱,抗倒伏,中抗条锈和白粉病等特点,适宜在甘肃省中部旱地春麦区以及类似生态地区种植。Longchun 43,a new drought-resistant and high-yield spring wheat variety,was bred through sexual hybridized combinations with Heng 7728 as the female parent and Longchun 27 as the male parent.This breeding program aimed to provide Gansu Province with new wheat varieties that possess drought resistance,disease resistance,high yield,and high quality,thereby promoting wheat variety update and achieving a stable increase in wheat yield.Through ecologic selection in different locations and pedigree analysis,Longchun 43 was successfully bred.Regional experiments conducted in Gansu Province from 2018 to 2019 showed that the average yield over two years was 3074.70 kg/ha,which was 10.02%higher than that of the control variety Xihan 2.Furthermore,production experiments in 2020 demonstrated that the average yield was 3582.61 kg/ha,representing a 9.81%increase compared to the control variety Xihan 2.Longchun 43 exhibits characteristics such as high and stable yields,high quality,compacted plant shape,drought resistance,lodging resistance,medium resistance to stripe rust and powdery mildew.It is suitable for cultivation in the dryland spring wheat variety area in central Gansu Province,as well as in similar ecological environments.
