抗旱丰产春小麦新品种陇春43号选育报告
Breeding Report of New Drought-resistant and High-yield Spring Wheat Variety Longchun 43
摘要
Abstract
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 3 074.70 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 3 582.61 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.关键词
