Breeding Report on the New Drought-resistant and High-yield Spring Wheat Variety Huining 22
To promote the renewal of new dryland spring wheat varieties and achieve drought resistance,disease resistance,high yield,and stable yield in wheat production,Huining 22,a new dryland spring wheat variety,was bred by crossing Dingxi 35 as the female parent with Ganchun 25 as the male parent using the pedigree method.This variety has a growth period of 107 days,a plant height of 115 cm,31 grains per spike,and a thousand-grain weight of 48.8 g.In the 2019 to 2020 Gansu Province dryland spring wheat regional experiment,the average yield was 3 772.80 kg/ha,an increase of 7.58%compared to the control variety Xihan 2.In the 2021 Gansu Province dryland spring wheat production experiment,the average yield was 2 733.00 kg/ha,an increase of 7.29%compared to the control variety Xihan 2.This variety is medium-maturing,with grain protein content(dry basis)of 131.3 g/kg,wet gluten(14%moisture basis)of 301.0 g/kg,falling number of 339 s,Zeleny sedimentation value of 20.8 mL,water absorption rate of 63.6%,and bulk density of 804 g/L.It has moderate resistance to stripe rust and high resistance to powdery mildew which is suitable for planting in the spring wheat areas of central Gansu's dry and semi-arid regions and similar ecological zones,especially suitable for dry plateau areas.
