抗旱丰产春小麦新品种陇春45号选育报告
Breeding Report on the New Drought-resistant and High-yield Spring Wheat Variety Longchun 45
摘要
Abstract
Drought-resistant,disease-resistant,and high-yielding varieties are the key to sustainable development of spring wheat production in central Gansu arid and semi-arid area and similar ecological areas.A new dryland spring wheat variety,Longchun 45,was successfully bred.This was achieved through sexual hybrid-breeding,using Ganchun 20 as the female parent and Longchun 27 as the male parent,with the application of pedigree method.In the 2020 to 2021 regional experiment of dryland spring wheat in Gansu Province,the average yield of Longchun 45 reached 3 220.28 kg/ha,which was 5.41%higher than that of the control variety,Xihan 2.In the 2022 production experiment of dryland spring wheat in Gansu Province,its average yield was 2 634.60 kg/ha,showing an 11.50%increase compared to Xihan 2.The growth period of this variety is 101 days.It has a plant height of 91.1 cm,with an average of 35.6 grains per spike and a thousand-grain weight of 43.3 g.It has a grain bulk density of 802 g/L,contains 160.4 g/kg crude protein(on a dry basis),385.0 g/kg wet gluten,and has a dough water absorption of 623 mL/kg,a dough formation time of 3.3 minutes,and a stabilization time of 2.1 minutes.Moreover,it has moderate resistance to stripe rust and powdery mildew,along with good drought resistance and lodging resistance.It is well-suited for cultivation in the dryland spring wheat areas of Gansu Province and regions with similar ecological conditions.关键词
