冬小麦新品种陇麦671的选育及思考
Breeding and Considerations of New Winter Wheat Variety Longmai 671
摘要
Abstract
To address the issues of drought,cold,and disease in wheat production in China's arid and semi-arid regions,a compatible wheat variety named Longmai 671 was bred.This variety combines drought resistance,water conservation,cold resistance,disease resistance,high yield,and superior quality.It was developed by crossing Pingliang 43 as the female parent with Zhong 41-42 as the male parent,using alternating water and drought stress and multi-location shuttle breeding.In the 2018 to 2020 regional experiment in the eastern Gansu winter wheat zone,Longmai 671 had an average yield of 4 981.5 kg/ha,which was 12.2%higher than the control variety Longyu 4.In the 2020 to 2021 production experiment,it had an average yield of 6 889.5 kg/ha,22.4%higher than Longyu 4.Longmai 671 is characterized by high yield,superior quality,drought resistance,water conservation,disease resistance,cold tolerance,dwarf stalk,and lodging resistance.The variety has a plant height of 85.2 cm,33.4 grains per spike,a thousand-grain weight of 33.0 g,a bulk density of 789 to 802 g/L,and a drought index of 0.975.The grain contains 162.0 g/kg of crude protein(dry basis),3.6 g/kg of lysine(dry basis),374.0 g/kg of wet gluten(14%moisture basis),and a sedimentation value of 44.0 mL(14%moisture basis).It is suitable for planting in the dryland and river terrace areas of eastern Gansu and similar regions.关键词
