Breeding Report on the Winter Wheat Variety Yunong 523 with Drought Resistance and High Yield
摘要
Abstract
In order to breed new winter wheat variety with drought resistance,high yield and wide adaptability suitable for planting in dry farming areas and other similar areas in Henan Province,Henan Agricultural University carried out sexual hybridization with Luohan 2 as female parent and self-bred variety Yunong 416 as male parent.After years of continuous pedigree selection of hybrid offspring using alternate planting of water and drought,a new winter wheat variety Yunong 523 with high yield and drought resistance was bred.During 2019 to 2021,it participated in the wheat regional experiment of dry areas in Henan Province.The average yield in 2 years was 5 760.1 kg/ha,which was 3.8%higher than that of the control variety Luohan 7.Data from the production experiment from 2021 to 2022 showed that the average yield was 6 586.5 kg/ha,which was 6.2%higher than that of the control variety Luohan7.The plant height of this variety is 73.3 cm,the number of effective panicles is 5.14×106/ha,the number of grains per spike is 34.0 and the 1000-grain weight is 47.0 g.Its average grain bulk weight,crude protein(dry basis),wet gluten,dough stability time and water absorption capacity are 808 g/L,148 g/kg,324 g/kg,3.4 min and 585 mL/kg,respectively.It has the characteristics of high yield,drought resistance and lodging resistance,and is suitable for planting in hilly and arid fertile land areas in Henan Province.关键词
