Breeding Report on the New Functional Purple Grain Spring Wheat Variety Longchun 46
摘要
Abstract
Functional wheat varieties can regulate beneficial metabolism and fill the needs of specific population.A new purple grain wheat variety Longchun 46 was bred to fill the vacancy of wheat varieties for special purposes such as nutrition and functionality in Hexi irrigation region.Through artificial selection in different ecological places,this variety was selected from the cross of 4E-ms genic sterile light blue grain maintainer line 3046B-1 as female parent and Longchun 432 as male parent.In 2022,it participated in the spring wheat regional experiment in the west area of Gansu Province,with an average yield of 7 424.10 kg/ha,an increase of 4.17%over the control variety Ningchun 4.In 2023,it participated in the spring wheat production experiment in the west area of Gansu Province,with an average yield of 7 660.96 kg/ha,an increase of 1.97%over the control variety Ningchun 4.Longchun 46 exhibits characteristics such as compact plant type,moderate height,long awn,white husk,and horny grains.The number of granis per spike is 42 and 1000-grain weight is 43.9 g.It showes moderately susceptible to powdery mildew and rust,and its quality reached medium-strong gluten.The grain contains crude protein of 146.7 g/kg,wet gluten of 325.0 g/kg,bulk density of 810 g/L,dough water absorption of 615 mL/kg,dough stability time 1.0 min,and weakening degree of 209 F.U,and is rich in various vitamins,trace elements,and amino acids.It is suitable for planting in Hexi area of Gansu Province and similar ecological areas.关键词
