Breeding Report on the New Spring Wheat Variety Longchun 48 with Early Maturity and High Quality
摘要
Abstract
In order to realize the cooperative improvement of multi-objective traits such as early maturity,high quality,high yield and grain traits of spring wheat varieties,and to address the needs of spring wheat varieties in the irritated area of Gansu Province,since 2012,the Wheat Research Institute of Gansu Academy of Agricultural Sciences has successfully bred a new medium gluten spring wheat variety Longchun 48 with early maturity,high quality and high yield through artificial hybridization.Its parent combination is winter dwarf male sterile plant/Yong T28.The average equivalent yield of this variety in the 2022 to 2023 western irritated spring wheat regional experiment in Gansu Province was 7 961.75 kg/ha,an increase of 8.32%compared to the control variety Ningchun 4.In the 2024 spring wheat production experiment in the western part of Gansu Province,the average equivalent yield was 7 930.80 kg/ha,which was 7.01%higher than the control variety Ningchun 4.Longchun 48 has a plant height of 78 cm,a compact plant shape,nearly spindle shaped spikes,long awns,white shells,white grains,keratinized grains,and excellent plumpness.The number of effective panicles is 6.405 million ears/ha,the number of grains per spike is 44.0,and the thousand grain weight is 43.4 g.The grain contains 132.6 g/kg of crude protein(dry basis),289.0 g/kg of wet gluten,and 834 g/L of buck density.The flour characteristics include a dough water absorption of 627 mL/kg,a dough formation time of 4.5 min,a stabilization time of 5.0 min,a stretching area of 47 cm2,an extensibility of 162 mm,and a maximum stretching resistance of 202 E.U,meeting the national standard for medium gluten wheat varieties.The field production shows strong lodging resistance,immunity to powdery mildew and moderate susceptibility to stripe rust,which is suitable for popularization and planting in irrigated spring wheat type areas and similar ecological areas in Gansu Province.关键词
