为实现春小麦品种在早熟性、优质性、高产性及籽粒性状等多目标性状上的协同改良，满足甘肃省水地春小麦产区的品种需求，甘肃省农业科学院小麦研究所自2012年开始，通过人工杂交成功选育出了早熟、优质、高产的中筋春小麦新品种陇春48号，其亲本组合为冬性矮败可育株/永T28。该品种在2022 — 2023年甘肃省西片水地春小麦区域试验中，平均折合产量7 961.75 kg/hm2，较对照品种宁春4号增产8.32%；在2024年甘肃省西片水地春小麦生产试验中，平均折合产量7 930.80 kg/hm2，较对照品种宁春4号增产7.01%。陇春48号株高78 cm，株型紧凑，穗型为近纺锤形，长芒，白壳、白粒，籽粒角质，饱满度优良；有效穗数640.5万穗/hm2，穗粒数44.0粒，千粒重43.4 g。籽粒含粗蛋白(干基)132.6 g/kg、湿面筋289.0 g/kg，容重834 g/L。粉质特性为面团吸水量627 mL/kg，面团形成时间4.5 min、稳定时间5.0 min，拉伸面积47 cm2，延伸性162 mm，最大拉伸阻力202 E.U，达到国家中筋小麦品种标准。田间表现抗倒伏能力强，免疫白粉病，中感条锈病，适宜在甘肃省水地春小麦类型区及相似生态区推广种植。

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.
