抗旱高产小麦品种洛旱22是洛阳市农林科学院2005年以周麦16为母本、自育抗旱材料洛9769(洛旱7号)为父本，采用洛阳市农林科学院所创抗旱高产小麦高效育种技术选育而成，于2018年通过审定(审定编号：国审麦20180058)。自审定以来，对洛旱22特征及应用进行了诸多研究，其抗旱指数为0.900～1.130，抗旱性2～3级，综合抗旱性较好；株高75 cm左右，基部节间短，抗倒伏；弱冬性，抗寒性好；根系发达，下扎深，总根长比对照洛旱7号高28.39%；区域及生产试验3年平均产量6 560.0 kg/hm2，平均增产点率97.8%；经连续多年多点大面积生产示范，在生育期降水量低于300 mm的欠水年份可实现平均产量6 716.6 kg/hm2，而在生育期降水量高于500 mm的丰水年份高产潜力达9 892.8 kg/hm2，充分体现了洛旱22旱年高产、稳产特性。该品种实现了抗旱性和丰产性的协同提升，解决了黄淮旱肥地及扩灌麦区抗旱与高产难以协调的矛盾，为保证区域粮食安全提供了品种支持和栽培技术保障。
Abstract：The new wheat variety Luohan 22, characterized by drought resistance and high yield, was developed by the Luoyang Academy of Agriculture and Forestry Sciences in 2005. Utilizing our innovative high-efficiency breeding technology tailored for drought-resistant and high-yield wheat, it was bred with Zhoumai 16 as the maternal parent and the self-developed drought-resistant line Luo 9769(Luohan No.7) as the paternal parent. The variety was approved by the state in 2018(Approval Number: Guoshenmai20180058). Since its approval, extensive research has been carried out on the characteristics and applications of Luohan 22. Its drought-resistant index ranges from 0.900 to 1.130, with a drought resistance rating of 2 to 3, indicating good overall drought tolerance.T he plant height is approximately 75 cm, featuring short basal internodes that confer resistance to lodging. It exhibits weak winter hardiness but possesses excellent cold resistance. The root system is robust and deeply rooted, with a total root length 28.39% greater than that of the control variety Luohan No.7. Over three years of regional and production trials, the average yield reached 6 560.0 kg/hm2, with an average yield increase rate of 97.8%. After multiple years of large-scale production demonstrations across various locations, the average yield achieved 6 716.6 kg/hm2 in drought years with precipitation below 300 mm during the growth period, while demonstrating a high-yield potential exceeding 9 892.8 kg/hm2 in years with precipitation above 500 mm. This underscores the high and stable yield performance of Luohan 22 under drought conditions. This variety achieves a synergistic enhancement of both drought resistance and high yield, resolving the long-standing challenge of reconciling drought resistance with high productivity in the Huang-Huai dry and fertile lands and expanded irrigation areas, which can provide crucial variety support and cultivation technology guarantees for ensuring food security.
