摘要: 中麦9号由多亲本复合杂交并经连续16年系谱法选择育成。其在大田生产中的实际亩产达到9 603 kg·ha-1,在国家黄淮北片区试中比对照平均增产6.7%;对条锈、叶锈、白粉等病害均为持久的中抗水平,抗吸浆虫,抗倒伏,不易穗发芽;光截获性能好,籽粒灌浆中期充实速率快,生育后期遇高温时表现气-冠温差大,有利于形成大粒。通过完善中麦9号的良种繁育体系,研制和推广了可发挥该品种大穗大粒特点的缩小行距栽培和“推迟春一水”肥水调控技术,使严重缺水的华北地区农户种植该品种可少浇水一次。示范推广10年来经受了种植结构调整的考验,播种面积连续稳定在每年15万公顷左右。中麦9号的育成和推广,打破了北部冬麦区以多穗型为主的产量结构模式,建立起新的大穗大粒育种技术路线,将本麦区小麦产量育种水平提高到一个新台阶。

Abstract: Zhongmai No.9 was bred by multiple cross and 16-year pedigree selection. It has a good light interception ability, high filling rate, low canopy temperature depression in later growth stage, durably moderate resistance to stripe rust, leaf rust and powdery mildew, and insusceptible to Sitodiplossis mosellana (Gehin), lodging and preharvest sprouting. It presents outstanding yield with an yield record of 9 603 kg·ha-1. Its average yield was 6.7% higher than that of the control variety in the National Wheat Variety Regional Tests. An effective seed-production and cultivation technique system was built for Zhongmai No.9 by reducing row spacing and deferring watering in spring. By planting Zhongmai No.9, farmers could save one-time waterirrigation in the North China. Its sown area was kept around 150 000 ha per year in the past 10 years. The development and extension of Zhongmai No.9, a new breeding strategy paying more attention to large grains and spikes was developed, which broke the yield structural model based on multi-spikes in northern winter wheat region and improved wheat yield potential.
