摘　　要：大豆产量由群体结构和个体生产力共同决定。其中,群体结构由个体的结荚习性、株高、主茎节数、分枝数、叶柄和叶片等株型性状决定;个体生产力由单株有效荚数、每荚粒数和粒重等性状决定,这些性状都具有特定的遗传和变异规律。表型设计育种是根据农作物表型性状的遗传和变异规律,设计出理想的表型性状值并培育出理想品种的育种技术。大豆品种齐黄34就是根据生态环境、生产条件和市场需求,采用表型设计育种技术选育成的高产大豆品种,具有株型紧凑、个体生产潜力大等特点。The yield of soybean is determined by the population structure and individual productivity.Population structure is determined by the plant type traits including stem termination,plant height,the number of nodes on main stem,branches,petioles,and leaves.Individual productivity is determined by the pods number per plant,seeds number per pod,and seed weight.Each trait has specific genetic and variation pattern.Phenotypic design breeding technology can design the ideal phenotypic value of the target traits and breed ideal crop varieties according to the genetic characteristics and variation range of these traits.Qihuang 34 is a high-yield soybean variety bred by the technology based on ecological environment,production conditions and market demand.It has the characteristics of compact plant type and large individual production potential.
