育种的目的是不断提供能生产更多人们所需要的新品种,而其本身的成功与否则很大程度取决于育种材料和方法的优劣。在今后的大豆育种研究中,为了兼顾这两者,总体的育种研究方向仍是以下三个层次:一是商用新品种的选育;二是目标性状的亲本创新和新品种(系)选育;三是种质改良与育种方法的基础研究。三个层次侧重不同,而后一层次内容均可视为其上一层次内容的基础,因而更应受到重视。为达 The goal of breeding is to continually provide new breeds that are needed to produce more people, and their own success or not depends very much on the pros and cons of breeding materials and methods. In the future researches on soybean breeding, in order to take both of them into consideration, the general direction of breeding research is still the following three levels: one is the breeding of commercial new varieties; the other is the innovation of parental traits and selection of new varieties (lines) ; Third is the basic research of germplasm improvement and breeding methods. The three levels focus on the difference, and the next level of content can be regarded as the foundation of the content of the next level, which deserves more attention. To reach
