摘要
近年来,国家对"镰刀湾"地区种植业结构进行战略性调整,减少非优势区玉米种植面积,恢复和增加大豆种植面积,特别是大力发展东北高寒地区特早熟大豆生产。国内外学者在特早熟大豆农艺性状、熟期划分及品种选育方面进行了大量研究。文章从我国特早熟大豆发展的意义、特早熟大豆生态特征、育种目标及品种选育等多个方面对前人研究进行了综述,探讨了育种的方法和方向,以期为特早熟大豆育种、栽培工作提供借鉴。
In recent years,Chinese govemnmnt had bean made strategic adjustments to the planting structure in the Sickle Bay- area, in order to reduce corn planting area and increase soybean planting area, especially developing the early maturity soybean production in the north-eastern high-cold area. Scholars had bean done a lot of researches on the agronomic traits, ripening period, and variety- breeding of early-season soybeans. The previous studies on the early maturity soybean in significance of the development, ecological characteristics, breeding objectives and variety- breeding in China were summarized and the breeding methods and direction were investigated in order to provide reterence tor breeding and cultivation of early-maturing soybeans.
