M型杂交大豆育种研究进展

Development of Breeding of M Type Hybrid Soybean

自 198 9年发现大豆细胞质不育材料后 ,经过连续多年研究 ,于 1997年育成 W931A等不育系 ,并实现了三系配套 ;1998- 2 0 0 3年通过回交和测交已先后育成 2 9份不育材料、4 5个恢复系及 2 7个强优组合。其中已有 2个组合参加安徽省大豆良种区域试验 ,增产显著 ;另外在制种技术上取得了显著进展。预计“十一五”

After soybean male sterile materials with CMS were found in 1989,the male sterile line W931A was selected in 1997 through mang year researches ,and then the system of three lines was set.29 male sterile materials,45 the restorer lines and 27 hybrid combinations with high yield and fine agronomic characteristics had been obtained with backcrosses and test crosses from 1998 to 2003.Two hybrid combinations with CMS entered Anhui provincial soybean regional trial and significantly increased. In addition, the technology for producing hybrid seed had also great progresses.It was expected that hybrid soybean was put in use in the late Eleven Five plan.
