大豆锈病研究进展

1899年在中国的吉林首次报道了由豆薯层锈菌(Phakopsora pachyrhizi Syd)引起的大豆锈病。20世纪60年代大豆锈病成为热带、亚热带地区大豆生产中最严重的病害，进入本世纪后，大豆锈病成为世界性病害。对大豆锈病较为系统的研究始于20世纪70年代，目前对大豆锈病的病原菌分类、分布及其寄主、病原夏孢子生物学特性、病害流行、抗锈资源鉴定、抗锈遗传都有较为详细的研究，但对冬孢子的作用、生理小种的分化和鉴定、锈菌的交替寄主、锈病的初侵染源都还缺乏深入的研究，至今尚未发现对锈菌免疫的抗源，限制了锈病的防治和抗锈遗传育种的开展。

The status of soybean rust research

Soybean rust caused by Phakopsora pachyrhizi Syd was first reported in 1899 in Jilin in northeast China.It became the most destructive disease for soybean production in tropical or sub-tropical areas since the 1960s,and is a world-wide disease nowadays.Systematic research on soybean rust was initiated in the 1970s.The pathogen distribution,host range,pathogen biological characteristics,disease epidemiology,host resistance identification and screening,genetics of rust resistance and breeding,integrated management have been addressed.
