【摘要】 对Ｎ５０４７Ｓ、Ｎ５０４７－１Ｓ、Ｎ５０８８Ｓ、ＮＢ１４０１８Ｓ４个光敏核不育系在云南省不同地点不同海拔高度进行不同播期的繁殖试验，指出了４个光敏核不育系在云南理想的繁殖地点和播期。
【Abstract】 Four the PGMS lines,N5047S、N5047- 1S、N5088S and NB14018Swere studiedfor themulti-Plication at different elevations in Yunnan Province,It was found that Yuxi with the elevation of 1630m wasthe best place to multiply N5088S, and its suitable seeding date was on 30 March and the highest seed settingpercentage reached 76.9%. In Yuanjiang, with the elevation of 400m, all 4 PGMS lines can be multiplied inthe late cropping season and the highest seed yield was obtained in NB14018S at 6.34t/ha.
