继籼型水稻光温敏雄性不育系衡农S—1育成之后,我们又选育出一类新的籼型水稻光温敏不育系;87N13、87N10、87N123—R6。衡农S—1在较高温长日照下不育,在较低温短日照下可育,而87N13、87N10、87N123—R6恰恰相反,在较高温长日照下可育,在较低温短日照下不育。我们把前者叫做正
Following the breeding of Nongnong S-1, a new type of Indica rice thermo-photo-sensitive genic male sterile line, we also breed a new type of indica rice photo-thermo-sensitive genic male sterile line 87N13, 87N10, 87N123-R6. Hengnong S-1 was sterile under higher temperature and long day sunshine and fertile at lower temperature and shorter day, while 87N13, 87N10 and 87N123-R6 on the contrary, were fertile at higher temperature and longer sunshine and at lower temperature and short day Education. We call the former positive
