Breeding of a thermo-insensitive polima cytoplasmic male sterile line YN04252A (Brassica napus L.)
YN04252A, a Polima cytoplasmic male sterile (Pol cms) line without production of pollen, was bred by means of improvement of a Pol cms line YN02A with a maintainer line 3511B although YN02A produced trace pollen under high temperture condition The investigation on the fertility of YN04252A showed that the Pol cms line was stable with 100％ plants being male sterile and 100％ sterility level for 5 years. YN04252A shared the restorer-of-fertility resource with the YN02A and had some desirable agronomic traits and a high open pollinating rate in which 86.0％ siliques were effective compared with the maintainer or restorer lines.
