Cytological observation of anther structure and genetic investigation of a thermosensitive genic male sterile line 373S in Brassica napus L

Photoperiod and/or thermo-sensitive male sterility is an effective pollination control system in crop two-line hybrid breeding. We previously discovered the spontaneous mutation of a partially male sterile plant and developed a thermo-sensitive genic male sterile (TGMS) line 373S in Brassica napus L.
