Abstract：The flowering habits of rice photo-thermo-sensitive genic sterile (PTGMS) lines 4112S and YW-2S were observed systematically. The results showed that the flowering habits of the tested rice sterile lines had following characteristics: Both of them have short flowering duration, long spikelet opening time, large full opening angle of spikelet and high stigma exsertion rate. The stigma vitality of 4112S and YW-2S was about 3d and 4d respectively. Corresponding high-yielding hybrid seed production techniques of both tested sterile lines were also discussed and recommended.
