| Abstract: | The observation results show that the single-plant of photo-thermo-sensitive genic sterile line “635s” has long flowering duration (15.5d on average) and obvious peak flowering period (on the 5th～10th day after heading); during peak florescence, the glume can flower at 6∶00～19∶00 in a day, and one peak flowering occurs at 11∶00～13∶00， sometimes the other peak flowering appears at 7∶00 or so; the rate of outshowing stigma of “635s” is 73.7%, its setting rate of outcrossing is 59.1%， and the opening time of the glume is 2.13～3.25h. |
