| Abstract: | The problems such as the effect of temperature on fertility/sterility alteration, the drift of critical sterility-inducing temperature (CSIT) and the risk of two-line hybrid rice seed production were systematically reviewed in utilization of photo- and/or thermo-sensitive genetic male sterile (PTGMS) lines in rice after 1989. The causes of these problems were analyzed, and the countermeasures and technical strategies were discussed for solving these problems. |
| Keywords: | hybrid rice PTGMS line fertility/sterility alteration temperature effect drift of critical temperature risk in hybrid seed production technical strategy |
