  • Hybrid Rice Research and Development in China and Its New Progress

    <正>Hybrid rice's history and its development up to date are described in the paper. Compared with the conventional rice, hybrid rice can increase grain yield by about 20%. Hybrid rice breeding in China has been advancing along the three-line method, to two-line method, to super high-yielding rice application strategically and its success in higher degree will be seen by the utilization of distant heterosis cooperated with biotechnology.

  • Effects of Water Temperature on Male Fertility Alternation of the Sensitive TGMS Lines in Rice under the Simulated Low Air Temperature in High Summer

    <正> The effects of water temperature on male fertility alternation of TGMS lines in rice were studied under the simulated low air temperature conditions in summer. The results indicate that warm water with temperature higher than the critical temperature of TGMS lines is able to keep the lines' male sterility stable under the air temperature below the critical temperature. These results provide theoretic basis for applying warm water as an effective measure to prevent the lines from the negative effects of the low air temperature occuring in summer in the course of seed production.
