【Abstract】 During the past 8 years′ research, the technique of cultivation and management in sugarcane crossing parents and photoperiod inducing technique have been mastered in subtropical region. The flower-induced rate has been raising year by year and some shy-flowering parents have been induced to flower. With sexual hybridization, some valuable clones and middle material have been gained. In the meantime, the work of distant-hybridization has been performed, and a few acheivements has been gained. At the last, the auther summarized the achievement and disadvantage in the research and pointed out the researth direction in the future.更多还原
