摘要
两系杂交水稻在生产上已大面积推广应用,但其种子生产却存在较大的风险。从光温敏不育系自身特性及种子生产技术方面分析了影响两系杂交水稻种子质量的因素,提出了提高两系杂交水稻种子质量的对策。
Two-line hybrid rice has been widely used in commercial production. However, a higher risk might oc- cur in its hybrid seed production. The factors influencing seed quality of two-line hybrid rice were analyzed from the aspects of the characteristics of PTGMS lines and the techniques of hybrid seed production, and the corresponding countermeasures were put forward to improve and ensure a high seed quality of two-line hybrid rice.
