摘要
通过对广东优质籼稻品种抗瘟性研究、抗病品种的系谱分析以及抗病育种实践的回顾,综述了广东优质稻抗性育种历史及现状,剖析了优质稻抗瘟育种存在的问题及相应对策。提出开发利用不同稻作系统的抗病资源,构建遗传多样性丰富的抗病优质种质,延长品种抗性寿命及解决品种优质与抗病的矛盾。
The history and the current status of the blast resistance breeding of fine quality indica rice in Guangdong, South China were reviewed, and the challenges and the strategies in the resistance breeding in the future were discussed. Utilization of the resistant resources from different rice system was recommended to enhance the diversity of genectic background for resistant varieties in the rice breeding program. Development of new resistance germplasm with fine quality and diverse background is an effective and prior way for extending the durability of the resistance of fine quality indica rice and alleviating the contradiction between quality and resistance in South China.
