Most of hybrid rice utilize cytoplasmic male sterility (CMS) and fertility restoration system. We develop a Tohoku University-original CW-type CMS and fertility restorer line and study their molecular mechanism. The CW-type cytoplasm enables indica rice cultivars to be CMS, which could not be achieved by other known cytoplasm. Practical Application Hybrid rice has an average 30% yield advantage over inbred lines, and is cultivated on 13% of the world rice fields. Our study provides a new and original resource for hybrid rice breeding for globalization of rice industry.
