Molecular studies on new resources for hybrid rice breeding
update：2020-06-16
Features
F1 hybrid breeding is one of the most advanced techniques for production of cultivars with higher yield and desirable traits of both parents. 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.Targeted Application(s)/Industry
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.Researchers
