Most agronomic characteristics are important in rice such as PH (plant height), HD (heading date), HR (heat-resistance) and yield components or seedling vigor .components. Both DH (doubled haploid) and RIL (recombinant inbred lines) populations were derived. A genetic map was constructed by molecular marker analysis. QTLs associated with these traits above were mapped according to the data for phenotype. At the same time, we transferred gene resistant to bacteria blight into rice on the basis of ...
