Drought is one of the most important constraints of rice production in China. We are initiating a program with the long-term goal to improve the water-efficiency of rice production in China. The objectives of the program are to improve tolerance of lowland cultivars and hybrids to reduced water supply by incorporating germplasm. from upland rice varieties, and to increase the yield potential of upland rice varieties. Molecular markers will be used to identify loci for drought tolerance. Molecular marker-based strategies will be formulated on the basis of genetic analyses, and practiced in the breeding program.
