1,Gene/QTL discovery, allelic mining and molecular breeding for traits of agronomic importance in rice;
Resistances/tolerances to abiotic stresses (drought, salinity, low temperature, etc.);
Resistances to biotic stresses (blast, bacterial blight, sheath blight, brown planthopper, and false smut);
High yield potential, CMS restoration and heterosis.
2,Molecular breeding and trait improvement by QTL pyramiding;
Develop large numbers of introgression line (IL) sets in elite rice genetic backgrounds as the platform for large scale rice molecular breeding;
Establish high-throughput genotyping platform;
Establish the database of the genetic information (positions, effects, closely linked markers, and epistasis, etc) for genes/QTLs affecting important traits in the IL sets;
Develop and apply the theory and software for improving multiple traits by QTL designing and pyramiding.
3,Functional genomics of complex rice traits;
Discovery and functional characterization of genetic and molecular networks underlying drought and salinity tolerances in rice;
Cloning and functional analyses of important genes/QTLs affecting drought and salinity tolerances in rice;
Genetic and molecular dissection of the interaction between rice and its pathogens.
