For the seamless connection between rice breeding and rice germplasm resources, and the integration of conventional breeding technology and advanced applicable technology, our team has established rice core germplasm breeding theory and material collections. The rice core germplasm breeding theory includes the conception of rice core germplasm, corresponding hypothesis of ideal gene system and groundbreaking rice varieties, creation of the ideal model, comprehensive planning of background selection and foreground selection, DNA block of biological significances, data cloud of genotypes and phenotypes of rice core germplasm, research on comprehensive rice breeding by advanced and applicable technology, heterosis utilization of rice core germplasm. Huanghuazhan, Meixiangzhan and Huazhan core germplasm breeding materials were created, as well as the variety of Huanghuazhan with the largest growing area as indica rice in China, and the variety of Meixiangzhan 2 with excellent eating quality in China, the restore line of Huazhan with excellent combining ability in rice breeding history on the basis of rice core germplasm breeding theory.
Key words： rice; core germplasm; breeding
