Title: Construction of Rice Core Germplasm Breeding System
Abstract: Super high yield rice breeding in China was reviewed.The super rice breeding was divided into two stages,including super high yielding rice breeding and super rice breeding.The construction of rice core germplasm breeding system was demonstrated from theoretical system and breeding materials.The rice core germplasm breeding system was the combining outcome of rice breeding theory and practice.The rice core germplasms were breeding materials with some excellent characters,controlling some excellent characters by special gene community or gene system,replacing along the breeding goals in process of quality improvement,and expanding gene community until comprehensively accorded with the breeding goals.The platform for rice core germplasm breeding was constructed(research for yield character breeding).Heredity breeding was studied in four parts,including hereditary evolvement of the rice core germplasm,research for ideal hereditary model,molecular breeding of effective yield gene and the discovery of high yield gene from cultivated rice and wild rice,and root biology breeding.
