Abstract

Core germplasm Luzhenzhan 8 (LZZ) in good quality rice was created by merging of good quality germplasm in late rice (indica) into elite germplasm in early rice (indica). Luhuangzhan, Luyuanzhan 1 and Luyuanzhan 7 were bred by further improvement of LZZ via incorporation of germplasm from Australia, japonica and wild rice into local germplasm. The approach to breeding and utilization of core germplasm in good quality rice among ecotypes, varieties from different continents, subspecies and species was discussed.
