High quality is one of the most objectives in rice breeding, and introducing and evaluating the quality of rice germplasm are very important for screening novel parent with high quality and breeding high quality varieties. In this study, a total of 28 rice germplasm from Africa and Brazil were evaluated their milling quality, appearance quality and cooking and eating quality in Wuhan City, Hubei Province. The results showed the milling quality and appearance quality of most varieties were very high, but the cooking and eating quality of them were bad. Finally, 13 varieties with high quality were screened. The correlation analysis indicated that different traits among milling quality, appearance quality and cooking and eating quality had low correlation between each other. Further, all germplasm was genotyping three important quality genes, GS3, Wx and ALK. There were two genotypes in each of GS3 and Wx, and ALK had three genotypes. The phenotypes showed significantly difference between different genotypes for both Wx and ALK. Our results will give valuable germplasm resources, gene resources and marker resources for breeding high quality rice varieties.
