High quality is one of the most objectives in rice breeding. Introduction and evaluation of the quality of rice germplasm resources is of great significance for selecting high-quality rice parents and breeding high-quality rice varieties. In this study, 28 rice germplasm resources were introduced from Africa and Brazil, and their quality was evaluated in Wuhan, Hubei Province. The results showed that the processing and appearance quality of these germplasm resources were excellent, but the cooking and eating quality were poor. Finally, 13 varieties with high quality were screened out. The correlation analysis of different quality traits showed that the correlation among processing quality, appearance quality, cooking and eating quality was low. The genotypes of GS3, Wx and Alk were identified. It was found that both GS3 and Wx contained two genotypes, and Alk contained 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.
