12 representative high quality xian/indica rice varieties were selected as test materials. Seven grain length genes including GS3, LGY3, qGL3, GL7, SLG7, TGW6and GS9, and three grain width genes including GW8, GW5 and GS5 were tested by molecular marker. The results showed that: All 12 varieties have the gs3 long-grain allele, Ezhong 5, Yujing 91, Yuzhenxiang, Huangmaozhan, Yangxizao and Super-Basimati have the GL7 and SLG7 long-grain allele, 11 varieties with the exception of Jianzhen 2 have the gw8 slender-grain allele, Yujing 91, Yuzhenxiang, 9311, R835, Huangmaozhan, Yangxizao have the GS5 Wide-grain allele. This study is helpful to establish an overall understanding of the genotypes of 10 grain-shape genes in high quality xian/indica varieties, and provides important genotype information in selecting and cultivating new high quality long-grain indica varieties via molecular marker-assisted selection in the future.
