Abstract:

Fragrance is a very important quality traits of rice, fragrant rice research has been an important research issue in rice research fields in nowadays. In our study, using the detection method of molecular markers, genotypes of the 10 genes (Wx, SSII3, SBE3, AGPiso, SSIII2, AGPlar, PUL, SSI, ISA, SSIV2) associated rice eating quality were analyzed in the 23 fragrant rice cultivars. The result indicated that the “2845”rice cultivar possesses the best combination of genotypes related to the highest eating quality, and the next best rice cultivars were “Songxiangzaojing”, ”Suhuxiangjing”, “B1”, “Wuyun2645”, “Tongyunjing”, “Yinxiang28”, “Xiangjing49②”, “99983”, “Wxiang99075”, “07-08”, “Yunjingyou15”, “29185”, “Nanhai318”. Other 9 rice cultivars (“Dahuaxiangjing”, “Wuxiang14”, “Xiangjing”, “Della”, “Dalixiang”,  “Taiguoxiangdao”, “Cxiang517”, “Xiangdao No1”, “Zhongxiang No1”) obtain some of bad genotypes which may have adverse effect on rice eating quality. This study was helpful to establish an overall understanding of the genotypes of these ten eating quality related genes in the 23 tested fragrant rice cultivars, and provides the important genotype information in selecting and cultivating new fragrant rice with good eating quality in future via molecular markersassisted selection method.
