摘要/Abstract

摘要：

选取23种香型水稻品种为供试材料，利用分子标记检测方法，进行了10个与稻米食味品质相关基因：Wx、SSII3、SBE3、AGPiso、SSIII2、AGPlar、PUL、SSI、ISA、SSIV2 的基因型分析。结果发现，含有最好食味品质基因型的水稻是“2845”；其次是“松香早粳”、“苏沪香粳”、“B1”、“武运2645”、“通运粳”、“银香28”、“香粳49②”、“99983”、“W香99075”、“07-08”、“云粳优15”、“29185”、“南海318”；另外9种香稻，“大华香粳”、“武香14”、“香粳”、“Della光身稻”、“大粒香”、“泰国香稻”、“C香517”、“香稻1号”、“中香1号”都分别含有一些可能会影响稻米食味品质的基因型。开展本研究不仅能够使人们对这些香稻食味品质基因型有一个全面的认识，还可为今后利用分子标记辅助培育优良食味品质香稻新品种和亲本的选择提供重要的基因型信息。

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.
