2013—2024年福建省审定水稻品种的品质状况研究

Quality Status of Rice Varieties Approved in Fujian Province from 2013 to 2024 

  • 摘要: 为探明福建省审定水稻品种稻米品质的现状及其变化趋势,对2013—2024年审定的475个水稻品种组成进行了统计与分析,探究了其中439个籼型食用稻品种的品质状况及其变化趋势,以期为今后水稻品质改良育种提供参考。结果表明:随着时间的推移,水稻稻米品质显著提升,早、中、晚稻品种中优质稻比例及部分米质性状达标率有较大幅度提高,其中早稻和中稻整精米率明显提高、垩白度明显降低;晚稻垩白度 明显降低。因此,今后在水稻品质育种中要筛选整精米率高、垩白度低及碱消值达到优质等级的材料,有利于水稻稻米品质的改良和提升。

     

    Abstract: In order to preliminarily explore the status and changes of rice quality of rice varieties approved in Fujian Province, statistical analysis was conducted on the composition and structure of 475 rice varieties approved in Fujian from 2013 to 2024, with a focus on analyzing and studying the rice quality status and changes of 439 indica edible rice varieties, in order to provide reference for future rice quality improvement breeding. The results showed that over time, the quality of rice significantly improved, with a significant increase in the proportion of high-quality rice and the compliance rate of some rice quality traits. Among them, the head rice rate of early and mid-season rice significantly increased, and the chalkiness degree significantly decreased. The chalkiness of late rice also significantly decreased. Therefore, in rice quality breeding in the future, it is necessary to screen materials with high head rice rate, low chalkiness, and alkali digestion value reaching high-quality levels, which is conducive to improving rice quality.
