摘　　要：从国际水稻研究所引进了一套籼稻微核心种质,对其中25份种质资源进行了富硒处理并考察了外观品质。结果表明,与对照相比,富硒处理对粒型基本没有影响,但能明显降低籼稻的垩白粒率与垩白度。但是不同品种的垩白性状对富硒处理的反应差异较大,在富硒处理条件下,垩白粒率与垩白度提高的品种有7个,降低的有17个。因此,在大面积生产富硒水稻时应先筛选在富硒条件下垩白粒率和垩白度不提高的品种。25 indica varieties introduced from International Rice Research Institute were planted at selenium-rich and CK conditions, and their appearance quality was tested. The results showed that there was no difference of grain shape between selenium-rich condition and CK condition, while chalkiness grain rat and chalkiness degree was decreased at selenium-rich condition. The responses of different varieties on chalkiness for selenium-rich were different. At selenium-rich condition,chalkiness grain rat and chalkiness degree of 7 varieties increased, while that of 17 varieties decreased. So farmers must screen suitable varieties before selenium-enriched rice production.
