Field experiment was conducted to study the response of 12 early rice cultivars of Hainan province to foliar appli- cation Na2SeO3 .The result showed that compared with control，average selenium（Se）content in brown rice and polished rice was improved through foliar application Na2SeO3 by 43% and 34%，respectively.And the differences was significant （p<0.01）.Various rice cultivars had different response to Se spraying.Compared with control，Se contents of brown rice of Congyou 629 and Teyou 5735 were significantly improved by Se spraying.Therefore the two rice cultivars could be choose to produce enriched-Se rice in the soil with low Se content of Hainan province.
