Abstract
Two experiments were conducted to investigate silicon (Si) content in a group of rice cultivars. Ten cultivars were grown in the greenhouse under three levels pf Si fertilization on a Si‐deficient Histosol. In a second experiment, 18 ‘cultivars were grown at three field locations which varied in plant‐available soil Si. In both experiments, cultivars varied in their percentage of Si in rice straw. There was no significant (P > 0.10) genotype by environment interaction. The genotypes with the greatest and lowest percentage of Si were consistently so over all Si environments and treatments.
