First, the purpose of the experiment Breeding and application of hybrid early rice is the city’s main way to develop food production. In recent years, in our hybrid rice breeding work, we have selected a better restorer line 10 to 35 and formulated a new combination with several CMS lines. This test is the new combination of yield, disease resistance, quality identification. Second, the test materials tested Shanyou 10-35, Xieyou 10-35 and control varieties Erfu. Shanyou 10-35 and Xieyou 10-35 were made in Hainan Island in winter last year, in April 25
