From 1970 to 1979, Xuzhou 7471 was crossed with Mexican Ye-cora F-70 as female parent and Xuzhou 32331 as male parent through sexual selection and continuous selection. In Huaibei area of this province, after many years of trial, demonstration and Large-scale test results, the performance of early maturity, high yield, rust resistance, high quality, better overall characteristics. First, the characteristics of semi-winter. Tillering strong, spike number of more than 80 cm tall leaves small and very small, Plant type is loose, thin stem tough, looks handsome. Generally less than 700 pounds per mu yield, not easy to lodging. Spindle spindle, Changmang, white light. White, horny. Spike 25 ~ 30 grains on average.
