Abstract:
In this study, in order to select the suitable autumn planting maize varieties in Fujian, we introduced a lots varieties of maize from different ecological types, and tested them through years and multi-point testing in the autumn.Moreover, we carried out the correlation and path analysis of the main quantitative characteristics and yield on maize, in order to study the method of breeding high yield of autumn planting maize.The results showed that denghai3622, derui29and sushi50103had high and stable yield and good resistance adapted to autumn planted in Fujian.In the strategy of breeding high yield autumn planting maize, it′s important to select the varieties of resistant to south-rust disease, and take into account of ear length and hundred-grain weight increase. Furthoremore, the growth season for maize should moderate, but the long growth season is not inadvisable.
