Abstract
With the goal of researching and selecting promising hybrid maize combinations, it contributes to the selection of suitable hybrid maize varieties for Thai Nguyen province, the experiment was conducted in Spring and Winter 2018 seasons, including 07 new hybrid maize combinations and control variety NK4300. The planting techniques, tending techniques and data collection methods are implemented in accordance with the National Technical Regulation on testing for Value of Cultivation and Use of Maize varieties QCVN 01-56-2011. The results showed that the hybrid combinations in the experiment had medium growth duration (113 to 119 days in both seasons). The plant height and ear height, the EH/PLH were good. The hybrid combinations are lightly infected with stem borer and the blight disease (5.8 – 21.7%) in both seasons. The hybrid combinations CNC268 (in Spring) and MRI5 (in Winter) yielded higher the control. The MRI5 has high yield and more stable in both seasons.
