本文通过对河北省玉米杂交种发展历史的回顾与现状分析,预测了未来生产对玉米杂交种的要求,并试拟了河北省玉米杂交种的发展战略,即要以种质资源的征集,改良和利用为基础,以大幅度地提高单产为前提,实现局部高产与大面积均衡增产的结合,高产与稳产、高产与优质的结合,高产与低成本高纯度的结合和品种配套与合理布局的结合。
Based on the review and current situation of the development history of maize hybrids in Hebei Province, this paper predicts the future requirements of maize hybrids and attempts to develop the development strategy of maize hybrids in Hebei Province. That is, we should take the collection of germplasm resources, And utilization as the basis, in order to substantially increase yield as a precondition to achieve a combination of local high yield and large-area balanced production, high yield and stable yield, high yield and high-quality combination of high-yield and low-cost high-purity combination and variety of supporting and rational distribution Combined.
