| 摘 要： | 云南南亚热带生态区位于北纬24°以南及金沙江河谷低海拔地区,地理位置特殊,地形地貌复杂,立体农业生态气候明显,光、热、水资源丰富但分布不均。春、夏、秋、冬一年四季均可种植玉米,但仍以夏玉米为主。根据该区复杂的生态环境、自然条件和种植习惯,提出了较高产但稳产、抗病、抗逆、适应性广、优质和大穗等玉米育种目标。

| Abstract: | The ecological area of south sub-tropical belt in Yunnan is located in the south of north-latitude 24°and at the Jinsha river bottom. There is a special area that a solid agricultural ecological climate is very obvious and sunlight, heat and water resource is very rich, but uneven distribution. The maize could be planted in spring, summer, autumn and winter, but more frequently in summer. This essay developed high-steady production, anti-pathological changes, resistance, adaptability broad, high-quality and big ear etc. |
