玉米杂交种籽粒粗蛋白粗脂肪含量的基因型与环境互作研究初报

Genetype Environment Interaction of Crude Protein and Fat in Grain Corn

本文研究了基因型、基因型与环境互作及施肥水平对玉米杂交种籽粒粗蛋白、粗脂肪含量的影响。结果表明:不同玉米杂交种籽粒粗蛋白、粗脂肪含量存在着极显著的基因型差异及基因型与环境互作;在一定范围内,提高施肥水平可以提高籽粒粗蛋白、粗脂肪含量,但施肥水平对粗蛋白、粗脂肪含量的影响因杂交种及地点不同而异;玉米杂交种耔粒粗蛋白、粗脂肪含量受杂交种的遗传特性、栽培因素及自然条件的综合影响,应根据各地自然条件选用适宜杂交种,并采用相应的栽培措施提高籽粒粗蛋白、粗脂肪含量。

The effects of genetype,genetype×environment interaction and fe-rtility level on crude protein and fat content in kernel of corn hybrids wereinvestigated.Significant differences exist among hybrids and their interacti-on with environments.The kernel content of crude protein and fat increasesby improving the fertility level,chosing appropriate hybrids and using suit-able cultivation technique according to the natural conditions in certain locati-ons.
