环境对玉米杂交种品质性状的影响研究

以河南省生产上主要推广的15个玉米品种为材料,采用近红外光谱技术,分析了在8个不同生态环境下粗蛋白、粗淀粉、粗脂肪和赖氨酸4个玉米品质性状。结果表明:各性状在品种间、地点间和品种与地点互作间的差异均达到极显著水平。在15个品种中,HE-1、HE-2、豫单2001和豫单2002粗蛋白含量高于11%以上,赖氨酸含量高于0.35%,可作为高蛋白、高赖氨酸优质饲用专用玉米品种;郑单958、浚单20、洛玉1号和郑单18粗淀粉含量在72%以上,可将作为高淀粉工业加工专用玉米品种;HE-1、HE-2的粗脂肪含量在7.5%以上,可将它们作为高油工业加工和优质饲用专用玉米品种。驻马店、郑州和洛阳适宜高蛋白、高赖氨酸优质饲用专用玉米品种的种植;商丘、安阳和周口适宜高淀粉工业加工专用玉米品种的种植;商丘、新乡和郑州适宜高油专用玉米品种的种植。

Studies on the Effects on the Quality Characters of Hybrids Under Different Ecological Environments in Maize

The performance of four quality characters of fifteen maize hybrids under eight ecological environments was studied by using near infrared reflectance spectroscopy(NIRS). The results were that the variances of hybrids, locations and hybrids×locations were significant in four quality characters,this showed there was genetic difference in different hybrids and locations and hybrids×locations as well. The protein content of the four hybrids, HE-1, HE-2, Yudan101 and Yudan 2002 was more than 11%, and the lysine content of them was more than 0.35%.The oil contents of the HE-1 and HE-2 were more than 7.5%. The contents of protein and lysine were higher significantly in Zhumadian, Zhengzhou and Luoyang than that in any other locations. The starch contents in Shangqiu, Anyang and Zhoukou were higher significantly than that in the others. The oil contents in Shangqiu, Xinxiang and Zhengzhou were higher significantly than that of the others.
