中文摘要：

为探讨环境对高油玉米品质的影响，以100个高油玉米杂交种和200个高油花粉直感的当代组合为材料，对品质性状的稳定性进行了分析。结果表明，高油玉米杂交种组合在不同年份和不同地点间的含油量差异平均为1．00％，最小为0．17％，最大相差可达1．91％，不同组合间油分变化有一定差异，即不同品种在油分性状表现的稳定性上存在差异。年份和地点效应对蛋白质含量影响的程度接近，不同年份和地点间的最大差异在1．00％左右；年份间的淀粉差异在0．4％左右，地点间的差异在1．7％左右，而单个组合在不同年份和不同地点间籽粒淀粉含量的最大差异则达到5．81％。普通玉米籽粒高油花粉直感后，在地点和年份间油分变化最大的组合其油分变化达到1．88％，最小的组合为0．37％，总体平均为1．00％；单个组合的蛋白质含量在不同年份和不同地点间的最大差异达到3．37％，最小为0．61％，总体平均为1．78％；单个组合的淀粉含量在不同年份和地点间最大相差6．21％，变化最小的组合相差0．71％，所有组合平均为2．95％。

英文摘要：

The oil, protein, starch contents of high oil corn （HOC） is influenced by environment, to estimate the stability of these components, 100 HOC single hybrids and 200 crosses of normal oil corn （NOC） seed parent pollinated with high oil pollinators （HOP） were used in the experiment. The oil content was measured by Nuclear Magnetic Resonance （NMR）, the protein and starch content was measured by Near Infrared Reflectance Spectroscopy （NIRS） . The results indicated that location effect was higher than that of year. In different years and locations, the average variation range of oil content for 100 HOC hybrids was 1.00%, the maximum and minimum were 1.91% and 0.17%, respectively. There were some differences in variation range and stability for oil content among hybrids. The average variation was 1.00% for protein content in different environments. The average variation of starch was 0.4 % in different years and 1.70 % among locations, respectively. The maximum variation of starch content for all hybrids was 5.81%. For out-crossed kernels between NOC and HOP, the average variation of oil content was 1.00% , the max/mum and minimum were l .88% and 0.37%, respectively. The average variation of protein content was 1.78% , the maximum and minimum were 3.37% and 0.61% , respectively. The average variation of starch content was 2.95% , the maximum and minimum was 6.21% and 0.71% , respectively.
