| 摘 要： | 利用FOSS公司1255型近红外透射光谱分析仪,对2000～2001年的686份玉米自交系和2001～2004年的2517份杂交组合的子粒品质成分进行测定。结果表明,玉米子粒3种品质成分在不同材料间存在显著差异,粗脂肪和蛋白质变异幅度和变异系数较大,粗淀粉含量的变异幅度和变异系数较小,年份之间有差异。自交系中粗脂肪平均含量为4.24%～4.27%,蛋白质平均含量为11.75%～12.17%,粗淀粉平均含量为71.04%～71.10%。玉米杂交组合粗脂肪平均含量为4.45%～4.86%,粗蛋白平均含量为9.65%～10.05%,粗淀粉平均含量为72.53%～73.49%,并对玉米品质育种和近红外技术的利用作了探讨。

| Abstract: | NIRS was a new method for quality analyzer in crop breeding.The kernel quality of 686 maize inbred lines in 2000-2001 year and 2 517 cross combinations in 2001-2004 year were analyzed in this paper by using near infrared spectroscopy transmission(NIT) analyzer,which was made by FOSS Company.The heterosis of crude-fat,protein and crude starch in corn kernel and the relativity between hybrids and their parents was discussed too.It showed that the range of variation and the coefficient of variation were larger for crude-fat and protein content,the variance range and the coefficient of variation of crude-starch were lesser,the average content was 4.24%-4.27%,11.75%-12.17% and 71.04%-71.10% respectively for the crude-fat,protein and crude-starch in inbred lines,and was 4.45%-4.86%,9.65%-10.05%,and 72.53%-73.49%,72.56%-72.74% respectively in cross combinations.The corn quality improving and the application of NIRS were discussed in the paper. |
