利用近红外光谱仪对2013年海南三亚种植收获的99份温带自交系(13份高油材料和86份普通材料)、64份热带/亚热带自交系和由这163份自交系随机组配的186份杂交组合的杂交当代F0材料进行无破损子粒品质成分鉴定,分析不同生长带玉米自交系及其不同组合的杂交种后代品质成分的差异性。结果表明,当不考虑高油材料影响时,温带材料与热带/亚热带玉米自交系之间粗蛋白、粗脂肪和粗淀粉含量差异均不显著;去除高油材料后,温带材料与热带/亚热带玉米自交系之间粗蛋白差异不显著,粗脂肪和粗淀粉含量差异极显著。对于不同生长带玉米杂交当代F0而言,考虑与不考虑高油材料影响时,粗脂肪差异都极显著,粗淀粉和粗蛋白都无明显差异;相对于粗蛋白和粗淀粉,粗脂肪表现出更高的超高亲和超中亲优势。
Ninety-two temperate inbred lines (13 high oilseeds and 86 common materials), 64 tropical / subtropical inbred lines, and 163 inbred lines harvested from Sanya, Hainan were analyzed by near infrared spectroscopy The hybrid F0 material of 186 hybrid combinations was used to identify the quality components of non-damaged kernels, and to analyze the differences of the quality components among the progenies of hybrid inbred lines with different growth zones and their different combinations. The results showed that there was no significant difference in the content of crude protein, crude fat and crude starch between temperate and tropical / subtropical maize inbred lines when the effect of high oil content was not considered. After removal of high oil content, the difference between temperate and tropical / subtropical maize inbred lines There was no significant difference in crude protein between maize inbred lines, but significant difference in crude fat and crude starch content. Crude fat showed significant difference with or without considering the effect of high-oil material for the different F0 growing maize hybrids, and there was no significant difference between crude starch and crude protein; compared with crude protein and crude starch, crude fat showed Higher ultra-high affinity and super-middle-superiority.
