摘要
通过对9份XGY高油玉米自交系生育期、产量性状和品质性状的初步分析。结果表明,9个XGY高油玉米自交系的脂肪和蛋白质含量的平均值低于3个高油自交系的平均值,差异极显著。9个XGY高油玉米自交系的淀粉含量平均值,极显著高于3个高油自交系的平均值。按生育性状,9个XGY高油玉米自交系同3个高油自交系的生育期相近,都能适应当地种植。生育期、植株性状、产量性状和品质性状综合分析,XGY003、XGY047、XGY070三个XGY高油玉米自交系与3个高油玉米自交系的形态性状有差距,但差异不显著,基本上符合高油玉米自交系的要求,可以直接与其它高油自交系或普通玉米自交系组配杂交种。大部分的XGY高油玉米自交系穗部性状没有常用的3个高油玉米自交系的穗部性状优良,有待进一步改良。
The preliminary analysis was based on the nine types XGY high oil maize inbred lines＇ growth,yield and quality traits.Result indicated that average of fat and protein content in these inbred lines was inferior to average of three high oil maize inbred lines.Difference was extremely significant.The average of starch content in the nine high oil maize inbred lines were higher than that of three high oil maize inbred lines.The 9 XGY high oil maize types has similar growth period with the three high oil maize inbred lines,so they were adapted to local planting.Integrated analysis of growth period,growth,yield and quality traits showed that the growth traits of＇XGY003＇,＇XGY047＇,and＇XGY070＇were different from the three control lines,but difference was not significant.So they were basically meet with high oil maize inbred lines＇ requirements and they can directly be matched with other high oil maize and ordinary inbred lines to breed hybrids.Most of the XGY high oil maize inbred lines＇ spike traits were not fine than these three commonly used high oil maize.It required further improvement.
