| 摘 要： | 以448份玉米自交系为材料,对玉米全株的品质含量指标蛋白、淀粉、中性洗涤纤维(NDF)及酸性洗涤纤维(ADF)进行评价,筛选高蛋白/淀粉、低纤维的青贮玉米自交系。结果表明,在所有供试材料中,蛋白含量变化不大,淀粉含量与纤维(NDF、ADF)含量极显著负相关。以淀粉、NDF和ADF品质含量为指标,通过聚类分析,筛选出7份高淀粉(47.50%~51.20%)、低纤维(ADF为9.08%~12.93%,NDF为26.67%~31.07%)含量的青贮玉米自交系,分别为P124-3、P125-12、P128-1、P132、13634-3、12099-2和12906-1。

| Abstract: | Four traits in 448 maize inbred lines, including protein, starch, neutral detergent fiber(NDF) and acid detergent fiber(ADF) were measured to identify the high protein/starch, low fiber lines. The result showed that protein content was relatively stable in all lines, starch content was significantly negatively correlated with fiber(NDF, ADF) content. Using cluster analysis, seven maize inbred lines were identified to be with high starch(47.50%-51.20%) and low fiber content (ADF:9.08%-12.93%, NDF:26.67%-31.07%). These lines were P124-3, P125-12, P132, P128-1, 13634-3, 12099-2, and 12906-1, respectively. |
