摘要: 基于探究不同肥力水平对小麦(Triticum aestivum L.)性状表达的影响,为小麦DUS测试工作提供参考,以4份普通小麦品种为试验材料,设置5个施氮量处理,对32个DUS测试性状的表达进行分析。结果表明,不同施氮水平对芒长的表达影响较大,表现出2个代码差异,而质量性状、假质量性状及其他目测型数量性状的表达无差异或相差1个代码;方差分析结果显示,施氮量对不同测量型性状在品种间的影响程度不同,各性状在不同肥力下均表现出显著差异(P<0.05),其中旗叶长、旗叶宽和穗长的表达受施氮量的影响较大,株高、小穗数、穗粒数等性状的表达受影响程度较小,不育小穗数的表达基本无影响。

Abstract: To explore the effects of different fertility levels on the expression of wheat (Triticum aestivum L.) traits, so as to provide reference for wheat DUS test, using 4 common wheat varieties as materials, the expression of 32 characters in DUS test was analyzed by setting 5 nitrogen application treatments. The results showed that different nitrogen application levels had a great influence on the expression of awn length, showing two code differences, while there was no difference or one code difference in the expression of quality traits, false quality traits and other visual quantitative traits. The results of variance analysis showed that the effect of nitrogen application on different measurement type traits among different varieties was different, and each trait showed significant differences under different fertility(P<0.05). Among them, the flag leaf length, flag leaf width and spike length were greatly affected by the amount of nitrogen fertilizer, the expression of plant height, spikelet number and grain number per spike were less affected, and the expression of sterile spikelet number was basically not affected.

Key words: common wheat (Triticum aestivum L.), nitrogen application rate, the expression of character, DUS testing
