Derivatives from 4 species from the secondary gene pool of wheat-1 diploid (), 2 tetraploid (; ), and 1 hexaploid ()-were screened for resistance to Fusarium head blight, leaf rust, stem rust, and stripe rust. Where screening, genetic studies, and mapping were completed it was shown that all species carried resistance to multiple plant diseases. Some derived lines carried resistance to up to four different diseases. Where mapping was completed, it was shown that different diseases mapped to different chromosomes within any one accession.
对来自小麦第二基因库的4个物种的衍生物进行了筛选，其中包括1个二倍体（）、2个四倍体（；）和1个六倍体（），以检测它们对赤霉病、叶锈病、茎锈病和条锈病的抗性。在完成筛选、遗传研究和图谱绘制的地方，结果表明所有物种都对多种植物病害具有抗性。一些衍生系对多达四种不同的病害具有抗性。在完成图谱绘制的地方，结果表明在任何一个材料中，不同的病害定位于不同的染色体上。
