所有79株节节麦从Kihara教授的收藏中收集的伊朗血统的材料进行了分析。在研究的23个酶编码位点中，有11个是多态的。在伊朗Ae. tauschii由ssp提出。tauschii和ssp.它们在遗传、形态和生态上都有明显的差异。低多态性位点Aco2和高多态性位点Ep在两个亚种中的变异模式相似。Acph 1、Ak、Est 2、Est 5、Got 1、Got 2、Got 3和Lap的变异是一组多样的模式，在亚种和自然区域之间也存在显著差异，这意味着自然选择参与其中。
All the 79 Aegilops tauschii Coss. accessions of Iranian origin from Prof. Kihara's collection were analyzed electrophoretically. Of 23 enzyme-encoding loci studied, 11 were polymorphic. In Iran Ae. tauschii is presented by ssp. tauschii and ssp. strangulata which distinctly differ genetically, morphologically and ecologically. Variation patterns of low polymorphic locus Aco2 and highly polymorphic Ep are similar in both subspecies. In contrast, variation of Acph1, Ak, Est2, Est5, Got1, Got2, Got3 and Lap is a set of diverse patterns which markedly differ between subspecies and natural regions also, implying that natural selection is involved.
