摘　　要：节节麦是六倍体普通小麦的祖先种之一,D染色体组的供体种;但其遗传变异远比普通小麦的D染色体组丰富。由于节节麦的优异基因可以通过与小麦远缘杂交, 染色体同源配对、基因交换的方式转育至现代高产小麦中, 因而越来越受到育种家的重视。本文综述近20年来国内外对节节麦遗传评价、研究应用等方面的进展。同时, 报道了本课题组近年利用生物技术转育节节麦优良基因, 培育优质、抗小麦新品系(种) 方面的进展。Aegilops tauschii is D genome donor of common wheat,and the useful genes of Ae.tauschii can be easily transferred into modern commercial wheat by gene combination.However,the genetic variability of Ae.tauschii is much richer than that of D genome in common wheat.So Aegilops tauschii is a valuable source of genes for the modern common commercial wheat development.More than 20 year's research works of evaluation and utilization on Ae.tauschii were summarized in this paper,and the recent advances on gene transfers from Aegilops tauschii into modern commercial wheat by modern biotechnology in our research program were also reviewed.
