为了使小麦杂种优势利用的研究取得突破性的进展,非常需要寻找新的雄性不育细胞质来源。有人推测以节节麦(Aegilops squarrosa)细胞质为基础,培育不育系的生产杂交小麦新体系,可能是较为理想的。然而,因为节节麦-小麦核质杂种都是可育的,虽然通过诱变处理得到个别雄性不育突变体,但至今还没有得到理想的隐性基因控制雄性不育材料。 In order to make breakthroughs in the utilization of wheat heterosis, it is necessary to find new sources of male sterile cytoplasm. It is speculated that based on Aegilops squarrosa cytoplasm, it may be more desirable to cultivate male sterile lines for the production of new hybrid wheat lines. However, because Arthropodaceae-wheat nuclear hybrids are fertile, individual male-sterile mutants have been obtained by mutagenesis, but so far no ideal male sterility-controlling male sterility material has been obtained.
