以节节麦为母本,普通小麦为父本,在添加附加成分的N6基本培养基上,培养杂种幼胚,再分别用亲本连续进行置换回交,获得核质杂种.试验结果,节节麦细胞质对普通小麦品种的农艺性状没有产生不良影响,株高似有增加,穗子略为变长,千粒重普遍增加,幅度为1-3.71克.此外,核质杂种表现出较强的抗早衰能力. In the experiment, the hybrid wheat was used as female parent and common wheat was used as male parent, hybrid embryos were cultured on N6 minimal medium with additional ingredients, Wheat cytoplasm had no adverse effect on the agronomic traits of common wheat varieties, plant height appeared to increase, ears a little longer lengthened, 1000-grain weight generally increased, amplitude ranged from 1-3.71 grams. In addition, nuclear hybrids showed strong anti-premature decline ability.
