Abstract: The successful breeding on the development of three neucleo-cytoplasm substiturion lines NC3, NC4 and NC37, in which the cytoplasm was from Ae. tauschii (D) and the neuclear was from common wheat variety Fengkang13, was taken as examples to elaborate the methed of neuclear substitution, the characterization and application of bybrid superiority produced by neucleo-cytoplasm interaction. It was proved that neucleo cytoplasmic bybrid might be a effective way to take wheat hybrid superiority into use stably. By review the study history around the world in this field, the potential and prospect of utilization of alloplasmic wheat line in creating neucleo-cytoplasmic bybrid, improving wheat variety with stress-tolerence or biostress-resistance and good quality, breeding hybrid wheat by using D2-type cytoplasm and two-line-method were forecasted.
