业已证明,普通小麦(Triticumaestivum.L,Zn—6x—42,AABBDD)是由四倍体小麦(T.t。pomL.Zn—4x—28,AABB)和节节麦(AesilOPstauschiiCossonZn—Zx—14,DD)杂交,经染色体加倍而成。因为普通小麦的原始亲本种四倍体小麦和节节麦中存在着丰富的优良遗传变异,把这些
It has been demonstrated that Triticum aestivum L. (Zn-6x-42, AABBDD) is composed of tetraploid wheat (T.t.pomL.Zn-4x-28, AABB) and AesilopstauschiiCossonZn-Zx- DD) hybridized by chromosome doubling. Because there is a wealth of good genetic variation in the tetraploid and nodule cultivars of common wheat, the original parental species, these
