利用普通小麦与八倍体小黑麦杂交,培育出形态学似普通小麦的次级六倍体(Sec-ondary hexaploid),是目前广泛开展的一项研究。国外,早在1939年 M(?)NTEiNG就论述了八倍体小黑麦与普通小麦杂交后代的细胞遗传,植株生活力,育性等。之后,对于小麦与小黑麦杂交后代细胞遗传的研究相继有些报道。在国 Sec-ondary hexaploid, which is morphologically similar to common wheat, is crossed with the hybrid of common wheat and octoploid rye, and is a widely studied study. Abroad, as early as 1939, M? NTEiNG discussed the cytogenetics, plant viability, fertility and other aspects of the offspring of the hybrid between twenty-eight triticale and common wheat. Later, there have been some reports on the cytogenetic studies on the offspring of wheat and triticale. In the country
