在小麦遗传育种中,用远缘杂交法将黑麦的整套染色体组加入到小麦属中,成功地育成了六倍体和八倍体小黑麦.但黑麦的整套染色体进入小麦后,其染色体上携带的有害基因也被带了进去,所以人工合成种小黑麦虽在抗逆性上有了改进,但某些主要经济性状受有害基因影响,应用上受到了限制.近年来,许多育种工作者都重视用小黑麦与普通小麦进行杂交育种.因为六倍体和八倍体小黑麦的染色体组型分别为AABB In wheat genetic breeding, the whole genome of rye was added into the genus Triticum by distant hybridization, and hexaploid and octagonal tritium were successfully bred.When the whole chromosome of rye entered the wheat, Chromosomes carry harmful genes are also brought in, so synthetic triticale has improved resistance, but some of the major economic traits affected by harmful genes, applications have been limited in recent years, many Breeding workers attach great importance to cross-breeding triticale and common wheat because the chromosomes of hexaploid and octa-triticale are AABB
