黑麦在小麦改良中起着重要的作用。本文报道了在离体黑麦花粉经He-Ne激光照射后，由MY11 （Triticum aestivum）和荆州（seale cereale）宽杂交组合衍生出的新黑麦新品种“分枝1号”。在形态上，分枝1号的特征为分枝尖刺。遗传上，分枝1号表现出稳定的育性和对小麦白粉病和条锈病的免疫力。原位杂交（FISH）和种子贮藏蛋白电泳结果表明，分枝1号是一株新的初生六倍体小黑麦（AABBRR）。本研究不仅提供了一种新的人工合成方法，而且表明分枝1号可能是小麦改良的宝贵资源。
Rye (Secale cereale) plays an important role in wheat improvement. Here we report a new triticale, named Fenzhi-1, derived from the wide cross MY11 (Triticum aestivum) × Jingzhou (Secale cereale) after the in vitro rye pollen has been irradiated by He-Ne laser. Morphologically, Fenzhi-1 is characterized by branched-spikes. Genetically, Fenzhi-1 displays stable fertility and immunity to wheat powdery mildew and stripe rust. In situ hybridization (FISH) and seed storage protein electrophoresis revealed that Fenzhi-1 is a new primary hexaploid triticale (AABBRR). The present study not only provides a new method to synthesize an artificial species, but also shows that Fenzhi-1 could be a valuable source for wheat improvement.
