Abstract

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.
