| 0 | PI 658598 | 'Merl' | Triticum aestivum L. subsp. aestivum | Virginia, United States | PVPO | | Not Available | 2010 | DEVELOPED | 2009 | | | | | Cultivar | Merl is a broadly adapted, high yielding, moderately short (33.5 inches, dwarfing gene Rht2), mid-season soft red winter wheat cultivar having very good straw strength and good milling and pastry baking quality. Winter hardiness of Merl is moderate. Head emergence in Virginia (121 d, Julian) is most similar to that of Tribute . Juvenile plant growth is semi-erect. At the boot stage, Merl has yellow-green plant color and erect, twisted flag leaves. Coleoptiles are white and anthers are yellow in color. Stem internodes are hollow and peduncles are erect. At physiological maturity, it has creamy white colored straw and awnletted spikes that are tapering, recurved, dense, and creamy white in color. Glumes are long and white with rounded shoulders and acute beaks. The soft red kernels are ovate in shape with rounded cheeks and a medium brush. Phenol reaction is dark brown. Merl is resistant to powdery mildew (Blumeria graminis). It expresses an intermediate level of resistance to fusarium head blight [Fusarium graminearum (Schwabe)], leaf rust (Puccinia triticina), stripe rust (Puccinia striiformis), Barley Yellow Dwarf Virus, Septoria tritici leaf blotch, Stagonospora nodorum leaf and glume blotch, and Wheat Spindle Streak Mosaic Virus. Merl is susceptible to Hessian fly [Mayetiola destructor (Say)] and stem rust (Puccinia graminis). | 1830376 | PI 658598 |
