Castella

Soft White Club Wheat

Castella is a tall, awnless soft white club wheat, developed by the USDA-ARS and WSU from a diverse pedigree. Castella combines better stripe rust resistance than ARS Crescent with better test weight and higher grain yields than Bruehl. Castella has good club wheat quality, high test weight, and good resistance to low falling numbers, similar to ARS Crescent. Castella is earlier maturing than other current club wheat cultivars and combines unique resistance to Hessian Fly with aluminum tolerance. Castella is competitive in central WA where early maturity is an advantage.
