This trial series was established in 2004 to identify and rank rust resistant seed orchard parents in Seed Orchard 219, which provides seed for the Bulkley Valley low elevation Seed Planning Unit (SPU). Results will allow collection of custom seedlots with resistance to comandra rust. Five test sites were established in areas of high rust incidence. One hundred and thirty seedlots were included, focusing on families represented in Seed Orchard 219, located at the Vernon Seed Orchard Company (VSOC) orchard site. Trial assessments in 2006 and subsequent years will allow collection of resistant seedlots for deployment in disease-prone areas, possibly beginning in 2006.
