ChileanJAR

Five bread wheat cultivars were selected for this study representing three diverse sources of genetic materials differing in growth habits, agronomic and quality traits. The main objective was to determine how these different gene pools responded when grown in similar environments. Wheat cultivars from Kansas, Oregon and Chile were evaluated under the environmental conditions of the Pacific Northwest (Corvallis, Oregon, 44° 30´N, 123° 30´W). Significant differences between cultivars were observed for heading date, plant height, kernel weight, and grain yield, but not for harvest index. In general, Chilean materials reached maturity later but yielded more than the other wheat. For quality traits (kernel weight, grain hardness, sedimentation volume, and grain protein), the Kansas wheat was superior to Chilean cultivars.
