Genetic Gain in Yield Attributes of Winter Wheat in the Great Plains

Knowledge of changes associated with advances in crop productivity is essential for understanding yield‐limiting factors and developing strategies for future improvement. Our objective was to identify plant traits associated with gains in grain yield of winter wheat ( Triticum aestivum L.) in the Great Plains. Twelve landmark cultivars and one experimental line were compared with ‘Turkey’ (introduced 1873) at Hutchinson (Clark‐Ost complex soil)...
