Genetic Yield Improvement in Soft Red Winter Wheat in the Eastern United States from 1919 to 2009

Periodic evaluation of breeding progress is necessary to assess genetic gains over time, and underlying traits responsible for yield gains can direct future breeding. This study was conducted to determine the rate and magnitude of yield progress in eastern soft red winter (SRW) wheat ( Triticum aestivum L.) cultivars released from 1950 to 2009 relative to a historical cultivar Red May (1919). The effects of agronomic, morphological, and yield...
