Genetic Yield Gains of the CIMMYT International Semi‐Arid Wheat Yield Trials from 1994 to 2010

Genetic progress for yield has been assessed globally in the semi‐arid wheat yield trials (SAWYTs) of the International Maize and Wheat Improvement Center (CIMMYT) over a 17‐yr period. Grain yield expressed as a percentage of the long‐term check cultivar Dharwar Dry has increased at approximately 1% yr −1 between 1994 and 2010. In real terms, yield has been increased at a rate of 31 kg ha −1 yr −1 . The rate of yield increase in high‐yielding...
