Crop varieties that are able to maintain consistent yields across a range of environmental stresses are of value to farmers, particularly those with limited ability to recover from crop losses. Understanding the genetic basis of trait stability across a gradient of environmental conditions will enhance our ability to develop broadly adapted, climate-resilient crop varieties.
Margaret Krause is leveraging genomic, weather and phenotypic data from trials conducted by CIMMYT’s International Wheat Improvement Network over the past four decades to better understand the genetic architecture of phenotypic stability and the effects of long-term artificial selection for broad adaptation on the wheat genome. She is funded by a United States National Science Foundation Postdoctoral Research Fellowship in Biology through the Plant Genome Research Program.
