Interpretive Summary:

Technical Abstract: The Collaborative Oat Research Enterprise (CORE) panel of elite lines remains a useful resource for investigating the genetic architecture of complex oat traits and for identifying quantitative trait loci. In 2010, 2011, and 2017 lines were evaluated at multiple locations for the milling quality-related mature seed characteristics summarized by measures of test weight, thousand kernel weight, groat content, the percent of groats broken during de-hulling, and percent of plump and thin kernels. In 2018, many of these lines were evaluated at the National Plant Phenomics Centre, Aberystwyth, UK for seedling growth under soil moisture contents of 25%, 35%, 75%, and 105%. Together, these sets of phenotypic data allow us to examine the genetic architecture of quantitative traits from both ends of the oat plant’s life, and to identify QTL influencing trait variation per se as well as QTL influencing trait stability across environments.
