Our analysis revealed that distances between actual and predicted trait values were generally greater for commercial germplasms than for wildland populations, indicating evolutionary changes during the germplasm collection and development processes. Even when germplasm is developed under controlled standards, significant divergence from expected traits can occur. This emphasizes the need for assessing the degree to which seed transfer guidance frameworks developed for wildland populations can be used to guide seed transfer of commercial germplasms.
