Relationships among Bread Wheat International Yield Testing Locations in Dry Areas

Understanding the relationship among yield testing locations is important if plant breeders are to target germplasm better to different production environments or regions. To examine the relationship among international drought prone test sites, yield data from 122 locations, sown during a 6‐yr period in CIMMYT's Semi‐Arid Wheat Yield Trial (SAWYT) were analyzed. The shifted multiplicative model (SHMM) was used to group locations within each...
