Differential Adaptation of CIMMYT Bread Wheat to Global High Temperature Environments

A good understanding of the target environment and the extent of genotype × environment (G × E) interaction is essential for all cereal breeding programs. Differential adaptation of bread wheat ( Triticum aestivum L.) to various heat‐stressed environments around the world was analyzed by cumulative cluster analysis of locations and genotypes in 9 yr of CIMMYT's High Temperature Wheat Yield Trial (HTWYT). The grouping pattern of yield‐testing...
