  • The number and R2 range of QTL identified in the 16 environments for grain yield, heading date, and plant height are shown. The number of QTL identified in a single environment, in two environments, and across three or more environments is summarized. Results from the CIM (LOD > 2.5) are reported. Only QTL with the R2 value >1% were considered. QTL were considered common to different environments when the corresponding chromosome peak positions were located within 20 cM.
