  1. WH017JPC = Correlation was computed using genotypes LS means for WH score recorded in 2017 at UGA JPC farm
  2. WH-JPC = Correlation was computed using genotypes LS means for WH score recorded for overall (3 years) at UGA JPC farm
  3. WH017BVL = Correlation was computed using genotypes LS means for WH score recorded in 2017 at UGA Blairsville farm
  4. WH-BVL = Correlation was computed using genotypes LS means for WH score recorded for overall (3 years) at UGA Blairsville farm
