  1. homo homozygous resistant, het heterozygous, P present, A absent
  2. adonor for Hessian fly resistance (H) gene and chromosome mapped to
  3. bplants were counted as het if they had both dead and live larvae
  4. Numbers in parentheses represent percent plants showing presence of necrotic lesions on leaf surface
  5. Bold font indicates 100% homozygous resistant lines
