  • Determine heritability constants for superior tree and nut characteristics;
  • Develop host plant resistance to control pecan insects and diseases;
  • Effectively collect, document, preserve, evaluate, enhance, and distribute pecan and hickory genetic resources as part of the National Plant Germplasm System.
