Details:

  • 58 named cultivars
  • 34 unknown cultivar matches to other samples – likely named cultivars not in ARS dataset
  • 103 unique unknown cultivars – some are likely seedlings. However, MORP took care to collect from grafted – not seedling trees – so many of these unique unknowns are also likely named historic cultivars not listed in the ARS dataset
  • 195 cultivars in total out of 489 MORP samples

Testing made possible by a 2015 Colorado USDA Specialty Crop Block Grant award to MORP
