Description

The clearest patented record in this file, and the reason the rights field exists.

It is an open-pollinated seedling out of the American × Chinese hybrids growing in the Chestnut Hill orchards, three generations on from a 1953 North Carolina cross by Dr. Robert T. Dunstan between a healthy American chestnut and a composite tree carrying three USDA-released Chinese selections — ‘Kuling’, ‘Meiling’ and ‘Nanking’. Seedlings of that first cross were backcrossed to the parents, the second generation went into the orchard, and nuts from the largest and sweetest of those produced the third generation this cultivar came from.
