I am searching for a 1919 publication from the North Carolina Agricultural Experiment Station:
Author: DETJEN, L. R.
Title: Some F1 Hybrids of Vitis Rotundifolia With Related Species and Genera
Journal title: North Carolina Agricultural Experiment Station, Technical Bulletin No. 18, Year: 1919
This is in reference to Detjen's intergeneric hybrid grapevine NORTH CAROLINA 6- 15, which is a female-flowered parent in the deep genetic background of a recent French/German hybrid grapevine "Vidoc".
I have an avocational interest in grapevine genetics, and in winegrowing. This is perhaps the most arcane request for information I have ever made.
