I am new to planting and would like to start with your recommendations.  I have been purchasing through e-bay but they don't list the specific type. Where can i find these Rootstocks and cultivars you recomend  for sale in the Dallas/Waco area?

Advances have been made in Texas walnut culture by Dr. Loy Shreve. He demonstrated that the native Texas Black Walnut, Juglans microcarpa, is a far superior rootstock for walnuts growing in high pH soils of Texas than the Eastern Black Walnut, Juglans nigra, or the California Black Walnut, Juglans hindsii. Growth of 10 feet or more the first year has been obtained with the Texas Black Walnut rootstock. Other rootstocks made little or no growth.

Cultivars

The need for an outstanding variety with “Walnut Blight” resistance has long been appreciated by Dr. Shreve. He traveled to Hungary and Romania in 1979 and collected several promising cultivars which were evaluated at the TAMU Center at Uvalde. The best cultivars to date are Reda, Geoagiu 86, Orastie, Germisara, and Geoagiu 3 X 4 X 453. Under Texas conditions, these cultivars appear to be superior to the standard commercial varieties Payne, Eureka, Hartley, and Broadview.
