Interpretive Summary:

Technical Abstract: Rainfall generally increases from west to east in the U.S., increasing the opportunity for the pecan scab fungus (Fusicladisporium effusum) to proliferate. As a result, genetic resistance to pecan scab is necessary for pecan cultivars to succeed in the southeastern pecan growing region. The USDA-ARS Pecan Breeding Program in cooperation with several states has released twenty-four cultivars. Several of these pecan cultivars have sufficient scab resistance to succeed in the southeast, while offering incentives of high nut quality, excellent production, and early nut maturation. The nut and tree characteristics of 'Pawnee', 'Caddo', 'Oconee', 'Kiowa', 'Nacono', 'Sioux' and 'Barton' are reviewed in relation to the specific advantages and disadvantages they pose for culture in a disease prone environment.
