Stability of TSWV General Field Resistance in the ’Georgia Green’ Peanut Cultivar

W. D. Branch and A. K. Culbreath

May 2015

Research

There are mainly two types of host-plant disease resistance: general or horizontal, and specific or vertical. In most cases, general resistance may provide a lower level of control, but is usually more desirable for long-term stability. The objective of this 13-year study was to determine the stability of the general disease resistance to tomato spotted wilt (TSW), caused by Tomato spotted wilt virus (TSWV), found in the peanut cultivar ’Georgia Green’, as indicated by comparisons with the highly susceptible ’Florunner’ cultivar.
