Title: Evaluation of Foreign Peach and Nectarine Introductions in the U.S. for Resistance of Leaf Curl [Taphrina deformans (Berk.) Tul.]
Author: R. Scorza
Abstract:
Sixty-six U.S. peach and nectarine introductions and six commercial cultivars were visually evaluated for leaf curl infection in the spring in each of 3 years.
Most genotypes were moderately susceptible.
Twelve plant introductions
were highly resistant, some showing no visible symptoms of infection.
These genotypes appear to be valuable sources of resistance to leaf curl currently available to peach and nectarine breeders.
