Genetic Disease Resistance in Wild Apple
USDA and Cornell University researchers identified genes responsible for resistance to apple scab, cedar apple rust and fire blight in wild apple collections from Turkey and southern Russia. Analysis of the collected populations revealed localized regions of genetic diversity and high overall levels of disease resistance. An understanding of disease resistance and genetic diversity in germplasm collections may increase use of these valuable genetic resources in breeding programs.
The findings were featured on the cover of the May 2008 issue of the Journal of the American Society for Horticultural Science.
