Abstract
The introduction of scab (Venturia pirina) resistant pear varieties will increase the economic return of fruit growers and benefit food safety and the environment through a reduction of fungicide use. Seedling progenies of 11 families derived from the controlled cross-pollination of 10 pear varieties: Ya Li, Hood, Buttira Precoce Morettini (BPM), Guyot, Howell, Corella, Rogue Red, Comice, Williams' Bon Chretien (WBC) and Eldorado, were examined for their response to scab infection in a diseased orchard during the 2004/05 and 2005/06 cropping seasons. The infection was rated by a 9-point scale on diseased leaves of seedling trees with nine being most severe infection. The weather conditions i..
