Abstract

Western white pine trees resulting from crosses of parents selected for phenotypic resistance to Cronartium ribicola J. C. Fisch. ex Rabenh., the white pine blister rust, were inspected for rust infection after 11 to 15 years in two field plots. When compared to controls and to natural reproduction, the progenies of crosses involving trees that exhibited general combining ability for resistance transmission in nursery tests were much less heavily infected (20 percent on the average, as opposed to 58 and 71 percent for controls and natural reproduction, respectively).
