Abstract
Seed from 125 seed sources were grown as greenhouse container stock. Seedlings were inoculated with either the North American or European strain of G. abietina. Inoculum was supplied as infected branches on a screen placed over trees. Inoculation techniques resulted in infection levels up to 100%. Results have produced susceptibility ratings for most conifers grown in North America. Variation in resistance by seed sources was found in Scots pine.
