Infection of needles by Cronartium ribicola J. C. Fisch. ex Rabenh. depressed the level of root initiation by needle bundles obtained from Pinus monticola Dougl. seedlings. The depression was influenced by genetic background of the seedlings, an indication that resistance to the pathogen and rooting ability were not independent traits in certain half-sib families.

Leader lengths were compared for seedlings (i) from full-sib families and (ii) of mixed genetic background 12 times over their second growing season. We wished to examine whether the variation in genetically defined groups was equal to, or less than, that from a genetically diverse background. Aside from one time, there was no difference in within-group variation for full-sib seedlings and for those of mixed genetic background. When variation was not equal, it was one of the full-sib families that was the most variable. This indicates that the high within-population variation in Pseudotsuga menziesii reflects crossing between highly variable individuals and not a complex mixture of half-sib families.

Cultured tissues from Pseudotsuga menziesii (Mirb.) Franco were successfully inoculated with Cronartium ribicola J. C. Fisch. ex Rabenh. Typical intracellular haustoria were formed 60 days after inoculation. Invaded nonhost tissues were necrotic within 90 days, and dead within 120 days. Tissue cultures of either Pinus monticola Dougl. or P. menziesii had an attractant effect on nearby rust mycelium.

Artificial Inoculations

Tissue cultures of Pinus monticola Dougl. derived from stem cortex and leaf tissues were found susceptible to artificial inoculations with mycelium from the blister rust fungus (Cronartium ribicola Fisch. ex Rabenh.). Tissue cultures from leaf mesophyll grew slower and were colonized more rapidly by this fungus than those derived from stem cortex.

Low frequency of needle spots caused by the blister rust fungus (Cronartium ribicola J. C. Fisch. ex Rabenh.) in western white pine (Pinus monticola Dougl.) appears to be an expression of a horizontal resistance factor in secondary needles. Heritability averaged 37% for two sets of a 4 tester × 10 candidate mating system. We discuss the implications of these results with respect to developing varieties of western white pine resistant to blister rust.
