BACKGROUND INFORMATION AND COMMITTEE OBJECTIVES 



The First FAO World Consultation on Forest Genetics and Tree 

 Improvement, meeting in Stockholm in August, 1963, recognized the need 

 for coordination of the work of forest geneticists, pathologists, 

 entomologists, and physiologists in securing pest-resistant trees, and 

 recommended that the International Union of Forest Research Organizations 

 (IUFRO) establish a "Working Group on Parasite Resistance." In response 

 to this recommendation, at the 14th IUFRO Congress in Munich, September, 

 1967, IUFRO Section 22 (Study of Forest Plants--J. D. Matthews then 

 leader) and Section 24 (Forest Protection—A. Biraghi then leader) 

 established an Intersectional Working Group on Genetic Resistance to 

 Forest Diseases and Insects, appointing H. D. Gerhold of the U.S.A. as 

 Working Group Chairman. Then during late 1967 and 1968 Dr. Gerhold 

 established six disease and insect resistance committees within the 

 Working Group, appointing R. T. Bingham as Chairman of a Committee on 

 White Pine Blister Rust. 



Thus the Committee on (resistance to) White Pine Blister Rust became 

 functional about 1-1/2 years ago. Initially the Chairman, working with 

 a small group of volunteer committee members (P. Schtltt, Germany; R. F. 

 Patton, U.S.A.; B. F. S^egaard, Denmark) set about the business of 

 determining committee objectives, establishing a committee to attain these 

 objectives, and planning an organizational meeting. 



First, questions of pertinent committee objectives were explored. 

 One thorny question was paramount. Was securing lasting genetic resis- 

 tance to the white pine blister rust disease mainly a North American 

 problem, a North American and north European problem, or was it truly a 

 world-wide problem?
