RESEARCH SUMMARY 



A major problem facing those who wish to inoculate white pines with 

 Cronartium ribicola is the reliable production of teliospores. Also, a 

 better understanding of the nature of the various spore stages will add to 

 our ability to develop workable integrated rust management plans. 



The results reported in this paper will increase the reliability of 

 teliospore production in both whole plant and detached-leaf -culture of 

 Cronartium ribicola on Ribes plants, and add to our understanding of the 

 interaction between genes and the environment in the functioning of 

 epidemiological fitness traits.
