This Research explores resistance to infection by Heterobasidion sop. in clones of Norway and Sitka spruce. Clones will be inoculated with H. animus, H. variorum or H. abietinum and the extent of pathogen growth and lesion development measured. Resistance of clones will be related to qualitative analysis of terrenes. QTL/AFLP maps will be used to determine molecular markers for resistance. Localising the accumulation of pathogenesis-related proteins and measuring rate of development of bark boundary and xylem barrier zones to infection will determine post-inflectional responses of clones. Resistance of wyvern to degradation by the pathogens will also be assessed. These data will be used to analyse inheritance of resistance, and to develop methods to predict inheritance of resistance based on experimentally determined markers.
