1. Early selection for resistance to Heterobasidion parviporum in Norway spruce is not likely to adversely affect growth and wood quality traits in late-age performance

Abstract:
... Infections with Heterobasidion parviporum devalue the Norway spruce timber as the decayed wood does not meet the necessary quality requirements for sawing. To evaluate the incorporation of disease resistance in the Norway spruce breeding strategy, an inoculation experiment with H. parviporum on 2-year-old progenies of 466 open-pollinated families was conducted under greenhouse (nursery) conditions ...

Abstract:
... In forest breeding, growth has been used as the main selection trait in Norway spruce (Picea abies L. Karst.), whereas wood properties or resistance to pathogens have been taken as secondary traits. We aimed to investigate, in laboratory conditions, the rate of wood decay caused by Heterobasidion parviporum (Fr.) Niemela & Korhonen (strains 5 and 7) in 20 Norway spruce clones. We also studied if, ...

Abstract:
... Heterobasidion annosum (FR.) BREF. sensu lato causes severe economic damage in stands of Norway spruce (Picea abies [L.] Karst). The primary damage is the deterioration of timber by decay. Secondary damage can be attributed to higher risks of windthrow and stem breakage, growth reduction of infected trees as well as higher machining and handling costs for decayed stems during grading and processin ...
