Family variation in disease susceptibility in the species has not been investigated before. This is the first combined genetic analysis of susceptibility to <em>N. neomacrospora<\/em> and Christmas tree traits in Nordmann fir.<br \/>\n<strong>Aims<\/strong> Evaluate the genetic variation of susceptibility to <em>N. neomacrospora<\/em> and five Christmas tree traits in Nordmann fir.<br \/>\n<strong>Methods<\/strong> Five Christmas tree traits were measured on 2413 trees in a progeny test. Artificial inoculation was conducted on detached twigs of full-sib progenies with a <em>N. neomacrospora<\/em> isolate to assess the resistance\/susceptibility. Observed variation was partitioned into genetic and environmental causes to understand the heritable control of the traits.<br \/>\n<strong>Results<\/strong> Pronounced additive genetic variation was observed in susceptibility to <em>N. neomacrospora<\/em> and Christmas tree traits. Narrow-sense heritability for susceptibility to <em>N. neomacrospora<\/em> was 0.63. Significant differences between selfings and outcrossed trees were detected for all traits. Significant improvement for Christmas tree quality could be observed in the breeding process.<br \/>\n<strong>Conclusion<\/strong> Resistance to <em>N. neomacrospora<\/em> disease and other Christmas tree characteristics can be improved through recurrent selection.<\/p>\n<p><strong>Keywords<\/strong><br \/>\nPolymix mating; Spatial analysis; Narrow-sense heritability; Inbreeding<\/p>\n<div class='altmetric-embed' data-badge-type='donut' data-doi='10.1007\/s13595-021-01039-2'  style='float: right; ' ><\/div>\n<p><strong>Publication<\/strong><br \/>\nXu, J., Nielsen, U.B., Isik, F. et al.
