Fifteen out of 96 half-sib families were selected as less susceptible. This experiment is an important first step for creating a resistance breeding program.<\/p>\n<p align=\"justify\"><strong>Context<\/strong> Pine wilt disease is caused by the pinewood nematode (<em>Bursaphelenchus xylophilus<\/em> (Steiner et Buhren) Nickle), a quarantine pest, and is a concern to maritime pine (<em>Pinus pinaster<\/em>) in Portugal due to its economic, environmental, and social impacts. This disease is regarded as a major threat to European forests.<br \/>\n<strong>Aims<\/strong> This paper aimed to evaluate the genetic variation in maritime pine families that were inoculated with pinewood nematode, identify the most resistant families, and establish the guidelines for a resistance improvement program.<br \/>\n<strong>Methods<\/strong> Two-year-old half-sib progenies obtained from 96 plus trees were inoculated. The plants were monitored for survival on four different dates. The statistical analysis followed the mixed model theory.<br \/>\n<strong>Results<\/strong> Genetic variability of the susceptibility to pine wilt disease was observed. At 157 days after inoculation, the 15 highest genetic ranking families out of 96 were selected, having a predicted survival mean of 15.6% instead of 11.0% on average for the all 96 families.<br \/>\n<strong>Conclusion<\/strong> This study allows for the implementation of an improvement program to help control pine wilt disease.<\/p>\n<p><strong>Keywords<\/strong><br \/>\nGenetic variability, Mixed models, <em>Bursaphelenchus xylophilus<\/em>, Progeny test, Tree improvement, Resistance<\/p>\n<div class='altmetric-embed' data-badge-type='donut' data-doi='10.1007\/s13595-018-0759-x'  style='float: right; ' ><\/div>\n<p><strong>Publication<\/strong><br \/>\nCarrasquinho, I., Lisboa, A., In\u00e1cio, M.L. et al.
