A total of ~6200 seedlings from 477 open-pollinated families from the full natural range were assessed in three separate experiments. Patterns of frost tolerance with race were not clear and consistent in all three experiments, although inland south-eastern Tasmanian and West Coast Tasmanian races were usually the more frost tolerant (T50 = \u20138.8\u00b0C, cf. overall mean of \u20138.3\u00b0C). Poor correlations between experiments also made clear identification of superior localities difficult. Winter-frost tolerance was a trait with considerable variation and also under strong additive genetic control. Estimated heritabilities of the relative electrical conductivity following a set freezing temperature and the calculated trait T50 were in the range of 0.27\u20130.71, with small standard errors. Predicted breeding values in all experiments indicated that the best families were tolerant of ~1.4\u00b0C colder temperatures than average. Seedlings appeared equally capable of rapid dehardening, when average T50 cold hardiness changed from \u201310.5 to \u20135.7\u00b0C during a 10-day period, or ~3\u20134\u00b0C per week. The issue of more thoroughly assessing the genetic basis of frost tolerance in E. globulus through field-testing is discussed.<\/jats:p>","DOI":"10.1071\/bt02061","type":"journal-article","created":{"date-parts":[[2006,9,14]],"date-time":"2006-09-14T18:28:52Z","timestamp":1158258532000},"page":"521-529","source":"Crossref","is-referenced-by-count":21,"title":["Genetic variation in frost resistance of Eucalyptus globulus ssp. globulus assessed by artificial freezing in winter"],"prefix":"10.1071","volume":"54","author":[{"given":"Wayne N.","family":"Tibbits","sequence":"first","affiliation":[{"name":"ACooperative Research Centre for Sustainable Production Forestry, School of Plant Science, University of Tasmania, GPO Box 252\u2013255 Hobart, Tas. 7001, Australia."},{"name":"BPresent address: Trees, Research and Environmental Solutions, 17 George Street, Ulverstone, Tas. 7315, Australia."},{"name":"FCorresponding author.
