However, relationships between environmental variables and genotype by environment interaction are complex.<\/em><\/p>\n<p class=\"a-plus-plus\" style=\"text-align: justify\">Current radiata pine breeding and deployment in Australia is based largely on the plantation inventory zones rather than on biological patterns of genotype by environment interaction (G\u2009\u00d7\u2009E), and consequently cannot deliver optimal genetic gains across the whole plantation estate. This study examined patterns of G\u2009\u00d7\u2009E to facilitate deployment of genetic stock to particular environments. We used 20 genetically well-connected trials across southern Australia to obtain estimates of genetic correlations between performances at different trial sites. Extended factor analyses (XFA) were used to estimate G\u2009\u00d7\u2009E variance and produce a matrix of site-site genetic correlations. The patterns among these correlations were examined using a heat map and hierarchical clustering. The XFA captured a large proportion of both additive and non-additive G\u2009\u00d7\u2009E. Significant G\u2009\u00d7\u2009E for diameter growth can be expected between Tasmania and Mainland, and within Tasmania itself. The study also confirmed presence of G\u2009\u00d7\u2009E between Murray Valley region in <a class=\"reference-link webtrekk-track\" href=\"http:\/\/link.springer.com\/search?dc.title=New+South+Wales&amp;facet-content-type=ReferenceWorkEntry&amp;sortOrder=relevance\">New South Wales<\/a> and the rest of southern Australia. The G\u2009\u00d7\u2009E interaction at transcontinental scale can be correlated to the climate variables, primarily rainfall and temperature; however, the drivers of G\u2009\u00d7\u2009E may also be related to smaller scale environmental variation (i.e. soil and terrain variation).<\/p>\n<p class=\"a-plus-plus\" style=\"text-align: justify\"><a href=\"http:\/\/link.springer.com\/article\/10.1007\/s13595-014-0437-6http:\/\/\" target=\"_blank\">Link to the full paper.<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Milos IVKOVIC, Washington GAPARE, Huixiao YANG, Gregory DUTKOWSKI, Peter BUXTON, Harry WU CSIRO Agriculture Flagship, GPO Box 1600, Canberra, ACT, 2601, Australi; College of Forestry, Guangdong Academy of Forestry, Guangzhou, 510520, China; PlantPlan Genetics, Private Bag 55, Hobart, TAS, 7001, Australia; Southern Tree Breeding Association, PO Box 1811, Mount Gambier, SA, 5290, Australia Key message: [&hellip;]<\/p>\n","protected":false},"author":35,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[14,15],"tags":[],"class_list":["post-1047","post","type-post","status-publish","format-standard","hentry","category-article-type","category-research-paper","cat-14-id","cat-15-id"],"_links":{"self":[{"href":"https:\/\/ist.blogs.inrae.fr\/afs\/wp-json\/wp\/v2\/posts\/1047","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ist.blogs.inrae.fr\/afs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ist.blogs.inrae.fr\/afs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ist.blogs.inrae.fr\/afs\/wp-json\/wp\/v2\/users\/35"}],"replies":[{"embeddable":true,"href":"https:\/\/ist.blogs.inrae.fr\/afs\/wp-json\/wp\/v2\/comments?post=1047"}],"version-history":[{"count":0,"href":"https:\/\/ist.blogs.inrae.fr\/afs\/wp-json\/wp\/v2\/posts\/1047\/revisions"}],"wp:attachment":[{"href":"https:\/\/ist.blogs.inrae.fr\/afs\/wp-json\/wp\/v2\/media?parent=1047"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ist.blogs.inrae.fr\/afs\/wp-json\/wp\/v2\/categories?post=1047"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ist.blogs.inrae.fr\/afs\/wp-json\/wp\/v2\/tags?post=1047"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
