Little progeny from partial diallels were established in nine trials on coastal British Columbia, Canada. The trials were assessed for height, diameter, and crown form at age 12 years. An individual-genotype, linear mixed model with spatially correlated residuals was used to estimate the variance components and related genetic parameters. The majority of the estimated genetic variance for all traits was additive, and nonadditive genetic variance was predominantly due to dominance effects. Narrow-sense heritabilities for height and diameter at individual sites varied from 0.07 to 0.39, whereas for crown form, they were all less than 0.1. Dominance and epistasis ratios were, for the most part, lower than narrow-sense heritabilities. Common across-site additive and nonadditive genetic correlations were strongly positive and not significantly different from 1.0 for the majority of traits across sites within a series. Significant levels of additive genetic variance, coupled with insignificant to low nonadditive genetic variance for growth and crown form, would seem to be contrary to developing a clonal testing and deployment program. However, the lack of viable orchard seed and the faster delivery of genetic gain to reforestation, as well as more accurate forward selections based on additive genetic effects, makes this strategy viable for C. nootkatensis. <\/jats:p>","DOI":"10.1139\/cjfr-2014-0331","type":"journal-article","created":{"date-parts":[[2015,1,19]],"date-time":"2015-01-19T22:37:55Z","timestamp":1421707075000},"page":"689-697","update-policy":"https:\/\/doi.org\/10.1139\/csp-crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Multisite genetic parameter estimates from a <i>Callitropsis nootkatensis<\/i> diallel study with clonally replicated progeny"],"prefix":"10.1139","volume":"45","author":[{"given":"John H.","family":"Russell","sequence":"first","affiliation":[{"name":"British Columbia Ministry of Forests, Lands and Natural Resource Operations, Cowichan Lake Research Station, 7060 Forestry Road, Mesachie Lake, BC V0R 2N0, Canada."}]},{"given":"Jo\u00e3o","family":"Costa e Silva","sequence":"additional","affiliation":[{"name":"Centro de Estudos Florestais, Departamento dos Recursos Naturais, Ambiente e Territ\u00f3rio, Instituto Superior de Agronomia, Universidade de Lisboa, Tapada de Ajuda, 1349-017 Lisboa, Portugal."}]},{"given":"Brian S.","family":"Baltunis","sequence":"additional","affiliation":[{"name":"Weyerhaeuser, 32901 Weyerhaeuser Way S, Federal Way, WA 98001, USA."}]}],"member":"155","reference":[{"key":"refg1\/ref1","first-page":"147","volume":"37","author":"Adams W.T.","year":"1988","journal-title":"Silvae Genet."},{"key":"refg2\/ref2","doi-asserted-by":"publisher","DOI":"10.1139\/x02-070"},{"issue":"2","key":"refg3\/ref3","first-page":"231","volume":"39","author":"Balocchi C.E.","year":"1993","journal-title":"For.
