We studied genetic parameters including genotype by environment interaction (G × E) of resistance to P. psidii rust in Eucalyptus grandis at nine sites in São Paulo State. Open-pollinated progeny from ten ‘provenances' were established in a randomized complete block design; at individual sites there were from 134 to 160 progenies, from four to eight blocks, and five to six trees per plot. Significant provenance and progeny(provenance) differences were detected, as was G × E involving progeny(provenance). However, the G × E involved little if any rank changes, indicating that selection can be done efficiently at a single site, if the disease level is sufficient. The estimated coefficient of genetic variation among the progeny within provenances $$ \left( {{{{\widehat{\mathrm{CV}}}}_{\mathrm{g}}}} \right) $$ was high and variable among the sites (ranging from 11% to 36.7%), demonstrating different expression of genetic variability among the sites. The estimated heritability at the individual-tree level $$ \left( {{{\widehat{h}}^2}} \right) $$ and within a plot $$ \left( {\widehat{h}_{\mathrm{w}}^2} \right) $$ ranged from low to intermediate (ranging from 0.04 to 0.46) and was high at the progeny-mean level $$ \left( {\widehat{h}_{\mathrm{f}}^2} \right) $$ (ranging from 0.30 to 0.86). Our study shows good prospects of controlling this disease by selection among and within progenies in a single site.
