Resumo: This study investigated the genetic variability in progenies of Eucalyptus dunnii Maiden for resistance against rust (Puccinia psidii). Field experiments were installed in two regions with differentsoil-climatic conditions. Open-pollinated progenies were established in arandomized complete block design. Sixty and 48 progenies were evaluated underfield conditions at two sites, respectively, with six replications and eight trees per plot. In another experiment in a controlled environment, 53 progenies were evaluated in randomized blocks with six replications and nine plants perplot. The following traits were evaluated: plant height, severity of pestattack and the most susceptible stage to the leaf disease. The genetic variability for rust resistance in the E. dunnii population under studywas high, with a genetic coefficient of variation of 36.07%; 7% of thee valuated progenies were rust-resistant. It indicates a high potential for selection and breeding of the species.

Experimentos de campo foram instalados em duas regiões edafoclimáticas.Progênies de polinização aberta foram estabelecidas em um delineamento emblocos casualizados. Em condições de campo foram avaliadas 60 e 48 progênies emdois locais, com seis repetições e oito plantas por parcela. Instalou-se tambémum experimento em ambiente controlado, com 53 progênies, em blocoscasualizados, com seis repetições e nove plantas por parcela. Foram avaliadas altura da planta e a severidade de ataque que determinam a fase mais suscetível à doença foliar. A população de E. dunnii estudada apresentou altavariabilidade genética para resistência à ferrugem, com coeficiente de variaçãogenética de 36, 07% e 70% das progênies avaliadas foram imunes a ferrugem. Istoindica alto potencial para seleção e melhoramento da espécie.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Universidade Estadual Paulista Júlio de Mesquita FilhoUniversidade Federal de TocantinsUniversidade de São Paulo Escola Superior de Agricultura Luiz de QueirozUniversidade Estadual Paulista Júlio de Mesquita FilhoCrop Breeding and Applied BiotechnologyUniversidade Estadual Paulista (Unesp)Universidade Federal de TocantinsUniversidade de São Paulo (USP)Pinto, Cleber Da Silva [UNESP]Costa, Rodolfo Manoel Lemes Da [UNESP]Moraes, Cristiano Bueno DePieri, Cristiane De [UNESP]Tambarussi, Evandro VagnerFurtado, Edson Luiz [UNESP]Mori, Edson Seizo [UNESP]2015-02-02T12:39:32Z2015-02-02T12:39:32Z2014-10-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/conferenceObject187-193application/pdfhttp://dx.doi.org/10.1590/1984-70332014v14n3a28Crop Breeding and Applied Biotechnology.
