Resumo: | The objective of this work was to select accessions resistant to early blight (Alternaria tomatophila) through cluster analysis of the disease progress curves in tomato (Solanum lycopersicum). One hundred and thirty‑four tomato accessions from the Banco de Germoplasma de Hortaliças of Universidade Federal de Viçosa (BGH‑UFV) were evaluated in a randomized complete block design, as well as the susceptible controls 'Débora' and 'Santa Clara'. The plants were inoculated with a mixture of spores from different Alternaria spp. isolates and evaluated regularly regarding disease severity every three days after inoculation, totalizing six evaluations. The logistic model was adjusted to data on early blight severity, and the estimates obtained for final disease incidence (B1) and rate of disease progression (B3) were subjected to multivariate analysis of variance (Manova). The means of these estimates, for each access, were subjected to cluster analysis. Twenty‑four distinct groups were formed based on disease‑progress curve clusters, which allowed the identification of the BGH‑2143, BGH‑2235, BGH‑2270, and BGH‑2118 accessions as potential sources of resistance to early blight. |

Foram avaliados 134 acessos de tomateiro do Banco de Germoplasma de Hortaliças da Universidade Federal de Viçosa (BGH‑UFV), no delineamento de blocos ao acaso, além das testemunhas suscetíveis 'Débora' e 'Santa Clara'. As plantas foram inoculadas com uma mistura de conídios de diferentes isolados de Alternaria spp. e avaliadas regularmente quanto à severidade da doença a cada três dias após a inoculação, no total de seis avaliações. Ajustou-se o modelo logístico aos dados de severidade da pinta‑preta, e as estimativas obtidas para a incidência final da doença (B1) e a taxa de progresso da doença (B3) foram submetidas à análise de variância multivariada (Manova). As médias dessas estimativas, para cada acesso, foram submetidas à análise de agrupamento. Foram formados 24 grupos distintos com base no agrupamento das curvas de progresso da doença, o que possibilitou identificar os acessos BGH‑2143, BGH‑2235, BGH‑2270 e BGH‑2118 de tomateiro como potenciais fontes de resistência à pinta‑preta.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFapemigCNPqCapesLaurindo, Bruno SoaresLaurindo, Renata Dias FreitasAzevedo, Alcinei MisticoNick, CarlosSilva, Derly José Henriques daMizubuti, Eduardo Seiti Gomide2015-02-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/19855Pesquisa Agropecuaria Brasileira; v.50, n.2, fev. 2015; 106-114Pesquisa Agropecuária Brasileira; v.50, n.2, fev. 2015; 106-1141678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/19855/12858https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/19855/12079info:eu-repo/semantics/openAccess2015-02-27T12:14:49Zoai:ojs.seer.sct.embrapa.br:article/19855Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2015-02-27T12:14:49Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
