1. Resistance of the wild tomato Solanum habrochaites to Phytophthora infestans is governed by a major gene and polygenes
Abstract: This work aimed to study the inheritance of resistance to Phytophthora infestans in tomato plants, using the maximum likelihood estimation function. The susceptible cultivar Santa Clara (Solanum lycopersicum) was used as the female genitor and the P. infestans resistant S. habrochaites f. glabratum accession (BGH 6902) as the male genitor. F1 plant

2. Progresso temporal da queima das folhas em diferentes genótipos de cenoura
RESUMO A cultura da cenoura tem se expandido em diversos locais do Brasil e na região do Alto Vale do Itajaí, SC, grande parte da sua produção vem de agricultores familiares. Entretanto, a queima das folhas (Alternaria dauci) tem comprometido a produtividade. O objetivo do trabalho foi avaliar o progresso desta doença nos genótipos: Alvorada calibrada

3. Caracterização do progresso da queima das folhas em diferentes genótipos de cenoura
RESUMO A cultura da cenoura tem se intensificado devido ao consumo in natura e também pelo processamento industrial de conservas. Entretanto, a queima das folhas (Alternaria dauci) tem comprometido a produtividade. Como não se conhece o comportamento epidemiológico da doença nas condições de sul de Brasil, esse trabalho teve como objetivo analisar a ep

4. A diagramatic scale to quantify severity of antracnose in Rubus glaucus Benth
RESUMO: Mora de Castilla (Rubus glaucus Benth) é afetado por Colletotrichum acutatum, causando antracnose em órgãos diferentes da planta. Nos frutos geralmente é em pós-colheita, causando danos que geram perdas econômicas relacionadas com a qualidade das culturas. Ainda não existem para esse patossistema métodos padronizados para caracterizar quanti

5. Resistance and susceptibility of mandarins and their hybrids to Alternaria alternata
Caused by Alternaria alternata, Alternaria brown spot (ABS) is a major fungal disease of mandarins in Brazil, causing serious losses in commercial orchards of Ponkan tangerine (Citrus reticulata Blanco) and Murcott tangor [C. sinensis (L.) Osbeck × C. reticulata Blanco]. The response of 31 accessions/genotypes of mandarins and their hybrids to A. alternata,

7. Controle alternativo do míldio e da antracnose da videira com extrato aquoso de cinamomo (Melia azedarach L.) / Alternative control of downy mildew and anthracnose of grape aqueous extract of chinaberry (Melia azedarach L.)
The objective of this study was to evaluate different concentrations of aqueous extract of chinaberry (Melia azedarach L.) on the control of downy mildew (Plasmopara viticola) and anthracnose (Elsinoe ampelina) of grapevines cvs. Isabel and Cabernet Sauvignon. For all experiments the aqueous extract of chinaberry was prepared by addition of fruit with seeds

8. Behavior of rubber tree clones to the South American Leaf Blight (SALB) and potential impact of global climatic changes on the disease occurrence / Comportamento de clones de seringueira ao mal das folhas e potencial impacto das mudanças climáticas globais na ocorrência da doença
The unsuccessfulness of the natural rubber cultivation (Hevea spp.) on the cultivation areas in Brazil is due, mostly, to the occurrence of the rubber tree South American Leaf Blight (SALB), caused by the fungus Microcyclus ulei (P.Henn. v. Arx.). The strategies of the disease management are based on the genetic resistance of plants to the SALB, on the pheno

9. Mapeamento de locos de resistência quantitativa a Puccinia psidii Winter em uma progênie de irmãos completos de eucalipto / Mapping of quantitative resistance loci against Puccinia psidii Winter in a full-sib progeny of Eucalyptus
In Brazil, the eucalyptus rust, caused by Puccinia psidii Winter, stands out as the most important disease of eucalypts, mainly in southeastern Brazil. The use of resistant genotypes is the main control method, which makes the understanding of the genetic basis of resistance essential to the selection of resistant genotypes. In this study, an F1 progeny of 9

11. Genetic control of common bean resistance to white mold and backcross assisted by microsatellite markers / GENÃTICA DA RESISTÃNCIA DO FEIJOEIRO AO MOFO BRANCO E USO DO RETROCRUZAMENTO ASSISTIDO POR MARCADORES MICROSSATÃLITES.
The identification of sources of resistance to the white mold in common bean, and the study of its inheritance is primordial for the success of breeding programs aiming at resistant cultivars. The present research had the objectives: 1) to study the nature and the magnitude of genetic effects of resistance to white mold 2) use microsatellite (SSR) markers to
