Resumo: | Anthracnose is presented as one of the most relevant phytosanitary problems to the soybean in the Cerrado. The genetic improvement contributes to the increase of productivity in the state through its capacity to resist to adverse factors, such as the diseases. The most used commercial soy cultivars is resistant to diseases, although, with regard to anthracnose, there is difficulty in obtaining resistant cultivars, due to the great variability of the pathogenic agent. Based on that, the aim was to evaluate the trees damping off in pre and pos emergency, the occurrence and the severity in 6 soy cultivars (Agroeste 3820 IPRO, TMG 1188 RR, TMG 132 RR, M-SOY 8866 conventional, TMG 1179 RR and M-SOY 9144 RR), inoculated with Colletotrichum isolates, collected by soy tress which present the symptoms. The assessments happened between the Vc and V3 phenological stages. The damping off was evaluated on the seventh day after the sowing. The first incidence and severity evaluation happened seven days after the sowing and the following assessments were carried out every four day, totaling five evaluations, Severity was evaluated according to Anthracnose diagrammatic scale. The incidence and severity data were undergone to the Area Under Progress Curve Disease (AUDPC) calculation, in order to observe the advance of the disease through time. It was observed significant interaction between isolated and cultivars. The inoculated plants presented anthracnose symptoms; however, the witnesses did not present the disease symptoms, thus demonstrating the pathogenicity of the twenty-seven tested isolates. The M-SOY 8866 conventional, TMG 1179 RR and M-SOY 9144 RR cultivars statistically differ from the Agroeste 3820 IPRO, TMG 1188 RR and TMG 132 RR cultivars presenting high percentage of AUDPC damping off. The IT-4, IT-6, LU-3, NU-5, PN-1, QU-2, SO-11, VE-5 and VR-1 isolates presented higher aggressiveness. |

O melhoramento genético contribui para o aumento da produtividade do estado por meio de resistência a fatores adversos como, por exemplo, as doenças. As cultivares comerciais de soja mais utilizadas possui resistência a doenças, no entanto, em relação à antracnose há dificuldade na obtenção de cultivares resistentes, devido ampla variabilidade do patógeno. Diante disso, objetivou-se avaliar o tombamento de plantas em pré e pós emergência, a incidência e severidade, em 6 cultivares de soja (Agroeste 3820 IPRO, TMG 1188 RR, TMG 132 RR, M-SOY 8866 convencional, TMG 1179 RR e M-SOY 9144 RR), inoculadas com 27 isolados de Colletotrichum, obtidos de plantas de soja com sintomas. As avaliações ocorreram entre os estádios fenológicos Vc e V3. O tombamento foi avaliado no sétimo dia após a semeadura. A primeira avaliação da incidência e da severidade ocorreu 7 dias após a semeadura e as demais avaliações foram realizadas com intervalo de 4 dias, totalizando 5 avaliações. A severidade foi avaliada de acordo com escala diagramática de antracnose. Os dados de incidência e severidade foram submetidos à fórmula da Área Abaixo da Curva de Progresso da Doença (AACPD) a fim de observar o avanço dos sintomas ao longo do tempo. Foi observada interação significativa entre os isolados e as cultivares. As plantas inoculadas apresentaram sintomas de antracnose, em contrapartida, as testemunhas não apresentaram sintomas da doença, demonstrando, desta maneira, a patogenicidade dos 27 isolados testados. As cultivares MSOY 8866 convencional, TMG 1179 RR e M-SOY 9144 RR diferiram-se estatisticamente das cultivares Agroeste 3820 IPRO, TMG 1188 RR e TMG 132 RR, apresentando elevada porcentagem de tombamento e AACPD. Os isolados IT-4, IT-6, LU-3, NU-5, PN-1, QU-2, SO-11, VE-5 e VR-1 apresentaram maior agressividade.Universidade Federal de Mato GrossoBrasilInstituto de Ciências Agrárias e Ambientais (ICAA) – SinopUFMT CUS - SinopAgronomia - CUSMoraes, Sylvia Raquel Gomeshttp://lattes.cnpq.br/4795171079324331Bonaldo, Solange Mariahttp://lattes.cnpq.br/3703629752105309Moraes, Sylvia Raquel Gomeshttp://lattes.cnpq.br/4795171079324331Bonaldo, Solange Mariahttp://lattes.cnpq.br/3703629752105309Barcelos, Quélen de Limahttp://lattes.cnpq.br/5279571519467033SILVA, Jaqueline Bezerra da2019-03-28T13:43:59Z2016-04-082019-03-28T13:43:59Z2016-03-02info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/datasetSILVA, Jaqueline Bezerra da.
