Resumo: | This work had the objective to evaluate watermelon genotypes resistance to alternaria leaf blight (Alternaria cucumerina) in two environments (years) in order to identify contrasting and consistent parents as well as to get information related to environmental and genetic effects to support strategies to be followed in watermelon breeding programs. Two experiments were carried out in the Experimental Field of the Department of Technology and Social Sciences (DTCS) at the Campus III of the University of the State of Bahia (UNEB), Juazeiro-BA in the years of 2006 and 2007. In both experiments, the treatments consisted of 14 watermelon genotypes comprising 12 progenies and two checks (Sugar Baby and Charleston Gray cultivars). The seedlings were produced in a green house and were transplanted to the field with previous records of high incidence and severity of the disease. The experimental design was in randomized blocks, with three replications. The plot had five plants spaced 3.0 m between lines and 0.8 m between plants. The irrigation was supplied in furrows. The cultural practices were those normally used for watermelon, but without fungicides. The plants were evaluated 75 days after transplanting using a grading records ranging from: one plants more resistant; to five plants more susceptible. It was found G x A interaction in the evaluation of watermelon genotypes for alternaria leaf blight in the Submiddle São Francisco River Basin with predominance of the complex part of the interaction and that the major part of the phenotypic variance was accounted for genetic factors (74.5%). It was identified a consistent source for resistance to alternaria leaf light represented by the progeny P5 (91-0043) and as a contrasting susceptible parent the Sugar Baby variety was selected. Both, demonstrate a high potential for breeding purposes, and can be used in studies of inheritance of resistance of alternaria leaf blight |

Realizou-se dois experimentos no Campo Experimental do Departamento de Tecnologia e Ciências Sociais (DTCS), localizado no Campus III da Universidade do Estado da Bahia (UNEB), Juazeiro-BA, nos anos de 2006 e 2007. Em ambos os ensaios, os tratamentos consistiram de 14 genótipos de melancia, representados por 12 progênies e duas testemunhas (variedades Sugar Baby e Charleston Gray). As mudas foram produzidas em casa de vegetação e transplantadas para áreas com histórico de alta incidência e severidade da doença. O delineamento experimental foi em blocos ao acaso, com três repetições, sendo a unidade experimental constituída por cinco plantas. O espaçamento foi de 3,0 m entre fileiras e 0,8 m entre plantas e a irrigação por infiltração por sulco, empregando-se os tratos culturais normalmente utilizados para a cultura, sem uso de fungicidas. Avaliou-se as plantas aos 75 dias após o transplantio, sendo atribuída uma escala de notas variando de: um planta mais resistente; a cinco planta mais suscetível. Verificou-se que houve interação G x A na avaliação de genótipos de melancia quanto à resistência à alternariose no Submédio São Francisco com predomínio da parte complexa e que a maior parte da variância fenotípica observada foi explicada por fatores genéticos (74,5 %). Identificou-se uma fonte consistente para resistência à alternariose representada pela progênie P5 (91-0043) e como parental contrastante (suscetível) selecionou-se a variedade Sugar Baby. Ambas, demonstraram um alto potencial para fins de melhoramento, podendo ser utilizadas em estudo de herança da resistência a alternáriaConselho Nacional de Desenvolvimento Científico e Tecnológicoapplication/pdfhttp://repositorio.ufersa.edu.br/retrieve/338/IzaiasSLN_DISSRT.pdf.jpgporUniversidade Federal Rural do Semi-ÁridoPrograma de Pós-Graduação em FitotecniaUFERSABRCentro de Ciências Agrárias - CCACC-BY-SAinfo:eu-repo/semantics/openAccessCitrullus lanatuswatermelon breedingAlternaria cucumerinaCitrullus lanatusmelhoramento de melanciaAlternaria cucumerinaCNPQ::CIENCIAS AGRARIAS::AGRONOMIAInteração genótipo x ambiente na reação de progênies de melancia à alternariose no Submédio São FranciscoGenotype-environment interaction in the reaction of watermelon progenies to alternaria leaf blight in the Submiddle São Francisco regioninfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisreponame:Biblioteca Digital de Teses e Dissertações da UFERSAinstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSATEXTIzaiasSLN_DISSRT.pdf.txtIzaiasSLN_DISSRT.pdf.txtExtracted texttext/plain135090https://repositorio.ufersa.edu.br//bitstream/tede/53/3/IzaiasSLN_DISSRT.pdf.txtf1fbe96bfddf08089bfc0302fee9d663MD53ORIGINALIzaiasSLN_DISSRT.pdfapplication/pdf855580https://repositorio.ufersa.edu.br//bitstream/tede/53/1/IzaiasSLN_DISSRT.pdf74d0222de91251c309dd5924d2d636eeMD51THUMBNAILIzaiasSLN_DISSRT.pdf.jpgIzaiasSLN_DISSRT.pdf.jpgGenerated Thumbnailimage/jpeg3258https://repositorio.ufersa.edu.br//bitstream/tede/53/2/IzaiasSLN_DISSRT.pdf.jpgf073269236c24e97638ae25eb64489d4MD52tede/532022-07-05 16:45:16.355oai:repositorio.ufersa.edu.br:tede/53Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufersa.edu.br/PUBhttp://bdtd.ufersa.edu.br/oai/requestdirecaosisbi@ufersa.edu.br|| direcaosisbi@ufersa.edu.bropendoar:2022-07-05T19:45:16Biblioteca Digital de Teses e Dissertações da UFERSA - Universidade Federal Rural do Semi-Árido (UFERSA)false |
