Resumo: | The aim of this work was to perform botanical identification and to estimate genetic diversity in two sequential inbred generations (progenies S1 and S2) of melon accessions from traditional agriculture in the state of Maranhão, in order to generate useful information for commercial melon breeding. Two field experiments were carried out in a completely randomized block, using four replicates of 15 accessions from a first selfing cycle in 2013, and three replicates of 25 subaccessions (generation S2) in 2014. Flower and fruit descriptors were measured to obtain quantitative and qualitative data, in addition to a systematized photographic documentation of fruit for visually comparing the progenies S1 and S2. Distance matrices for quantitative and qualitative data were obtained and used to perform a joint analysis and UPGMA method. Large genetic diversity was found in the accessions analysed, since the presence of melon progenies was observed in the Cucumis melo ssp. agrestis, with its botanical varieties momordica and conomom, and of the Cucumis melo ssp. melo, with the botanical varieties cantalupensis and chandalak. Divergence analysis showed the formation of three groups in generation S1 and four groups in S2. However, the groups were not separated either by subspecies or by botanical variety. Thus, in addition to the large genetic diversity among and within melon accessions from family farming in the state of Maranhão, the progenies presented a large introgression of traits of the different subspecies and their botanical varieties due to the reproductive system and seed management of these species. |

Foram conduzidos dois experimentos de campo em blocos casualizados completos, com quatro repetições e 15 acessos em 2013 e, três repetições e 25 subacessos em 2014. Para avaliação dos acessos foram aplicados descritores quantitativos e qualitativos de flor e fruto, além de uma documentação fotográfica sistematizada dos frutos com análise visual, comparando os frutos das gerações S1 e S2. Foram obtidas as matrizes de distância nos dois tipos de descritores e se fez a análise conjunta e em seguida realizou-se o agrupamento pelo método UPGMA. Verificou-se que nos acessos analisados, existe uma grande diversidade genética, pois foram encontradas progênies de melão da subespécie agrestis e suas variedades botânicas momordica e conomom e da subespécie melo com as variedades botânicas cantalupensis e chandalak. A análise de divergência na geração S1 mostrou a formação de três grupos e na geração S2 foram formados quatro agrupamentos, entretanto os grupos não foram formados nem por subespécie nem por variedade botânica. Assim, além de se ter encontrado uma grande diversidade genética entre e dentro dos acessos de melão da agricultura familiar maranhense, é provável que tenha ocorrido grande introgressão de alelos das subespécies e das diferentes variedades botânicas na área dos agricultores devido ao sistema reprodutivo da espécie a ao manejo de sementes.Universidade Federal Rural do Semi-Árido2017-03-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/558810.1590/1983-21252017v30n308rcREVISTA CAATINGA; Vol. 30 No. 3 (2017); 602-613Revista Caatinga; v. 30 n. 3 (2017); 602-6131983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/5588/pdfMacêdo, Simone de SouzaQueiróz, Manoel Abilio deAquino, Iana Priscila Freitas deOliveira, Ronaldo Simão deLima Neto, Izaias da Silvainfo:eu-repo/semantics/openAccess2023-07-20T11:12:54Zoai:ojs.periodicos.ufersa.edu.br:article/5588Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:23.165042Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
