Resumo: | The objective of this work was to evaluate the diversity between accessions of Cucurbita moschata from the Northeast of Brazil and preserved at the Universidade Federal Rural do Semi-Árido (UFERSA) in Mossoró-RN. The experiment was carried out in complete randomized blocks, with two replications and three plants per plot. The treatments consisted of 51 accessions of C. moschata Duch and a commercial cultivar of Cucurbita maximum Duch. After ripening, the fruits were harvested (one fruit per plant) and evaluated for morpho-agronomic descriptors. Univariate and multivariate variance analyzes were performed. From the dissimilarity matrices, accessions were hierarchically grouped by the UPGMA method. The relative contribution of quantitative characters to the divergence was also estimated. There was an effect of accessions (p <0.01 or p <0.05) for all characters in univariate analyzes, indicating that there is heterogeneity between the accessions evaluated. Considering the quantitative descriptors, the accessions formed eight groups and for the qualitative six groups. When considering the two sets of descriptors, the accessions were distributed in eight groups but presenting a greater distribution of accessions. The descriptors that most contributed to the discrimination of accessions were the firmness of the pulp and the length of the fruit. |

O experimento foi conduzido em blocos casualizados completos, com duas repetições e três plantas por parcela. Os tratamentos consistiram de 51 acessos de C. moschata Duch e uma cultivar comercial de Cucurbita máxima Duch. Após a maturação, os frutos foram colhidos (um fruto por planta) e avaliados para descritores morfoagronômicos. Foram efetuadas as análises de variâncias uni e multivariada. A partir das matrizes de dissimilaridade, agrupou-se hierarquicamente os acessos pelo método UPGMA. Também se estimou a contribuição relativa dos caracteres quantitativos para a divergência. Observou-se efeito de acessos (p<0,01 ou p<0,05) para todos os caracteres nas análises univariadas, indicando que existe heterogeneidade entre os acessos avaliados. Considerando os descritores quantitativos, os acessos formaram oito grupos e para os qualitativos seis grupos. Quando considerados os dois conjuntos de descritores os acessos foram distribuídos em oito grupos, porém apresentando uma maior distribuição dos acessos. Os descritores que mais contribuíram para a discriminação dos acessos foram a firmeza de polpa e comprimento do fruto.EDUFU2022-02-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/5419810.14393/BJ-v38n0a2022-54198Bioscience Journal ; Vol. 38 (2022): Continuous Publication; e38002Bioscience Journal ; v. 38 (2022): Continuous Publication; e380021981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/54198/33367Brazil; Contemporary Copyright (c) 2022 Rayanne Maria Paula Ribeiro, Carla Caroline Alves Pereira, Hamurábi Anizio Lins, Michele Barboza, Islan Diego Espindula de Carvalho, Glauber Henrique de Sousa Nunes, Lindomar Maria da Silveira, Aurélio Paes Barros Júniorhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessPaula Ribeiro, Rayanne MariaAlves Pereira, Carla CarolineHamurábi Anizio LinsBarboza, MicheleEspindula de Carvalho, Islan Diegode Sousa Nunes, Glauber Henriqueda Silveira, Lindomar MariaBarros Júnior, Aurélio Paes2022-02-16T21:57:09Zoai:ojs.www.seer.ufu.br:article/54198Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-02-16T21:57:09Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
