Resumo: This study was performed to introduce the allele Bush of commercial cultivars with a bush growth habit into Cucurbita moschata accessions and select the best crossings for production potential and standard fruit shape “Menina Brasileira” through general combining ability (GCA) and specific combining ability (SCA). To determine GCA and SCA, a partial diallel analysis was performed. The parental group (group I) consisted of two cultivars containing the dwarfism bush gene, and the second group (Group II), formed by five accessions of UFV Vegetable Germplasm Bank, with high production potential and fruit shape “Menina Brasileira”. We evaluated: productivity (PROD), fruit shape (FORM), growth rate until the 50th day after transplanting (CRESC), and length of the main stem on the 50th day (COMP). Significant differences were noticed for CRESC and COMP only between GCA of parents belonging to group I, in which Zapallo stood out. For PROD and FORM, diallel analysis proved to be efficient in studying GCA effects. Cultivar Piramoita (group I) and accessions BGH-4360 and BGH-5253 (group II) showed positive values for GCA, suggesting that these parents possess a higher frequency of favorable alleles for these two traits. Significance in SCA effects was also verified, highlighting the crossing Piramoita x BGH-4360, for PROD, indicating that this combination is the most promising for breeding purposes.

Para determinar a CGC e a CEC foi realizada análise dialélica parcial. O grupo parental (grupo I) foi formado por duas cultivares tipo “moita”, enquanto o segundo grupo (grupo II) por cinco acessos do Banco de Germoplasma de Hortaliças da UFV, com alto potencial produtivo e formato de fruto “menina brasileira”. Foram avaliadas a produtividade (PROD), o formato de fruto (FORM), a taxa de crescimento até os 50 dias (CRESC) e o comprimento da rama principal aos 50 dias (COMP). Para CRESC e COMP, houve diferenças significativas apenas entre a CGC dos genitores do grupo I, onde destacou-se a cultivar Zapallo. Para as características PROD e FORM a análise dialélica mostrou-se eficiente no estudo dos efeitos de CGC. A cultivar Piramoita (grupo I) e os acessos BGH-4360 e BGH-5253 (grupo II) apresentaram valores positivos para CGC, o que indica que esses genitores possuem maior frequência de alelos favoráveis para essas duas características. Também houve significância nos efeitos da CEC, com destaque para o cruzamento Piramoita x BGH-4360, para a característica PROD, sendo essa, a combinação mais promissora e mais indicada para seguir no programa de melhoramento de abóboras.Horticultura Brasileira2019-07-17T15:01:50Z2019-07-17T15:01:50Z2019-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf18069991http://dx.doi.org/10.1590/s0102-053620190105http://locus.ufv.br//handle/123456789/26253engv. 37, n. 01, p. 35- 39, jan./ mar. 2019Ferreira, Mariane G.Almeida, Gabriella Q. dePessoa, Herika P.Dariva, Françoise D.Dias, Felipe de O.Nick, Carlosinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFV2024-07-12T08:21:19Zoai:locus.ufv.br:123456789/26253Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452024-07-12T08:21:19LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false
