Resumo: | The objective of this work was to determine how the number of commercial fruit per plant (CFrP) is related to 16 morphological and agronomical traits in papaya (Carica papaya L.). The experiment was carried out in the 2008/2009-crop season, using an augmented randomized block design. Nineteen non-common (germplasm accessions) and three common genotypes (varieties and hybrids) were evaluated with ten repetitions. Correlations between CFrP and morpho-agronomic traits were outspread in direct and indirect effects. High variability was found for the evaluated traits. The estimates of genetic correlations were higher than phenotypic correlations for all characters. CFrP was positively and significantly correlated with number of fruits per axil (NFAx) and negatively with the internal diameter of the cavity of the fruit, pulp thickness, fruit weight, fruit length (FrL) and fruit diameter. However, path analysis showed that, among this traits, NFAx and FrL have more direct effect on CFrP. Furthermore, plant height, number of flowers per peduncle and leaf width are more easily measured and are expressed before fruit production, making them more suitable for indirect selection in breeding programs of this crop. |

O experimento foi realizado no ano agrícola de 2008/2009, utilizando o delineamento experimental de blocos aumentados. Foram avaliados 19 genótipos não comuns (acessos de germoplasma) e 3 comuns (variedades e híbridos), em 10 repetições. As correlações entre NFr e as características morfoagronômicas do mamoeiro foram desdobradas em efeitos diretos e indiretos. Observou-se alta variabilidade nas características avaliadas. As estimativas das correlações genotípicas foram maiores do que as fenotípicas, para todas as características. O NFr foi positivo e significativamente correlacionado com número de frutos por axila (NFrAx); e negativamente com diâmetro da cavidade do fruto, espessura da polpa, peso, comprimento (CFr) e diâmetro do fruto. Entretanto, a análise de trilha demonstrou que, entre essas características, NFrAx e CFr possuem maior efeito direto sobre NFr. Além disso, as características altura da planta, número de flores por pedúnculo e largura da folha são de mais fácil mensuração e manifestam-se antes da produção de frutos, o que as torna mais indicadas para a seleção indireta em programas de melhoramento genético dessa cultura.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCNPq e FapesbOliveira, Eder JorgeLima, Diego Souza deLucena, Rangel SalesMotta, Tiago Borges NunesDantas, Jorge Luiz Loyola2011-01-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/8145Pesquisa Agropecuaria Brasileira; v.45, n.8, ago. 2010; 855-862Pesquisa Agropecuária Brasileira; v.45, n.8, ago. 2010; 855-8621678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/8145/6082https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/8145/3777info:eu-repo/semantics/openAccess2014-11-07T19:53:04Zoai:ojs.seer.sct.embrapa.br:article/8145Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-11-07T19:53:04Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
