Resumo: The objective of this work was to evaluate the relative contribution of variables related to fruit production and to seed morphophysiological characteristics to the genetic divergence in passion fruit (Passiflora edulis) progenies, aiming at selecting progenies potentially responsive to fertilization. Ten progenies were evaluated under conditions of low (50% of the recommended dose of fertilizers) and high soil fertility (dose 50% higher than the recommended one), regarding variable sets related to production and to the morphological and physiological characteristics of seeds. The association between these sets was determined by the canonical correlation analysis and by the nearest-neighbor clustering method. The nutritional environments interfered in the relative contribution of the variables to the genetic divergence of the progenies. The accelerated aging test of seeds – from the set of seed physiological quality – did not contribute significantly to the selection of genotypes responsive to soil fertilization. The most responsive progenies to the increased availability of nutrients were grouped according to the production variables that were evaluated under high soil fertility. Irrespectively of the evaluated environment, the set of production variables is the one that contributes more expressively to the identification of the genetic divergence of passion fruit progenies.

Dez progênies foram avaliadas em condições de baixa (50% da dose recomendada de fertilizantes) e alta fertilidade do solo (dose 50% superior à recomendada), quanto a conjuntos de variáveis de produção e de características morfológicas e fisiológicas das sementes. A associação entre esses conjuntos foi determinada pela análise de correlação canônica e pelo método de agrupamento do vizinho mais próximo. Os ambientes nutricionais interferiram na contribuição relativa das variáveis para a divergência genética das progênies. O teste de envelhecimento acelerado das sementes – do conjunto de variáveis de qualidade fisiológica – não contribuiu significativamente para a seleção de genótipos responsivos à adubação. As progênies mais responsivas ao aumento da disponibilidade de nutrientes foram agrupadas de acordo com as variáveis de produção avaliadas em condições de alta fertilidade do solo. Independentemente do ambiente avaliado, o conjunto de variáveis de produção é o que mais expressivamente contribui para a identificação da divergência genética de progênies de maracujazeiro-azedo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraRodrigues, Daniele LimaViana, Alexandre PioVieira, Henrique DuarteSantos, Eileen AzevedoSilva, Fernando Higino de Lima eSantos, Carlos Lacy2017-09-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/22317Pesquisa Agropecuaria Brasileira; v.52, n.8, ago. 2017; 607-614Pesquisa Agropecuária Brasileira; v.52, n.8, ago. 2017; 607-6141678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAengporhttps://seer.sct.embrapa.br/index.php/pab/article/view/22317/13809https://seer.sct.embrapa.br/index.php/pab/article/view/22317/13810https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/22317/14342https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/22317/14606Direitos autorais 2017 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2017-09-12T19:05:28Zoai:ojs.seer.sct.embrapa.br:article/22317Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2017-09-12T19:05:28Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
