| English abstract | The objective of this work was to assess the genetic similarity of the following citrus fresh fruit market seedless cultivars: Lane Late, Navelate, Navelina and Salustiana sweet oranges (Citrus sinensis (L.) Osbeck), Clemenules and Marisol mandarins (C. reticulata Blanco) and Okitsu satsuma mandarin (C. unshiu Marcovitch), and the hybrids Nova [C. clementina x (C. paradisi x C. tangerina)] and Ortanique (tangor probably derived from C. sinensis (L.) Osbeck x C. reticulata Blanco), utilizing isoenzymatic markers. Electrophoresis analysis of proteins extracted from leaf tissues was utilized to detect polymorphisms at ten isoenzymatic systems. Out of 30 alleles, 16 were polymorphic. The Jaccard coefficient was utilized to estimate the genetic similarity between the cultivars and the unweigthed pair-group method using an arithmetic average (UPGMA) was used to obtain the phenogram (NTSYS 1.7). The cultivars showed high genetic similarity (>72.5%), and were classified in five main groups: sweet oranges, 'Clemenules' and 'Marisol' mandarins, 'Nova', 'Ortanique', and 'Okitsu' satsuma mandarin |

Osbeck), tangerinas Clemenules e Marisol (C. reticulata Blanco), satsuma Okitsu (C. unshiu Marcovitch) e híbridos Nova [C. clementina x (C. paradisi x C. tangerina)] e Ortanique (tangor provavelmente entre C. sinensis (L.) Osbeck e C. reticulata Blanco), por intermédio de marcadores isoenzimáticos. O polimorfismo foi detectado por eletroforese de proteínas extraídas de tecido foliar em 10 sistemas isoenzimáticos. Foram obtidos 30 alelos, sendo 16 polimórficos. O coeficiente de Jaccard foi utilizado para estimar a similaridade genética entre as cultivares e o método UPGMA para gerar o fenograma por meio do NTSYS 1,7. As cultivares apresentaram elevada similaridade genética (>72,5%) e cinco grupos principais foram detectados: laranjas-doces, tangerinas 'Clemenules' e 'Marisol', 'Nova', 'Ortanique', e satsuma 'Okitsu' |
