Previous issue date: 2013-12-18 / CAPES / The present work had the objective to characterize 59 accessions of tomato of the cherry group regarding its agronomic characteristics and resistance to the late blight and to select those more adapted to the organic agriculture. As standards were used: Carolina, Perinha ?gua Branca, Pending Yashi, Joanna and the hybrids Super Sweet, Sweet Million and Mascot F1. The experiments were conducted under field conditions in the Horticulture Sector of the Federal Rural University of Rio de Janeiro (UFRRJ) from June 2010 to November 2013 during which eight trials were carried out. In the different trials, productivity, number of total fruits, disease progression, morphological characteristics (coloration, shape, number of locules), physical (longitudinal and equatorial diameter), and physicochemical characteristics of fruits (total soluble solids - TSS , titratable total acidity - TTA, pH, TSS / TTA ratio). It was also evaluated the accumulation of dry mass of the stem, leaves and fruits, content and content of nitrogen (N), potassium (K) and phosphorus (P) in the respective organs. It was observed a great genetic variability between the accessions as to the physical and physical-chemical morphological attributes. Promising accesses were selected for use in breeding programs and with great productive potential and potential for cultivation in organic systems. Among these, we highlight the ENAS 1040, ENAS 1037, ENAS 1031 and ENAS 1026 accessions for cultivation in the spring / summer period and the accesses ENAS 1228, ENAS 1214, ENAS 1227 and ENAS 1220 by the highest total soluble solids (?Brix). The accessions ENAS 1121, EAS 1013, ENAS 1143 and ENAS 1029 were distinguished by the production of fruits with differentiated formats and the accesses ENAS 1007, ENAS 1008, ENAS 1037, ENAS 1033, ENAS 1017, ENAS 1036, ENAS 1062 and ENAS 1029 by coloring of the fruits. The accessions ENAS 1227 and 1026 stood out by the partial resistance to the late blight, equivalent to the standards 'Carolina' and 'Perinha ?gua Branca'. The accessions ENAS 1227, ENAS 1216, ENAS 1153 and ENAS 1060 were the ones that stood out the most regarding the resistance to the late blight and productivity. / O presente trabalho teve como objetivo caracterizar 59 acessos de tomateiro do grupo cereja quanto ?s suas caracter?sticas agron?micas e resist?ncia ? requeima e selecionar aqueles mais adaptados ? agricultura org?nica. Como padr?es foram utilizadas: Carolina, Perinha ?gua Branca, Pendente Yashi, Joanna e os h?bridos Super Sweet, Sweet Million e Mascot F1. Os experimentos foram conduzidos em condi??es de campo, no Setor de Horticultura da Universidade Federal Rural do Rio de Janeiro (UFRRJ) no per?odo de junho de 2010 a novembro de 2013 durante o qual realizaram-se oito ensaios. Nos diferentes ensaios, avaliaram-se produtividade, n?mero de frutos totais, progresso da requeima, caracter?sticas morfol?gicas (colora??o, formato, n?mero de l?culos), f?sicas (di?metro longitudinal e equatorial), e f?sico-qu?mica dos frutos (s?lidos sol?veis totais - SST, acidez total titulav?l - ATT, pH, rela??o SST/ATT). Avaliou-se, ainda, ac?mulo de massa seca do caule, folhas e frutos, teor e conte?do de nitrog?nio (N), pot?ssio (K) e f?sforo (P) nos respectivos ?rg?os. Observou-se grande variabilidade gen?tica entre os acessos quanto aos atributos morfol?gicos f?sicos e f?sico-qu?micos. Selecionaram-se acessos promissores para uso em programas de melhoramento e com grande potencial produtivo e com potencial para cultivo em sistemas org?nicos. Dentre estes, destacam-se os acessos ENAS 1040, ENAS 1037, ENAS 1031 e ENAS 1026 para cultivo no per?odo de primavera/ver?o e os acessos ENAS 1228, ENAS 1214, ENAS 1227 e ENAS 1220 pelos maiores teores de s?lidos sol?veis totais (?Brix). Os acessos ENAS 1121, EANAS 1013, ENAS 1143 e ENAS 1029 destacaram-se pela produ??o de frutos com formatos diferenciados e os acessos ENAS 1007, ENAS 1008, ENAS 1037, ENAS 1033, ENAS 1017, ENAS 1036, ENAS 1062 e ENAS 1029 pela colora??o dos frutos. Os acessos ENAS 1227 e 1026 destacaram-se pela resist?ncia parcial ? requeima, equivalente ? dos padr?es ?Carolina? e ?Perinha ?gua Branca?. Os acessos ENAS 1227, ENAS 1216, ENAS 1153 e ENAS 1060 foram os que mais se destacaram quanto a resist?ncia ? requeima e produtividade.
