| RESUMO A produção e o consumo de produtos agrícolas, oriundos do modelo da agricultura orgânica, vêm se expandindo ao longo dos anos. Esse modelo de agricultura necessita cada vez mais de genótipos adaptados ao seu manejo para expandir sua produção e atender as necessidades da população. Sendo assim, o melhoramento participativo tem um papel fundamental no desenvolvimento de cultivares que atendam as necessidades desse modelo. O presente trabalho teve como objetivo avaliar o desempenho de 12 linhagens de tomateiro sob dois sistemas orgânicos. Os experimentos foram conduzidos na Fazenda Escola da Universidade Estadual de Londrina (UEL) (experimento I) e em uma propriedade no distrito de Guaravera (experimento II), Londrina-PR. As seguintes linhagens foram... |

| ABSTRACT Grafting has been considered an important tool to produce tomato in adverse environments. Therefore, the aim of this study was to develop grafting protocols for tomato on rootstocks of Jilo, Cocona and Jurubeba. The work was carried out in a randomized block design, in a factorial scheme (3x2) + 1 with three grafting methods (slant-cut grafting, cleft grafting and splice grafting), combined with two graft ages and rootstocks (depending on the species), and the control. The rootstocks for tomato (Solanum lycopersicum) cv. Santa Clara were: 1) Jilo (S. gilo) cv. Comprido Grande Rio; 2) Cocona (S. sessiliflorum) and 3) Jurubeba (S. jamaicense). The methods were individually studied and the graft length (GL); chlorophyll ‘a’ and chlorophyll ‘b’ in pre... |

| Brazil is the world eighth largest tomato producer and, within the country, the tomato production chain is segmented according to fruit destination: fresh consumption and processing (industrial supply). In contrast, Mozambique does not have a differentiated chain and cultivars are expected to serve both purposes. As there are no tomato breeding programs in Mozambique, cultivars used in the country come from other regions of the world, including Brazil. This paper describes the development and assessment of tomato hybrids with dual-purpose: fresh use and processing. Five tomato genotypes (B13LD, Castone, Massag-72, "Viradoro", and "Rio Grande") were crossed in complete diallel design without reciprocal, and the general and specific combining ability (GCA... |

| An alert system for tomato late blight was validated in an Integrated Production System (IP) in the 2006-2007 and 2007-2008 season in Caçador, Santa Catarina State, Brazil. The late blight is a destructive disease and demands 25 or more fungicide sprayings per season in a Conventional Production (CP) System. For the CP area, the chemical control was according to the growers' production systems and consisted of weekly sprays soon after planting. For the IP area, the criterion for the first fungicide spray was according to Machardy (1972) and for subsequent ones according to Wallin (1962), when the disease severity values (DSV) reached eight points. There was a decrease on the fungicide application in the IP, not only in the number of fungicide sprays... |

| Bemisia tabaci (Hemiptera: Aleyrodidae) biotype B is one of the most limiting pests of tomato crops in the world. Tomato yield is currently dependent on the use of pesticides, which are problematic to farmers, consumers and the environment. A promising alternative to reduce the harmful effects caused by the indiscriminated use of synthetic insecticides is the use of insecticides of botanical origin. This study aimed to evaluate the effect of 3% (w/v) aqueous extracts from different structures of thirteen botanical species on the behavior of B. tabaci biotype B adults, as well as insecticidal activity of such aqueous extracts on B. tabaci eggs, nymphs, and adults infesting tomato plants. A distilled water solution was used as a negative control, and... |

| ABSTRACT The genotypes evaluation in a germplasm bank is essential to determine their commercial or usefulness, as potential parents, in a breeding program. We aimed to detect the genetic diversity of 42 tomato genotypes of cherry type, belonging to the germplasm bank of the Federal University of Uberlândia and, also evaluate their behavior. The experiment was conducted in a greenhouse in randomized block design with 42 treatments and two replications. Ten quantitative traits of agronomic importance were evaluated. The genetic divergence was obtained by multivariate analysis, using the Mahalanobis distance with different clustering methods (UPGMA and Tocher). The hybrids performance was compared by Scott-Knott (p= 0.05) and Dunnett’s test (p= 0.05). UPGMA... |

| ABSTRACT American black nightshade (Solanum americanum) is one of the main weeds for tomato crops. However, no herbicide approved for this crop in Brazil is effective for the control of this species and selective to tomato plants. Therefore, the objective of the present study was to evaluate the selectivity of the herbicide oxadiazon to plants of three processing tomato hybrids and the control of American black nightshade plants. Four trials were installed: one under greenhouse and three under field conditions. The greenhouse trial was conducted in a completely randomized design with four replications, using a 2x5 factorial arrangement consisting of preemergence and postemergence applications of five oxadiazon rates (75, 125, 250, 375, and 500 g ha-1) to... |

| ABSTRACT Tomato crop presents several obstacles that hinder its cultivation, especially the tomato leafminer Tuta absoluta (Lepidoptera: Gelechiidae). To reduce damages caused by this pest, the development of resistant cultivars is one of the main alternatives. In this study we aimed to select tomato genotypes with high acylsugar contents and resistant to tomato leafminer. For this, contrasting F2RC1 genotypes for allelochemical contents, resulting from the interspecific cross between cultivar Redenção with processing characteristics, and the wild species Solanum pennellii accession ‘LA-716’, with high acylsugar contents, were submitted to a test of resistance to tomato leafminer with 14 treatments, being eight genotypes with high acylsugar content and... |
