| The study aimed to assess the reaction to Tomato yellow vein streak virus (ToYVSV) of determinate-growth tomato breeding lines of the Instituto Agronomico de Campinas (Campinas Agronomic Institute) germplasm collection and to select resistant plants. The experiment was carried out from August 2008 to February 2009 in greenhouse conditions. The geminivirus isolate used was collected in a tomato commercial field, in Sumaré, São Paulo State, Brazil. The experimental design was completely ramdomized blocks, with 25 treatments, four replications, and 30-plant plots. Virus transmission was carried out in cages containing viruliferous whiteflies (Bemisia tabaci B biotype). Plant reaction to the pathogen was evaluated by means of the percentage of symptomless... |

| 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... |

| No Brasil, a batata é usualmente cultivada após a cultura do milho utilizando-se preparo de solo capaz de atingir por volta de 20 cm de profundidade, em que os impedimentos físicos existentes abaixo da camada preparada não são removidos. Desse modo, postula-se que a realização de preparo profundo de solo associado à sucessão com outras poáceas, tais como as forrageiras, seja uma alternativa para proporcionar maior desenvolvimento da batateira. O presente estudo, realizado com a cultivar Atlantic, teve como objetivo comparar o sistema de preparo convencional (PC) de solo adotado para a cultura da batata, em sucessão à cultura do milho, a um sistema de preparo profundo (PP), em sucessão a três diferentes poáceas (milho, capim Marandu capim Tanzânia) quanto à... |

| The objectives of this research were to perform the physical, chemical and sensorial characterization, for hybrid and open pollinated tomato, within the Santa Cruz and Italian groups, aiming fresh consumption. A total of 14 fresh market tomato cultivars was used, six of them being experimental varieties and eight were commercial ones. The experimental design was of randomized blocks with six replicates and five plants per plot. For the chemicophysical analysis, samples of ripe fruits were randomly extracted from five plants in each plot, labeled and maintained under refrigeration at 5ºC until the next day after harvest. Afterwards, fruits of all cultivars were mixed, ground and divided in triplicates to be submitted to the physicochemical analysis. From... |

| ABSTRACT Brazilian market of potato processing has presented expressive development in recent years. However, its expansion is constrained by raw material supply suitable for industrial processing. Selection of adequate cultivars contributes to final product cost reduction as well as its yield and quality improvement. The research aimed to study tuber yield and evaluate its frying potential for shoestrings and chips, of potato cultivars recently introduced in Brazil. Nine potato cultivars (Arizona, Caruso, Destiny, Excelence, Saviola, Agata, Almera, Fontane and Markies) were assessed in an experiment carried out between January and May, 2013, in South-West region of Minas Gerais State, Brazil. 'Arizona' and 'Caruso' cultivars exhibited superior productive... |

| ABSTRACT Tomato is one of the most important crops, the worldwide production in 2012 reached 161.8 million tons. Considering the lack of agronomic information on already available cultivars as well as on the varieties under development by breeding programs for organic systems, the objectives of this work were determine the yield components of 14 tomato cultivars in the organic system, through univariate and multivariate analysis. The experimental design was randomized blocks with six replications and five plants per plot. Evaluations consisted of total, marketable and non-marketable yield and number of marketable fruits per plant, in 2010. We carried out analysis of variance, using test F 5%. The effect of cultivar was fixed and the block effect was... |

| ABSTRACT Yield and disease incidence were evaluated in potato (Solanum tuberosum, cv. Atlantic) after six years of cultivation in succession with corn (Zea mays, cv. ‘AG 6080’) under conventional tillage (CT, depth of tillage: 20 cm) or in succession with three grass species [Guinea grass (Panicum maximum, cv. Tanzânia), Palisade grass (Brachiaria brizantha, cv. Marandu) and corn] under deep tillage (DT, depth of tillage: 70 cm). Total tuber yield was higher in DT in average 36% the value obtained in CT (17.76 t/ha), with no effect of the grass species. Common scab (Streptomyces scabies) incidence was influenced by treatments, the highest (16.9%) and the lowest (9.5%) values being obtained in succession with corn and Guinea grass, respectively, both under... |
