| O grupo varietal Brasília apresenta ampla adaptação para cultivo em regiões/épocas de clima mais quente e tolerância às principais doenças que afetam o cultivo da cenoura em regiões tropicais e subtropicais ("queima-das-folhas" e as galhas radiculares causadas por nematóides do gênero Meloidogyne). No entanto, algumas cultivares desse segmento apresentam elevada incidência de defeitos genéticos que afetam a qualidade visual, sensorial e nutricional das raízes. A Embrapa Hortaliças desenvolveu a cultivar BRS Planalto, visando minimizar parte destas limitações. 'BRS Planalto' é uma variedade de polinização aberta que foi desenvolvida a partir da cultivar de cenoura 'Brasília'. Foram realizados 18 ciclos de seleção recorrente, com base no desempenho de... |

| ABSTRACT The demand for cultivars suitable for processing, especially as frozen French fries, is increasing in Brazil. The Canadian expertise is high regarding the development of cultivars with processing characteristics; however, the growing conditions in Canada are quite different from those observed in Brazil. Thus, the aim of this work was to evaluate the performance of Canadian potato clones for their tuber yield, frying quality, plant vigor, and plant cycle, as potential new cultivars or to be used as a new source of variability for crosses. The experiments were conducted in Pelotas-RS and Canoinhas-SC, Brazil, in spring 2017. A set of 12 advanced Canadian potato clones from the Centre de Recherche Les Buissons, QB, Canada, were compared to three... |

| ABSTRACT Potato is responsive to intensive agricultural input use; however, it can be produced in less intensive production systems (such as the organic system) by using appropriate production techniques and genotypes adapted to this system. This study aimed to evaluate the performance of advanced potato genotypes for tuber yield under conventional and organic production systems, in order to select potential genotypes to become new cultivars adapted to these systems. Fifteen advanced potato clones and two controls were evaluated under organic and conventional production systems, in 2016 and 2017, in Brasília-DF, Brazil. The experimental design was randomized blocks with three replicates and plots composed of two rows with 10 plants each, spaced 0.35 m... |

| Verificou-se a efetividade de caracteres fenotípicos na caracterização e dissimilaridade, bem como a distância genética entre populações melhoradas e cultivares de cenoura. Os experimentos foram conduzidos na Embrapa Hortaliças, Distrito Federal. Seis genótipos de cenoura, sendo três populações melhoradas (712467, 712473 e 712464), e três cultivares (Brasília, BRS Esplanada e BRS Planalto) pertencentes ao grupo Brasília, foram avaliadas nas safras de verão de 2007/2008, 2008/2009, 2009/2010. Os experimentos foram instalados em delineamento de blocos ao acaso com duas repetições e parcelas de 1 m² de área útil. Aos 100 dias após semeio, foram colhidas 25 raízes por parcela e avaliadas individualmente para diâmetro do xilema da raiz, e para caracteres que... |

| ABSTRACT Selection of more productive carrot genotypes is fundamental for crop breeding programs aiming to increase productivity and reduce cost production. Thus, the aim of this work was to evaluate gains from direct selection and to measure its effects on other agronomic traits of interest in carrots. Thirty six carrot genotypes were evaluated in two experiments: the first, sown in the second half of November 2016 and the second one in the first week of March 2017. The experimental plots covered a useful area of 1.5 m2, in transversal rows and 0.10-m double spacing between single rows x 0.20-m between double rows in a randomized block design with 3 replicates. At 90 days, the incidence of leaf blight was evaluated using a note scale and 100 days after... |

| ABSTRACT The objective of this study was to evaluate the yield potential, frying quality, plant vigor, and vegetative cycle of Chilean potato clones, aiming to identify those with potential to become new cultivars or to be used in breeding programs. The experiments were conducted in Pelotas-RS and Canoinhas-SC, Brazil, in spring 2017. A set of 37 advanced potato clones belonging to the Agricultural Research Institute of Chile (INIA) was compared to commercial cultivars Agata, Asterix and Atlantic. A randomized complete block design with three replications of two rows with 10 plants each was used. Tuber yield, frying quality, plant vigor and vegetative cycle traits were evaluated. The data were submitted to analysis of variance, test for grouping means, and... |
