The bacterium Ralstonia pseudosolanacearum is responsible for one of the main tomato diseases, bacterial wilt. The only effective control measure for this disease is the use of resistant cultivars. The aim of this study was to identify tomato cultivars resistant to Ralstonia pseudosolanacearum. The experiment was conducted in a greenhouse at the Federal Institute of Alagoas - Piranhas Campus. The experimental design used was entirely randomized in a factorial scheme (10 x 2), containing 10 tomato cultivars and two isolates of the species Ralstonia pseudosolanacearum, totaling 20 treatments in three replications, resulting in 60 experimental plots, each containing four plants. Using the diagrammatic scale of bacterial wilt scores, phytopathometry of the disease was carried out using the following variables: Incidence (INC), Bacterial Wilt Index (BWI), Disease Index (DI), Latency Period (LP50), Area Under the Disease Progress Curve (AUDPC) and Infection Rate (IR). These variables were obtained for the 5th − 10th and 15th − 20th day of evaluation. There was a significant interaction between Cultivars x Isolates for the following variables: BWI, AUDPC, IR (5th − 10th day of evaluation) and for BWI, DI and IR (15th − 20th day of evaluation). The variables LP50, INC, IR and AUDPC characterized the start of the bacterial wilt epidemic from the first evaluation interval, regardless of the cultivars and isolates. The cultivar Havaí 7996 was classified as resistant to the isolate CRMRs108, and the cultivar Bartô was classified as moderately resistant to both isolates.

“…The tomato plant (Solanum lycopersicum L.) is one of the most widely grown vegetables in the world, and its fruit is widely used in the cuisine of various countries (Rodrigues et al 2020). Belonging to the Solanaceae family, it is a herbaceous plant that grows from one to three meters in height and can have a determinate or indeterminate growth habit (Kumar 2018).…”

Among the various diseases that affect tomato crops, bacterial wilt stands out due to its high level of damage during the cycle and the difficulty of controlling it. Among the control strategies is the use of resistant cultivars. However, in order to obtain these cultivars, resistance inheritance studies are an essential step. With this in mind, the aim of this work was to study the inheritance of resistance to Ralstonia pseudosolanacearum in the tomato genotypes Yoshimatsu and Hawaii 7996 and to determine whether the resistance loci that govern the trait in these materials are the same. The Yoshimatsu and Hawaii 7996 genotypes and the F1, F2, BC11 and BC21 generations were evaluated in one experiment and 60 F2:3 progenies in a second experiment. The severity of bacterial wilt was assessed using a descriptive scale of scores at 20 days after inoculation. In the Yoshimatsu genotype, the inheritance of resistance to Ralstonia pseudosolanacearum is governed by two major effect genes in recessive homozygosity. In the Hawaii 7996 genotype, the inheritance of Ralstonia psedosolanacearum resistance is governed by a gene with partial dominance action. The greatest contribution of gene effects was due to additive variance. For Ralstonia psedosolanacearum it is recommended to select 20 days after inoculation between and within F2:3 progenies.

O tomate, amplamente distribuído pelo mundo, é uma das principais espécies oleráceas, sendo considerado a segunda hortaliça em volume de produção e consumo. Dessa forma, torna-se primordial pesquisas sobre sistemas de condução da cultura e estudos pós-colheita. Nesse sentido, objetivou-se analisar a qualidade do tomate produzido em ambiente protegido na região da Alta Paulista/SP. O experimento foi conduzido na Unidade Regional de Pesquisa e Desenvolvimento de Adamantina da APTA Regional, em Adamantina/SP, ano 2021. Utilizou-se semente de tomate “Italiano”, de crescimento determinado. Os frutos foram divididos em “comercial (mesa)” ou “descarte (processamento agroindustrial)”. Foram avaliados massa fresca (g), altura e diâmetro médio dos frutos (mm), sólidos solúveis (oBrix) e aproveitamento dos frutos (%). Utilizou-se o delineamento experimental inteiramente casualizado com dois tratamentos e 8 repetições. Os dados foram submetidos à análise de variância para o teste F e as médias comparadas pelo teste de Tukey ao nível de 5% de significância. Observou-se diferença significativa para todas as variáveis, com exceção dos sólidos solúveis. A massa fresca, altura e aproveitamento dos frutos foram os itens com maiores variações quantitativas, respectivamente. Os frutos classificados como “descarte” apresentaram percentual de aproveitamento de 85,25±5,82. Esse resultado mostrou que a produção classificada como “descarte” pode ser vendida para consumo in natura com preço inferior em relação aos frutos selecionados para mesa. Podendo, ainda, ser usado para consumo familiar (como aproveitamento para molho). Concluiu-se que, nas condições em que o trabalho foi conduzido, o tomate “Italiano” avaliado em ambiente protegido na Alta Paulista/SP mostrou-se apto para o consumo destinado à mesa e ao processamento agroindustrial, sendo desta forma recomendado para cultivo comercial.
