“…Therefore, it is difficult to analyze the divergence between genotypes when applying the Tocher method, since most of them are in only one group. In a study on genetic dissimilarity of 13 tomato hybrids, Luz et al (2016) found similar results 1 -UFU-057F 2 RC 2 10#3.9, 2 -UFU-057F 2 RC 2 8#2.3, 3 -UFU-057F 2 RC 2 10#8.7, 4 -UFU-057F 2 RC 2 7#7.1, 5 -UFU-057F 2 RC 2 7#4.3, 6 -UFU-057F 2 RC 2 13#2.1, 7 -UFU-057F 2 RC 2 13#2.5, 8 -UFU-057F 2 RC 2 10#3.6, 9 -UFU-057F 2 RC 2 8#2.1, 10 -Santa Clara; 11 -UFU-057F 2 RC 2 8#2.4, 12 -UFU-057F 2 RC 2 8#2.2; 13 -UFU-057F 2 RC 2 7#4.7, 14 -UFU-057F 2 RC 2 13#4.2, 15 -UFU-057F 2 RC 2 13#4.1, 16 -UFU-057F 2 RC 2 13#4.4, 17 -UFU-057 and 18 -UFU-057F 2 RC 2 8#2.9…”

The correct characterization of germplasm banks is fundamental for breeders to succeed in breeding programs. Several studies have sought to obtain genotypes with resistance to pests. However, there is no consensus about which methodology is the most appropriate to characterize a germplasm bank of tomato with different levels of resistance to pests. The objective of this study was to compare methods of multivariate analysis for the evaluation of genetic diversity in tomato genotypes with different levels of resistance to pests. The experiments were conducted at the Vegetable Experimental Station of the Federal University of Uberlândia - Monte Carmelo campus (18º 42’ 43.19” South latitude and 47º 29’ 55.8” West longitude, 873 m altitude), in the period from April 2013 to November 2016. Sixteen genotypes were evaluated from the interspecific cross between LA-716 (S. pennellii) versus pre-commercial line (UFU-057) followed by backcrossing and self-fertilization, along with the pre-commercial line UFU-057 (recurrent parent) Santa Clara and the wild accession S. pennellii (donor genitor). The contents of acylsugar, foliar trichomes, South American tomato pinworm and leaf miner repellency tests were analyzed. The experimental design was the randomized block design totaling 76 plots (19 genotypes x 4 blocks). It was concluded that there was genetic variability among the evaluated genotypes. The method of graphic dispersion by principal components revealed a greater power of discrimination. Genotypes UFU-057F2RC27#4.3, UFU-057F2RC28#2.2 and UFU-057F2RC27#4.7 contain the highest levels of acylsugar, resistance to Liriomyza spp. and T. absoluta.

“…The principal component analysis (PCA) is used to identify the variable that contributed the most and contributed the least to the differentiation of the genotypes (Cruz et al, 2012). However, there is no consensus as to the best grouping method for evaluating tomato germplasm with different levels of pest resistance (Luz et al, 2016).…”

“…Das espécies propagadas por sementes, a cenoura (Daucus carota), tomate (Solanum lycopersicum) e a alface (Lactuca sativa), possuem uma grande aceitação no mercado devido suas características nutritivas. A parte comercializada e consumida da cenoura é sua raiz, rica em betacaroteno e fibras, devido seu florescimento ser caracterizado por um amplo período, as sementes ficam expostas a desuniformidades e diferenciação em qualidade fisiológica [4]. Encontra-se entre as dez espécies de hortaliças mais cultivadas no Brasil [4].…”

A utilização de bioprodutos, economicamente viáveis, são de extrema importância na proteção e estimulo de germinação em culturas olerícolas. Este trabalho avaliou o efeito dos microrganismos Azospirillum brasiliense, Bacillus subtilis, Trichoderma harzianum e o produto comercial para tratamento de sementes (Fipronil + Pilaclostrobina e Metil Tiofanato) em sementes e plântulas de alface (Lactuca sativa), cenoura (Daucus carota) e tomate (Solanum lycopersicum). As sementes foram inoculadas antes de serem submetidas à teste de germinação. O tratamento químico mostrou-se ineficiente na proteção da semente de todas as culturas e estimulo de germinação. A T. harzianum aumentou o índice germinativo de sementes de alface, teve melhores valores em tamanho de sistema radicular na cultura do tomate e estimulou a emissão de radícula na cenoura. O B. subtilis destacou-se no acúmulo de matéria seca na cultura do tomate. Os microrganismos B. subtilis e T. harzianum apresentam potencial para tratamento de sementes de hortaliças.

“…Considerada uma das hortaliças de maior importância em escala mundial, o tomateiro (Solanum lycopersicum L.) é amplamente cultivado em todas as regiões do Brasil, mostrando adaptabilidade sob as diferentes condições climáticas do país (ALVARENGA 2013;LUZ et al, 2016). Essa hortaliça desempenha um papel socioeconômico importante no país, devido à geração de renda e emprego (CARVALHO et al,.…”

OLIVEIRA, CAMILA SOARES. Genetic gain estimates by different selection criteria in tomato genotypes under water deficit. 2019. 30 p. Dissertation (Master Program Agronomy/Crop Science)-Federal University of Uberlândia. 1 Tomato crops require high amounts of water and are negatively affected when submitted to water restriction conditions. This may be minimized by using the introgression of genes responsible for controlling the tolerance to water deficits. However, the characteristics related to this type of tolerance are highly complex, which limits selection inferences. The use of selection indexes may be an efficient tool to select genotypes that are more tolerant. This research aims to assess selection indexes based on the estimated genetic gains, as well as to select tomato plant genotypes after they have been submitted to conditions of water deficit through different selection criteria. The research took place at the Horticultural Experiment Station of the Federal University of Uberlandia and was conducted in Random Block Design (RBD) with three repetitions. We used seven genotypes from the interspecific cross between S. pennellii vs UFU-040, Solanum pennelli the donor parent, UFU-040 the recurrent parent and the cv. Santa Clara, totaling ten treatments. Plants were submitted to a moderate water deficit with a matric potential of-34 kPa. We analyzed foliar temperature, the SPAD index, leaf water potential, amount of fruits produced per plant, average fruit weight, yield per plant, incidence of apical rotting, dry matter of the aerial part percentage, root and total, amount of leaves, plant height, and distance of 1 st bunch relative to the substrate. In sequence, analysis of variance, Scott-Knott's and Dunnett's tests for comparison of means, genotypes' relative superiority tests and analysis of selection indexes were performed. The genitor donor, wild accession S. pennellii, was indeed tolerant to water deficit and the Santa Clara cultivar was sensitive to water restriction. This fact reinforces the wild accession's genetic potential of S. pennellii for introgression of genes that promote water deficit tolerance. The T5 genotype presented agronomic potential and satisfactory levels of water deficit tolerance, and it was 58,2% higher in production than the pre-commercial lineage and the UFU-040 recurrent parent. The ideotype-genotype distance selection index is the most appropriate for selection of tomato plant genotypes submitted to water deficit.
