“…The hybrid Granadero stood out as the highest average genotype for the variables YT, YC, FT and SS by being isolated from the other hybrids in the experiment (Table 3). In the current literature, there are widely variable results regarding processing tomato fruit yield, indicating the existence of differential behaviors of the genotypes in a wide range of Brazilian soil and climate conditions (Aragão et al, 2004;Figueiredo et al, 2016a;Santos et al, 2011;Schwarz et al, 2013).…”

“…In Brazil, in the industrial tomato industry, the main form of breeding used by companies is the introduction of hybrids obtained from breeding programs outside Brazilian soil and climate conditions (Figueiredo et al, 2016a). Hybrids are inserted into a network of experiments and evaluated for countless characters, and the best hybrids end up being registered and commercialized in the national seed market (Santos et al, 2011). Thus, tomato hybrids marketed by multinational corporations may have been obtained from different breeding programs and therefore have distinct genetic bases, which explains the genetic divergence in the hybrids from the same company.…”

“…In the global ranking of tomato producers for processing purposes, Brazil ranks ninth for fruit production and second for fruit yield in the world; in highly technical crops, yields can be over 100 tons of fruit per hectare (Vilela et al, 2012). The prominent position of Brazil in tomato production is due in large part to the adoption of hybrids at the expense of open pollinated cultivars (Figueiredo et al, 2016a;Santos et al, 2011).…”

Genetic divergence among processing tomato hybrids and formation of new segregating populations

Tomato is the most important vegetable species and has a strong bottleneck effect in its domestication and evolution. In exploring the existing genetic variability in commercial germplasm, germplasm has been proven to be an excellent alternative to obtain inbred lines in order to provide superior new hybrids in the future. In this sense, the objective of this study was to estimate the genetic distance among commercial processing tomato hybrids via agronomical and quality postharvest fruit traits with the aim of suggesting promising crosses for the formation of base populations for tomato breeding. Ten hybrids of processing tomato were evaluated in a complete randomized block design with three replicates. In total, eleven agronomic and postharvest fruit quality traits were evaluated. The genetic distances were estimated between the hybrids using the generalized Mahalanobis (

“…Tomato (Solanum lycopersicum L.) is an autogamous plant from which hybrids can be derived, ensuring a series of quantitative and qualitative benefits for producers and consumers (Santos et al, 2011). Currently, hybrid cultivars are planted on virtually the entire acreage of industrial tomato in Brazil (Vilela et al, 2012).…”

ABSTRACT. Heterosis is a highly relevant phenomenon in plant breeding. This condition is usually established in hybrids derived from crosses of highly divergent parents. The success of a breeder in obtaining heterosis is directly related to the correct identification of genetically contrasting parents. Currently, the diallel cross is the most commonly used methodology to detect contrasting parents; however, it is a time-and cost-consuming procedure. Therefore, new tools capable of performing this task quickly and accurately are required. Thus, the purpose of this study was to estimate the genetic divergence in industrial tomato lines, based on agronomic traits, and to compare with estimates obtained using inter-simple sequence repeat (ISSR) molecular markers. The genetic divergence among 10 industrial tomato lines, based on nine morphological characters and 12 ISSR primers was analyzed. For data analysis, Pearson and Spearman correlation coefficients were calculated between the genetic dissimilarity measures estimated by Mahalanobis distance and Jaccard's coefficient of genetic dissimilarity from the heterosis estimates, combining ability, and means of important traits of industrial tomato. The ISSR markers efficiently detected contrasting parents for hybrid production in tomato. Parent RVTD-08 was indicated as the most divergent, both by molecular and morphological markers, that positively contributed to increased heterosis and by the specific combining ability in the crosses in which it participated. The genetic dissimilarity estimated by ISSR molecular markers aided the identification of the best hybrids of the experiment in terms of total fruit yield, pulp yield, and soluble solids content.

The tomato crop plays an important environmental, economic and even social role, especially for creating employment and income. The present work aims to evaluate the effects of potassium (K) drip fertigation and of conventional K fertilization on the tomato crop quality. The experiment was conducted under field conditions, in the period between August 2011 and December 2011, in Fortaleza, CE, Brazil. The experimental design was in randomized blocks in a factorial arrangement and the treatments corresponded to doses (D1 = 200, D2 = 400 and D3 = 800 kg K2O ha-1) and K fertilizing methods (F1 - Fertigation and F2 - Conventional fertilization), plus an additional control (without K fertilization) for each fertilizing method, with four replicates. The following variables were analyzed: fruit firmness (FF), soluble solids content (SS), titratable acidity (TA), pH and SS/TA ratio. K fertilization through fertigation (400 kg K2O ha-1) increases SS and the SS/TA ratio of the tomato fruits. Thus, K fertigation is the most promising method, since it allows the use of a lower K dose.
