“…In order to be sold on the fresh market, tomato fruits should present a minimum size (e. g., in Brazil tomato fruits should have at least 55 mm in diameter 26 ). Since 93-95% of tomato fruit composition is water 27 , production of marketable fruits without irrigation in locations where rainfall is scarce and irregular is impossible. Therefore, breeding for drought resistance in tomatoes aims at developing high-yielding genotypes, adequate in size, which requires a lower but regular water supply throughout the entire growing cycle.…”

Although intensively studied, few works had looked into S. pennellii’s ability to cope with water-deficit conditions from a breeding point of view. In this study, we assessed potential traits of S. pennellii, that had previously been linked to high yields in other plant species, under long-term water-limited conditions and made a parallel with plant yield. For this purpose, the drought-resistant tomato genotypes IL 3–5 and IL 10–1, and the drought-sensitive IL 2–5 and IL 7–1 at seed level, together with both parents the S. pennellii accession LA 716 and the cultivar M82 were kept at 50 and 100% ASW throughout the growing season. Our findings confirm the superiority of LA 716 under water-limited conditions compared to the other S. lycopersicum genotypes in terms of plant water status maintenance. Percentual reduction on plant yield was higher in IL 3–5 and IL 10–1 than in M82 plants, indicating no correlation between drought resistance on germination and plant productive stages. A strong positive correlation was found between fruit yield and A, gs, and Ψleaf at 50% ASW, suggesting these traits as important selection criteria. LT and gmin, LA 716’s most promising traits, did not show a linear correlation with fruit yield under low water regimes. This study unravels traits behind tomato performance under water-limited conditions and should work as guidance for breeders aiming at developing drought-resistant tomato cultivars.

“…bras., Brasília, v.37, n.1, January-March 2019 T omato (Solanum lycopersicum) is the most important fruit vegetable in world agriculture (El Balla et al, 2013). In Brazil, tomato cultivation for in natura consumption is carried out especially in small and medium-sized properties, while processing tomato is cultivated in large areas (Gameiro et al, 2007) with business characteristics, occupying, in the world, the position of main industrialized vegetable.…”

Resistance of processing tomato genotypes to leafminer (Tuta absoluta)

et al. 2019

Tomato crop presents several obstacles that hinder its cultivation, especially the tomato leafminer Tuta absoluta (Lepidoptera: Gelechiidae). To reduce damages caused by this pest, the development of resistant cultivars is one of the main alternatives. In this study we aimed to select tomato genotypes with high acylsugar contents and resistant to tomato leafminer. For this, contrasting F2RC1 genotypes for allelochemical contents, resulting from the interspecific cross between cultivar Redenção with processing characteristics, and the wild species Solanum pennellii accession ‘LA-716’, with high acylsugar contents, were submitted to a test of resistance to tomato leafminer with 14 treatments, being eight genotypes with high acylsugar content and four with low acylsugar content, in addition to the parental. Significant correlations and contrasts were observed between acylsugar contents and traits related to the resistance to tomato leafminer. The genotype RVTA-2010-31-pl#177 presented similar behavior to the wild parental, demonstrating potential to advance in the tomato breeding program for industrial processing with resistance to tomato leafminer.

“…It also has largescale use in the agro-industry for food. Tomato for fresh consumption is cultivated in small and medium-sized properties, while tomato for processing is typically cultivated in large areas (Gameiro et al, 2007). With industries in all consumer centers the processing of tomato is of global importance (Ubierna et al, 2010).…”

Selection of processing tomato genotypes resistant to two spotted spider mite

One of the major problems in cultivation of tomato is the occurrence of pests and diseases. The objective of the research was to select genotypes from the second generation of the first backcross (F2BC1) between the tomato cultivar for processing S. lycopersicum (cv. Redenção) and the wild access S. habrochaites var. hirsutum (PI-127826), with high levels of zingiberene (ZGB), resistant to the twospotted spider mite Tetranychus urticae (Acari: Tetranychidae). From the F2BC1 population. The ZGB content was quantified and five plants with high zingiberene selected (RVTZ 2011-079-117, RVTZ 2011-079-185, RVTZ 2011-079-335, RVTZ 2011-079-345 and RVTZ 2011-079-503) and four with low zingiberene content (RVTZ 2011-079-417, RVTZ 2011-331-460, RVTZ 2011-079-538 and RVTZ 2011-079-548) were selected. Genotypes selected for high and low ZGB content and the parentals S. habrochaites var. hirsutum access PI-127826 and ‘Redenção’ were evaluated for repellency to the twospotted spider mite. There was a significant and inverse correlation between ZGB content and average distances travelled by mites on tomato leaflets. The genotypes of the F2BC1 generation with high zingiberene levels RVTZ 2011-079-117, RVTZ 2011-079-185, RVTZ 2011-079-335, RVTZ 2011-079-345 and RVTZ 2011-079-503 are promising for progress in achieving resistant lines to arthropod pests. Among them RVTZ 2011-079-117 stands out for resistance to twospotted spider mite.
