“…Tomato breeding programs aimed at exploring hybrids perform many crossings between lineages with the intention of forming hybrids that have concomitant high yield, high soluble solids content (SS), proper titratable acidity (TA), high lycopene content (LIC), and a high content of reducing sugars (RS), as well as resistance to the major crop diseases. Hence, the need to involve multiple traits into the same individual hinders plant breeding and requires a preliminary assessment of these characters in genotypes, which eventually form the base population for the extraction of elite inbred lines (Boiteux et al, 2012;Paula et al, 2015).…”

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 (

“…Three harvests of fruits were carried out from the breaker stage of maturation (light green fruit with the first appearance of pink, red or yellow covering up to 10% of its surface), the first being at 94 DAT (Paula et al, 2015). The following two harvests were completed in 10-day intervals.…”

The possibility of cultivation without the use of chemical insecticides or reduction thereof, associated with the requirements of consumers has motivated growers to return to the practice of bagging fruit, but it is possible that this technique causes changes in the visual and organoleptic characteristics of fruits. The objective of this study was to evaluate possible changes in postharvest characteristics in 'Valerin' tomato fruits produced inside nonwoven bags (TNT) and validate the best period for bagging. The fruits came from commercial cultivation of tomato plants, located in "Ubajara", "Ceará" State, Brazil. The experiment design used 2 × 4 factorial randomized blocks with five repetitions. The factors considered two types of insecticide use: 1-Plants treated with insecticides and 2-Plants not treated with insecticides, and four ways to bag the bunches with nonwoven fabric (TNT): T1-Bagging flower, T2-Bagging the bunches with fruits with a 1.5 cm diameter, T3-Bagging the bunches with fruits with a 3.0 cm diameter, and T4-Bunches not bagged (control). Variations in color parameters (brightness and hue angle) and firmness did not compromise the fruit quality when bagging was conducted in the flower stage (T1) or when the fruits had a 1.5 cm diameter (T2). The other parameters (titratable acidity, total soluble solids, total carotenoids, lycopene and ß-carotene) showed no change when compared to the control. Bagging the tomato bunches in the flower stage or when the fruits had a 1.5 cm diameter did not change the postharvest quality.Additional key words: Solanum lycopersicum, pest control, fruit quality.

“…According to Paula et al (2015), fruits harvested with a yellowish-green tinge have a longer postharvest life and a higher resistance to transport. However, fruits have better characteristics for taste quality when they complete their maturation (red stage) while still on the plant.…”

“…The fruit standard required by the Brazilian market excludes fruits with a diameter less than 40 mm and greater than 100 mm (Paula, 2015). The intermediate classes are preferred because of their convenience during the preparation of food.…”

La adición de compost orgánico (CO) a la cáscara de arroz cruda (CAC) podría traer beneficios productivos al cultivo del tomate, al conferirle mayor poder buffer y capacidad de retención de agua al sustrato en sistemas con recirculación del lixiviado. Asimismo, es necesaria la elección de variedades que respondan positivamente a la tecnología propuesta. El objetivo del presente trabajo fue estudiar los efectos de la adición del CO a la CAC sobre las características físicas y químicas del sustrato [a través de la comparación entre la CAIN (100%) y la mezcla de CAC (80%) + CO (20%)] sobre el crecimiento y el comportamiento productivo de cuatro híbridos de tomate salado [Ivety, Sofhia-F3, Sheila Victoria y Lumi (Sakata® Seed)]. Se evaluaron las características químicas y físicas de los sustratos, la producción (tamaño, número, peso y rendimiento de frutos a lo largo de la cosecha), partición de la materia seca y la concentración de sólidos solubles totales (SST). La adición de CO mejoró las características físicas y químicas del sustrato, pero no afectó las principales variables del crecimiento y de la producción de la hortaliza. Las cuatro variedades presentaron similar crecimiento y rendimiento de frutos pero Sheila Victoria presentó la mayor concentración de SST. El rendimiento obtenido se considera alto, con rangos que van desde 6,3 kg/planta para las variedades Sophya-F3 y Sheila Victoria, 6,5 kg/planta para la variedad Lumi, y 7,6 kg/planta obtenido con la variedad Ivety. Los resultados indican que es innecesaria la adición de CO a la CAC y que las cuatro variedades se adaptan de forma similar al sistema propuesto.
