“…The results of the ANOVA show that the genotype was significant for 12 out of 18 measured traits, the irrigation for 7 traits, and the environment for 4 traits (mainly fruit color coordinates (fec.L, fec.B, and fec.Hue) and FRAP) (Table S1). These results are in agreement with previous studies describing the growing environment's significant impact on the agronomic behavior of five Penjar genotypes, although it did not significantly affect fruit quality traits [25].…”

“…Moreover, under low watering regimes the water-use efficiency (WUE) of the tomato crop is optimized, although WD produces a negative effect on yield [24]. Thus, the production of LSL landraces under low-input farming practices allows to concomitantly maximize fruit quality and crop efficiency [25].…”

“…Recent success of LSL varieties in the market has triggered the transfer to modern and high-input cropping systems, in some cases diluting their singular quality traits. In the case of the Penjar landrace, current commercial fruits belong to modern and high yielding hybrids produced under high-input and protected cultivation [25,34]. Fruits are consumed not only after prolonged storage but also early after harvest or after a short storage period (30 days).…”

“…Under this new commercial production scheme, both WD and postharvest storage can be used as strategies to increase tomato fruit quality while targeting specific consumers' demands. The effects of the growing environment, water irrigation and fertilization on the agronomic performance of Penjar tomatoes has been recently studied, showing that low-input practices optimize crop efficiency and increase shelf life, boosting the profitability of farmers interested in selling "aged" tomatoes [25]. In this study we present the effects that WD, growing environment (tunnel vs. open-air) and short-term postharvest storage (30 days) have on ripening-related quality traits of Penjar tomatoes.…”

The diversity preserved within the European long shelf life tomato landraces (LSL) is a unique source to design high quality tomato products better adapted to changing environmental conditions and, thereby, to reduce food losses. The adaptation of LSL to water deficit (WD) management practices and their postharvest keeping ability can be used as tools to concomitantly enhance fruit quality and sustainable production. In this study, we investigated the effect of WD conditions and the plant growing environment (open field vs. tunnel) on quality traits of two genotypes of the Penjar LSL variety (modern hybrid (MV) and landrace (LR)). Changes in ripening-related quality traits (fruit ethylene production, respiration rate, firmness, color, soluble solids content, titratable acidity and the content of antioxidants, as well as specific sugars and acids) in response to the different preharvest factors were evaluated at the time of harvest and after a short period of storage (30 days), following actual commercial practices. Significant differences among genotypes were encountered for most quality traits at the time of harvest and higher intra- and inter-environment heterogeneity was observed in the LR than in the MV genotype. In general, Penjar tomatoes exhibit a low physiological activity (ethylene production, 0.56–1.33 µL kg−1 h−1, respiration rate: 0.015–0.026 mg CO2 kg−1 h−1) at harvest. In both genotypes, WD increased to a different extent the fruit external color (redness, lightness) as well as the sensory (SSC) and nutritional (antioxidant capacity) fruit profiles. By contrast, the growing environment had little impact on most fruit quality traits. Postharvest storage only led to a slight reduction in the fruit respiration and ethylene production, lower sugars and acids content, enhanced color and no firmness changes. Overall, the results from this study demonstrate that selecting the appropriate genotypes is the most important step towards the design of high-quality LSL tomatoes, while WD and short-term storage can be used by farmers as a strategy to differentiate the product quality in specific market niches.
