The market request for organic vegetables has grown recently for their positive impact on healthy diets. Consumers have progressively shown preferences for various combinations of color, size, and shape of pepper fruits. Facilitating communication, collaboration, and participation in the selection of cultivars with superior performance, flavor, texture, and culinary attributes can represent a key tool in breeding for nutritional and culinary traits. The current research started from the premise that organic production involves achieving adequate nutritional and culinary quality of pepper fruits. The study was conducted to investigate traits related culinary quality of pepper genotypes, especially in the ripening phase of fruits, to select the best resources with a high antioxidant content for breeding programs. The biological material represented by nine genotypes of sweet pepper was cultivated in the open fields during 2019 and 2020 at the experimental stations of the Vegetable Research Development Station of Bacau and of Iasi University of Life Sciences. Agricultural practices and intensive breeding focused on yield and stress tolerance have indirectly led to a reduction in the nutrition and flavor of the produce. Complex approaches, including screening of consumer preferences, phenotyping, and use of modern genomics and analytical chemistry tools in breeding, together with participatory farmer-breeder-chef-consumer collaborations, can represent a strategy to facilitate the development of the next generation of crops aimed to meet the growing demands of safe and nutritionally vegetables featured by culinary standards as good flavor, color, and texture.

In response to urgent demand to raise awareness of the nutritional and health benefits of tomato consumption and to advocate for healthy diets through increased sustainable production and consumption of fruits and vegetables, this study is intended to promote a healthy and balanced lifestyle, sharing the best practices of production and consumption. The aim of this research was to compare the effects of the growing system (field vs. plastic tunnel) and of genotype characteristics for organic improved tomato genotypes. The research was carried out in the 2019 and 2020 years on eight improved tomato genotypes. The results showed that the ascorbic acid content presented higher values for organic tomatoes cultivated in the field for all genotypes studied, with an upper limit of 18.57 mg·100 g⁻¹ FW. In contrast, the content in β-carotene and lycopene showed higher values for genotypes grown under plastic tunnel conditions. Significant statistical differences were noticed concerning the mean values of all genotypes according to cultivation conditions (field vs. plastic tunnel) for most parameters excepting total soluble solids (TSS), titratable acidity (TA), maturity index (MI) and flavor index (FI). This highlights the major importance of the selection of some genotypes of tomatoes that respond positively to the organic cultivation system in terms of the presence of the antioxidants compounds (vitamin C, lycopene, and carotene) in representative quantities. Genotype 3 is highlighted by the highest content in carotene (7.4 mg·100 g⁻¹ F.W.) and lycopene (8.4 mg·100 g⁻¹ F.W.) and genotype 5 by the highest content in vitamin C (16.8 mg·100 g⁻¹ F.W.). The results of the study suggest that by applying appropriate techniques for growing organic tomatoes in the plastic tunnel system, the antioxidant substrate can be optimized compared to the results obtained for the field system.
