The aim of this study was to investigate 6 cherry tomato varieties in terms of morphological, instrumental, and sensory attributes. Hungarian cherry tomato landraces have not been investigated in comparison with new commercial varieties for these traits. Parameters investigated were water-soluble antioxidant capacity (FRAP, DPPH, and TEAC), and total polyphenol, vitamin C, β-carotene, lycopene, total soluble solids, and acid contents. Colorimetric measurements as well as sensory analyses were conducted. It was concluded that varied antioxidant assays should be used in parallel to overcome the selectivity of any 1 method. Total phenolic content significantly contributed to results of antioxidant assays for the investigated varieties. The sensory profiles of the 6 cherry tomato varieties have been created. The differences between the products based on the 18 attributes were analyzed by Tukey post hoc test. The biplot of the principal component analysis showed that the sensory panel could discriminate the samples along the principal components. No correlation was found between colorimetric data a* and b* measured from pulp and lycopene, but a negative connection of β-carotene and hue was noted. Total polyphenol content showed correlations with colorimetric results, except for b*. The influence of tomato skin color on color perception is significant as in the present study instrumental data measured from pulp did not match that of the panelists evaluating intact fruit. Instrumental results of sugar content were supported by the ratings of the sensory panel.
In this work, 10 processing type Hungarian tomato gene bank accessions were investigated in a 3-year open-field experiment together with three commercial varieties for quantifying the genotype × environment interaction for their total soluble solids, total acid, dry matter, lycopene, total polyphenol content and antioxidant activity. Results showed remarkable differences of accessions in phytonutrient content over the 3 years (environments). Genotype main effect plus genotype × environment interaction biplots were created for the visualization of the best performing samples and of their relation to a theoretical best variety. Obovate fruit-shaped accessions (especially RCAT031257 and RCAT060349) reached outstanding nutritional results in every environment. According to extremities in weather conditions, two landraces (RCAT060348 and RCAT060349) with higher drought tolerance, and two (RCAT031257 and RCAT029837) less prone to excessive rainfalls were identified. The results can contribute to the enrichment of tomato nutritional phenotypic data banks, facilitating the utilization of gene bank accessions in genomic studies.
The importance of legume crops in global agricultural systems is inevitable; conversely, less than 4% of European agricultural lands are dedicated for these plants. Besides total loss of biodiversity, agrobiodiversity is also in danger. The production of legumes diversifies arable plant production and supports the nutrient management of the agroecosystem, as well as that of the whole ecosystem. Increasing soybean production area means that other pulses are grown on smaller areas, that means a reduced resiliency of the whole production system. Expanding environmental stresses of climate change and intensive agricultural practices are easier to counteract with help of diversity on species and on genetic level as well. As a consequence of climate change and targeted breeding of the last decade, agricultural lands appropriate for soybean production shows an increase in Europe. The self-sufficiency rates of the European Union concerning single protein sources shows fluctuations. The easier utilization of soy-based products as forage displaces the use of other pulses, which are traditionally produced as protein crops. Besides protein flow, these leguminous plants have an important role in different levels of agricultural systems as well. Several recent initiatives aim to reduce the serious protein exposure of the EU. These programs, beyond the introduction and technological development of soybean production, always mention the strengthening of the role of other pulses. In this study, the last decades of EU pulse utilization were analyzed, using crop yield, crop harvested area, certified seed yield, seed production area, number of registered varieties, and the number of scientific publications as indicators to summarize trends of EU field bean, field pea, lupin, chickpea, lentil, and soybean production in the view of targeted protein initiatives.
