Editorial: Rediscovering local landraces: shaping horticulture for the future, volume II
| Resumo: | The ongoing climate change accompanied by weather extremes has increased uncertainty in the crop production sector, with a severe impact on yield and quality of crops (FAO, 2022). Moreover, the increasing world population, along with the continuous reduction of available irrigation water and agricultural land degradation due to anthropogenic activities, necessitates the redesign of the existing farming systems through the integration of valuable and underexplored genetic material, such as the local landraces of various vegetable species. Local landraces are cultivated in restricted regions and have been adapted over the years to specific growing conditions (soil and climate characteristics). Usually, they possess high genotypic diversity, which allows the crops to overcome the pressure from abiotic and biotic stressors from time to time (Conesa et al., 2020), while increasing on-farm agrobiodiversity at the same time (Conversa et al., 2020). For this reason, this genetic material is highly valuable for breeding purposes and the selection of new genotypes with improved characteristics (Formisano et al., 2012). Their use is becoming more and more limited due to the intensification of crop production sections and restrictions from marketing standards mostly related to visual appearance and the uniformity of the final product. However, the current trends show increasing interest not only from farmers who seek alternative farming options in the climate change scenario but also from consumers who seek products of known origin and high quality that have been produced in a sustainable manner. |
