Abstract(s)
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.
