About this Research Topic
Local landraces are traditional crop varieties cultivated in specific locations and constitute a valuable source for breeding purposes towards the creation of elite cultivars and hybrids. The intensification of modern horticulture has put these genotypes aside, since farmers tend to select hybrids or commercial cultivars due to higher yield, uniformity and marketability. However, this trend despite the short-term benefits for farmers’ income puts in danger valuable genetic resources and increases the threat of genetic erosion, especially when considering the climate change and its implications on modern intensified horticulture. In previous years, there has been increasing concern from consumers regarding food quality, since more and more demand to know the origin of their food by selecting products labelled as Protected Designation of Origin (POG), Protected Geographical Indication (PGI) and Traditional Specialties Guaranteed (TSG).
The proposed Research Topic aims to reveal the importance of local landraces preservation for sustainable horticulture, focusing on special quality features that local landraces present due to their adaptation to specific growing conditions after domestication. The various landraces are very distinct in their quality features based on the region where they are cultivated and the preferences of local markets. Therefore, it is of high importance to highlight these differences and identify genotypes that could be further exploited by producing high added value products and by reinforcing local rural economies.
Potential contributors are invited to submit review or original research papers. Potential topics include, but are not limited to the following:
• Quality features of vegetable local landraces in comparison with commercially available genotypes
• Effect of cultivation practices (fertilization, growing systems) on local landraces quality
• Environmental effects of local landraces cultivation in comparison to conventional genotypes (agrochemical inputs, carbon footprint, sustainability of growing systems)
• Ethnobotanical surveys regarding the recording of local landraces in various regions
• Therapeutic and pharmaceutical properties based on bioactive properties of local landraces
• Chemotyping and chemical fingerprinting of local landraces
Keywords: Local landraces, vegetable production, fruit quality, nutritional value, genetic resources
