Agroecology calls for a global approach, integrating scientific, practical, and advocacy dimensions, to redesign agricultural systems based on ecological socio-cultural processes emphasizing biodiversity. This review is grounded the results of DIVERSIFOOD, European H2020 multi-actor research project, explores concept cultivated diversity using various dimensions relevant foster sustainable organic food agro-ecological transition. From evaluation underutilized genetic resources forgotten...
The ECPGR European Evaluation Network (EVA) for Maize involves genebanks, research institutions, and private breeding companies from nine countries focusing on the valorization of maize genetic resources across Europe. This study describes a diverse collection 626 local landraces traditional varieties (Zea mays L.) including criteria selection its phenotypic diversity. High-throughput pool genotyping grouped into groups with threshold 0.6 admixture, while 277 accessions were designated...
Traditional cereals, recognised for their adaptability, high nutritional value, and unique sensory characteristics, have largely been excluded from global food supply chains. Recent shifts in consumption patterns, particularly urban areas, indicate a growing demand high-quality bread, creating new opportunities farmers interested sustainable production techniques traditional varieties. However, challenges such as seed availability, regulatory constraints, marketing strategies, logistical...
Despite the common beans' nutritional and phytochemical value, in Portugal its consumption decreased more than 50% last decade. The present study aimed to characterize phenolic composition of Portuguese traditional varieties corresponding soaked seed fractions (including soaking water). With such purpose, (total content soluble phenolics, flavonoids, proanthocyanidins) vitro antioxidant activity were evaluated raw whole flour 31 bean varieties. was respectively compared flour. Phenolic...
Maize ear fasciation Knowledge of the genes affecting maize inflorescence may lead to better grain yield modeling. fasciation, defined as abnormal flattened ears with high kernel row number, is a quantitative trait widely present in Portuguese landraces. Material and Methods Using segregating population derived from an contrasting cross (consisting 149 F2:3 families) we established two location field trial using complete randomized block design. Correlations heritabilities for several...
Maize is a crop in high demand for food purposes and consumers worldwide are increasingly concerned with quality. However, breeding improved quality complex task therefore developing tools to select better products of great importance. Kernel composition, flour pasting behavior, particle size have been previously identified as crucial maize-based In this work we carried out genome-wide association study identify genomic regions controlling compositional properties maize wholemeal flour.A...
Abstract Modern maize breeding programs gave rise to genetically uniform varieties that can affect maize's capacity cope with increasing climate unpredictability. Maize populations, more heterogeneous, evolve and better adapt a broader range of edaphic–climatic conditions. These populations usually suffer from low yields; it is therefore desirable improve their agronomic performance while maintaining valuable diversity levels. With this objective, long‐term participatory breeding/on‐farm...
Abstract The consumption of fruits and vegetables has been considered very important for human health. This research aimed to study habits from organic farming (OFV) within a convenience sample Portuguese adults, including reasons consumption, most valued mode production sources, frequency use, knowledge about characteristics benefits, information sources. An online questionnaire containing 30 questions was originally developed shared on social networks 300 questionnaires were obtained....
Participatory maize breeding (PMB) was initiated in Portugal 1984 by Dr. Silas Pêgo at Sousa Valley. The VASO project intended to answer the problem facing small farmers, i.e. yield increasing without losing parameters defined farmers polycropping systems maintaining quality traits under a sustainable agriculture. This model is based on Integrant Philosophy, which contrasts with Productivist Philosophy. Philosophy fit multicrop agricultural system that corporate agriculture does not reach...
Previous studies have reported promising differences in the quality of kernels from farmers' maize populations collected a Portuguese region known to produce maize-based bread. However, several limitations been identified previous characterizations those populations, such as limited set traits accessed and missing accurate agronomic performance evaluation. The objectives this study were perform more detailed characterization populations; estimate their broader range environments; integrate...
Odor and aroma, resulting from the perception of volatiles by olfactory receptors, are important in consumer food acceptance. To develop more efficient molecular breeding tools to improve odor/aroma on maize (Zea mays L.), a staple crop, increasing knowledge genetic basis volatilome is needed. In this work, we conducted genome-wide association study unique germplasm collection identify genomic regions controlling wholemeal flour's volatilome. We identified 64 genome candidate genes levels 15...
Abstract “ VASO ” is a Portuguese participatory maize breeding project (1984), where several landraces such as “Pigarro” have been selected both by farmer's (phenotypic recurrent selection) and breeder's approach (S2 lines selection). The objectives of this study were to determine the phenotypic genotypic responses selection using these two different approaches, clarify which extent methods preserve genetic diversity, conclude what preferred method apply in sustainable farming systems....
Participatory selection—exploiting specific adaptation traits to target environments—helps guarantees yield stability in a changing climate, particular under low-input or organic production. The purpose of the present study was identify reliable, low-cost, fast and easy-to-use tools complement traditional selection for an effective participatory improvement maize populations drought resistance/tolerance. morphological eco-physiological responses progressive water deprivation four...
The interest in antioxidant compound breeding maize (Zea mays L.), a major food crop, has increased recent years. However, of compounds can be hampered, given the complex genetic nature these compounds. In this work, we followed genome-wide association approach, using unique germplasm collection (containing Portuguese germplasm), to study basis several antioxidants maize. Sixty-seven genomic regions associated with seven and two color-related traits were identified. Several significant...
Maize is one of the most important crops worldwide and number arable crop in Portugal. A transition from conventional farming system to organic agriculture requires optimization cultivars management, interaction plant–soil rhizosphere microbiota being pivotal. The objectives this study were unravel effect population genotype on microbial communities maize. Rhizosphere soil samples two open-pollinated maize populations (“SinPre” “Pigarro”) cultivated under systems taken during flowering...
The production and consumption of organic products have been increasing in Portugal, as well the European Union a whole. main objective this work is to understand habits medicinal aromatic plants (OMAPs) among Portuguese adults. An online questionnaire was distributed using social networks, resulting collection statistical analysis 300 responses. Of participants who reported consuming OMAPs, 44.3% showed daily pattern. most frequently mentioned OMAPs for fresh were parsley (Petrosselinum...
Soil is a complex environment, where microorganisms play crucial role in the maintenance of soil structure, nutrient cycling and thus quality, relevant for croplands productivity. microbial activity, however, largely determined by water availability, both are affected agricultural management. This study aims to investigate impact irrigation, i.e. different amount application scheduling, on biomass functional structure microbiome (number various ecological-trophic groups)...
