Little progress has been made in translating the increased awareness of neglected and underutilized crops into a viable tool for advancing not just sustainable development in rural areas but also sustainable agricultural and secured food systems. This is caused, in part, by a lack of understanding the importance of several underutilized crops that are currently in cultivation. Among underutilized crops, grasspea (Lathyrus sativus) is an orphan legume crop with great agronomic potential due to its suitability for a variety of sustainable food and feed production systems throughout the world’s semi-arid and arid regions and its high protein content. The current study presents a SWOT (strengths, weaknesses, opportunities, and threats) analysis to unravel the following: What are the strengths and weaknesses of Lathyrus spp. cultivation, what factors are opportunities or initiatives that encourage the adoption of the crop by growers, and what factors are disincentives or threats that prevent its adoption? What strategies could help expand cultivation? We use data from a questionnaire survey of farmers in Central Greece (Thessaly) to examine their attitudes and perceptions with regards to the above questions. The outcome of this study strongly suggests that farmers are willing to adopt the new Lathyrus spp. cultivation if they are assisted via contractualization, training, and new financial tools.

Landraces and indigenous varieties comprise valuable sources of crop species diversity. Their utilization in plant breeding may lead to increased yield and enhanced quality traits, as well as resilience to various abiotic and biotic stresses. Recently, new approaches based on the rapid advancement of genomic technologies such as deciphering of pangenomes, multi-omics tools, marker-assisted selection (MAS), genome-wide association studies (GWAS), and CRISPR/Cas9 gene editing greatly facilitated the exploitation of landraces in modern plant breeding. In this paper, we present a comprehensive overview of the implementation of new genomic technologies and highlight their importance in pinpointing the genetic basis of desirable traits in landraces and indigenous varieties of annual, perennial herbaceous, and woody crop species cultivated in the Mediterranean region. The need for further employment of advanced -omic technologies to unravel the full potential of landraces and indigenous varieties underutilized genetic diversity is also indicated. Ultimately, the large amount of genomic data emerging from the investigation of landraces and indigenous varieties reveals their potential as a source of valuable genes and traits for breeding. The role of landraces and indigenous varieties in mitigating the ongoing risks posed by climate change in agriculture and food security is also highlighted.
