“…The incorporation of CWRs in food legumes has also proven effective in enhancing adaptive traits and varietal improvement. Lentil (Lens culinaris) breeding has seen advancements in Sitona weevil and Anthracnose resistance, Fusarium wilt, salinity tolerance, earliness, enhancing iron and zinc contents, as well as Orobanche resistance [73]. Chickpea (Cicer arietinum) improvement strategies have focused on resisting Botrytis grey mold, root knot nematode, and addressing water-logging challenges, tolerance to cold, heat, and drought, along with improved micronutrient content (Iron, Zinc, Selenium, etc.…”

Ensuring global food security in the face of climate change is critical to human survival. With a predicted human population of 9.6 billion in 2050 and the demand for food supplies expected to increase by 60% globally, but with a parallel potential reduction in crop production for wheat by 6.0%, rice by 3.2%, maize by 7.4%, and soybean by 3.1% by the end of the century, maintaining future food security will be a challenge. One potential solution is new climate-smart varieties created using the breadth of diversity inherent in crop wild relatives (CWRs). Yet CWRs are threatened, with 16–35% regarded as threatened and a significantly higher percentage suffering genetic erosion. Additionally, they are under-conserved, 95% requiring additional ex situ collections and less than 1% being actively conserved in situ; they also often grow naturally in disturbed habitats limiting standard conservation measures. The urgent requirement for active CWR conservation is widely recognized in the global policy context (Convention on Biological Diversity post-2020 Global Biodiversity Framework, UN Sustainable Development Goals, the FAO Second Global Plan of Action for PGRFA, and the FAO Framework for Action on Biodiversity for Food and Agriculture) and breeders highlight that the lack of CWR diversity is unnecessarily limiting crop improvement. CWRs are not spread evenly across the globe; they are focused in hotspots and the hottest region for CWR diversity is in West Asia and North Africa (WANA). The region has about 40% of global priority taxa and the top 17 countries with maximum numbers of CWR taxa per unit area are all in WANA. Therefore, improved CWR active conservation in WANA is not only a regional but a critical global priority. To assist in the achievement of this goal, we will review the following topics for CWRs in the WANA region: (1) conservation status, (2) community-based conservation, (3) threat status, (4) diversity use, (5) CURE—CWR hub: (ICARDA Centre of Excellence), and (6) recommendations for research priorities. The implementation of the recommendations is likely to significantly improve CWRs in situ and ex situ conservation and will potentially at least double the availability of the full breadth of CWR diversity found in WANA to breeders, and so enhance regional and global food and nutritional security.

“…Molecular tools to assist breeding efforts in lentil are less well developed in comparison with other crops, although progress has been made in germplasm characterization using molecular markers. Genomic research is delayed by the large (4.3 GB) lentil genome size, and progress towards the release of the complete lentil genome sequence is expected to accelerate breeding efforts (Polidoros et al, 2022). Growth and yield can be decoupled in lentil whereby excessive vegetative growth leads to self-shading, reduced pod and seed set, low harvest index and higher risk of disease and lodging.…”

Lentil (Lens culinaris Medik.): A Current Review

Lentil was first cultivated 8000–10,000 years ago and is a protein-rich crop. It is an important dietary component in many Mediterranean and Asian countries but allergic reactions to lentil intake was reported in some countries. Lentil yield is a key and difficult trait to enhance for crop genetic improvement. Several biotic and abiotic variables such as drought, high temperature, salinity, mineral deficiency and fungal diseases limit the production of lentils. Landraces and wild relatives are more tolerant to adverse environmental conditions. Molecular tools to assist breeding efforts in lentil are less well developed in comparison with other crops. Due to its excellent and balanced nutritional composition, the use of lentil flour in bakery, extruded and other products is gaining attention from food technologists and industry. In this review, some valuable information related to lentil is extracted from international articles published in last two years and presented here.

“…Subsequently, centuries of continuous lentil cultivation have led to the development of landraces as fundamental components of Mediterranean farming systems and diet. Lentil is a self-pollinated species and it is generally accepted that several landrace characteristics are co-shaped through the continuous exposure to abiotic and biotic factors of the local environment, including poor soil fertility or exposure to pathogens and farmers' selection to meet local needs [2,3]. On the other hand, breeding programs have released commercial cultivars of legumes including lentil, achieving uniformity and better yields, which are both trends of contemporary agriculture.…”

Lentil (Lens culinaris Medik.) is an essential legume crop providing healthy and nutritious food for people in low- to middle-income countries, worldwide. Lentil roots support symbiotic interactions with soil rhizobia species fostering nitrogen fixation; however, assemblage and diversity of the complete microbial rhizosphere community and the effect of seed genotype and origin remain largely unexplored. In this study we examined, via metagenomic analysis, the effects of seed origin on the rhizosphere’s communities in samples of the famous Greek lentil landrace, Eglouvis, derived from different local farmers and farming systems (including a Gene Bank sample), in comparison to a commercial variety. The landrace exhibited higher rhizosphere microbiome diversity compared to the commercial variety for all indexes. A core microbiome comprised of 158 taxa was present in all samples, while a greater number of unique bacterial taxa was recorded in the landrace samples compared to the commercial cultivar. Notably, landrace samples originated from organic farming had more than double the number of unique taxa compared to conventional counterparts. The study revealed a higher diversity of N2 fixers and archaea, Crenarchaeota and Thaumarchaeota, in landrace samples and particularly in those derived from organic farming, underpinning the distinct recruiting efficiency of beneficial soil microbes by the landrace.
