Summary: The study focused on describing and evaluating the phenotypic diversity of wild relatives of alfalfa to find germplasm with drought tolerance and improved forage yield traits. New hybrids were created to introduce genetic diversity for breeding programs in warm and cool dry temperate environments. Accessions and pre-breeding lines were donated for conservation and distribution in the Australian Pastures Genebank.

Summary: Crop wild relatives have been underutilized in eggplant breeding, but introgression breeding may help address challenges posed by climate change. Evaluation of eggplant accessions, related species, and interspecific hybrids revealed potential for developing drought-tolerant eggplant cultivars through hybridization.

Summary: Sorghum is the fifth most important cereal crop globally and second in Kenya, crucial for food security in arid regions, with drought tolerance measured by stay-green ability. This study identified the landrace Lodoka as the most drought-tolerant genotype, showing high correlations with yield and chlorophyll content. Genetic diversity using DArT sequencing confirmed that wild relatives and landraces are valuable sources of drought tolerance alleles.

Summary: Pre-breeding using wild relatives can provide useful traits to enhance durum wheat resilience to drought and heat stress. High variation in agronomic and phenology traits can impact grain yield under different stress conditions. Gene introgression from wild relatives can improve wheat resilience to cope with climate change challenges.

Summary: The study reports on a collection mission in Papua New Guinea to develop a wild banana seed bank, focusing on M. acuminata ssp. banksii. The genomic dissimilarity of M. acuminata ssp. banksii was calculated to be 4%, differing at least 5% from accessions in the International Transit Centre. High-throughput phenotyping revealed significant differences in drought avoidance strategies.

Summary: The field trials conducted in Bangladesh and Pakistan with crop wild relatives of carrot revealed new sources of heat and drought tolerance, demonstrating variations in response to climatic stress among germplasm resources. Similar performances in different countries were observed, suggesting potential for developing carrot varieties better adapted to climatic abiotic stress.

Summary: Plant breeders are tackling multiple global challenges by incorporating genetic diversity into new cultivars to improve agricultural performance and enhance nutritional quality of foods. Breeders face strategic challenges in integrating new genetic diversity while preserving important economic traits of individual crops for specific consumer preferences or market needs.

Summary: Pearl millet is a resilient warm-season cereal crop cultivated mainly in Asia and Africa for its gluten-free grains with high nutrients. To improve stress tolerance, breeders are searching for novel genes from diverse sources like crop wild relatives. This article discusses strategies for using alleles to enhance climate resilience traits and emphasizes the importance of using wild relatives for crop improvement.

Summary: Barley is a globally significant crop with various uses, but its productivity is limited by multiple stresses. Crop wild relatives, especially Hordeum vulgare ssp. spontaneum and H. bulbosum, are important genetic resources for developing new varieties. In experiments, some wild barley accessions showed resistance to multiple diseases, but no lines performed better in terms of yield than the best checks. Further efforts are needed to strengthen pre-breeding work, evaluate more wild Hordeum accessions, and select elite germplasm for barley breeding programs.

Summary: This study identified wild Lathyrus species with resistance to common broomrape species, Orobanche crenata Forsk. and O. foetida Poir, in Morocco and Tunisia. Different species of Lathyrus showed varying degrees of resistance to the parasitic weeds, contributing to potential breeding efforts against Orobanche crenata and O. foetida.

Summary: Pearl millet is a hardy warm-season cereal crop cultivated in the semi-arid tropics of Asia and Africa, facing challenges such as heat stress and drought. The study developed introgression lines with improved traits and identified potential hybrids resistant to blast disease, highlighting the importance of wild species phenotyping for prebreeding work.

Summary: Developing nutrient-rich crop cultivars is an economical strategy to combat malnutrition, and this study identified genetic variability for protein and mineral concentrations in different chickpea and wild Cicer species. Promising species for high seed protein and mineral content were identified, particularly C. chorassanicum, C. judaicum, C. yamashiatae, and C. pinnatifidum. Wild Cicer accessions, such as ICC17141, ICC17269, ICC17303, ICC17261, ICC17262, ICC20236, ICC17117, and ICC17281, were found to be promising for multiple seed nutrients.
