Summary: Bacterial spot disease on peppers is caused by Xanthomonas species and leads to yield and quality loss. Greenhouse- and field-grown peppers are both susceptible to bacterial blight caused by xanthomonads. Developing pepper varieties resistant to Xanthomonas species is crucial for sustainable production. In this study, four wild pepper accessions of C. baccatum showed resistance to X. hortorum pv. gardneri strains, which can be used for resistance gene pyramidation in pepper.

Summary: This review systematically introduces the present germplasm resources, cytological examination, and molecular-assisted breeding progress in Lycium species. It also provides insights into the distribution of Lycium species, fertility analysis between species, strategies for quantitative trait locus mapping, and potential traits in different organs. The future direction of goji breeding research is also discussed and concluded.

Summary: Linseed or flaxseed is an ancient industrial crop used for oil and fiber production. The bud fly is a serious pest that affects the production of linseed. In this study, a large collection of linseed germplasm accessions were screened for bud fly infestation, and a subset of resistant accessions was identified. Two accessions, G22 and G23, showed high resistance and stability against bud fly infestation. These accessions can be potential donors for breeding linseed varieties with broad-spectrum resistance against bud fly.

Summary: This study evaluated a collection of barley wild relatives in the field and greenhouse to assess their resistance to fungal diseases. DNA analysis revealed genetic diversity within the collection, and barley-specific SSR markers were shown to efficiently distinguish different species and ecotypes. The findings highlight the value of this collection in breeding programs due to its genetic variability and resistance genes.

Summary: The study found that wild relatives of potatoes are excellent sources of late blight resistance, with some resources containing plants resistant to the disease. Additionally, several species previously unreported to be resistant were discovered, potentially providing new sources of resistance.

Summary: The study successfully overcame the ploidy barrier by using two wild peanut relatives to create a tetraploid with the same genome composition as cultivated peanut. The new allotetraploid ValSten exhibited high resistance to diseases and morphological variations in the early generation. This new germplasm provides a valuable resource for peanut research and improvement.

Summary: This study assessed the genetic diversity of 87 cowpea landraces from Greece. It revealed significant diversity in the local germplasm and detected high levels of genetic polymorphism. The study also identified alleles conferring aphid resistance in some landraces. This highlights the importance of cowpea germplasm collection for breeding efforts and food security in the face of climate change.

Summary: The genetic diversity of 52 kiwifruit wild germplasms was studied using SCoT molecular markers. The genetic relationships were mainly clustered based on place of origin rather than morphological classification or geographical distribution. Disease resistance analysis partially verified the genetic relationships between the wild kiwifruit germplasms.

Summary: In this study, reduced-representation sequencing was used to analyze 378 diverse asparagus genotypes, identifying over 200,000 single-nucleotide polymorphisms. Genome-wide association studies and genome-enabled prediction models were used to study various traits in asparagus. Results showed that cultivated asparagus has a narrow genetic basis compared to wild and hybrid genotypes, which hinders the genetic improvement of this crop.

Summary: This study collected 560 germplasm accessions from the International Rice Research Institute (IRRI) and tested their resistance to the current brown planthopper (BPH) population in China. A total of 105 highly resistant materials were identified. Using specific functional molecular markers, the study also found 23 resistant germplasms that did not contain any of the eight cloned BPH resistance genes, indicating the presence of new resistance genes. One new BPH resistance gene, Bph44(t), was identified in a rice accession and preliminarily mapped to a specific region on chromosome 4. The findings provide valuable resources for identifying new resistance genes and breeding programs against BPH.

Summary: Breeding new high-yielding and stress-tolerant wheat varieties requires the introduction of new genetic diversity, which can be obtained from genebanks and the wild relatives of crops. Pre-breeding, by identifying genetic regions associated with desirable traits, contributes novel beneficial diversity and aids in increasing wheat productivity.
