Summary: The potential yield of maize and other major crops is limited by various factors, including parasitic weeds such as Striga spp. Breeding for Striga resistance is considered to be the most economical and sustainable approach for resource-poor farmers and the environment. Understanding the genetic and genomic resources and components of Striga resistance is crucial for the genetic analysis and breeding of maize varieties with desirable traits. This review discusses the genetic and genomic resources, research progress, and opportunities in the genetic analysis of Striga resistance and yield components in maize for breeding.

Summary: The Agronomic Institute of Campinas (IAC) in Brazil developed a grapevine breeding program in the 1940s to create new grape varieties suitable for the country's tropical and subtropical regions. After 50 years and over 2,000 crosses, only 130 hybrids remain in the IAC collection with little information about their genetic characteristics. This study genotyped these hybrids and assessed their genetic diversity and population structure, as well as identifying their true parentage and verifying their pedigrees.

Summary: Micronutrient malnutrition is a serious threat to the developing world's human population, especially those relying on a cereal-based diet. Millets, as versatile crops, have the potential to address this issue due to their tolerance to abiotic stresses and rich nutritional characteristics. This review highlights recent genetic and genomic innovations in improving grain micronutrient density in millets, as well as advancements in high-throughput phenotyping and genetic diversity exploration. The integration of omics approaches, such as genomics and proteomics, can help develop nutrient-dense varieties for the future.

Summary: Small populations can suffer from high inbreeding rates and associated genetic issues. The Retriever and Pointer software have been developed to assess inbreeding levels and simulate the effects of genetic management measures. These tools can be used for genetic management of various captive populations and have potential applications in education.

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 genus Allium contains nearly 1000 different species, with onions and garlic being the most important edible plants that are cultivated and consumed globally. However, due to various constraints such as biennial nature, high crossability, and limited reproductive capacity, these plants have not received systematic and focused research. Induced mutagenesis is the best choice for creating genetic variation, especially in the context of climate change, to develop varieties with better adaptability to nutrient and growth conditions.

Summary: This study aimed to produce a high-density linkage genetic map of pitaya using whole genome resequencing, resulting in 6434 high-quality polymorphic SNP markers and 11 linkage groups. The linkage map, in combination with genomic resources, will facilitate quantitative trait mapping, evolutionary studies, and marker-assisted selection in the Hylocereus species.

Summary: Carotenoids are important for human health and industrial quality in durum wheat. Esterification of carotenoids, particularly lutein, in durum wheat provides stability and enhances biofortification. Identifying durum wheat accessions with esterification ability is a significant advancement for increasing carotenoid content. Variability in specific carotenoids presents new opportunities for biofortification breeding.

Summary: This study characterized 150 accessions of Spanish durum wheat collection and identified genetic regions on chromosome 2B that are involved in the control of stem traits and lodging tolerance in both durum and bread wheat. The study also highlighted the potential of these durum wheat landraces as donors for enhancing lodging tolerance and resistance to wheat stem sawfly. The identified marker-trait associations for stem-related traits could be used as a reference for further marker development.

Summary: Bread wheat has traditionally been selected for white flour, resulting in low grain carotenoid content. In contrast, high yellow pigment content is desired for durum wheat used in pasta production. This study transferred carotenoid-related genes from durum to bread wheat and successfully developed bread wheat pre-breeding lines with enhanced grain carotenoid content. These lines have the potential to become new bread wheat varieties or be used in breeding programs.

Summary: The content of yellow pigment in durum wheat grain is mainly due to the accumulation of carotenoids, which gives pasta its bright yellow color preferred by consumers. Carotenoids are also important nutrients with essential biological functions for human health. The identification of the XAT-7A1 gene responsible for carotenoid esterification in durum wheat is a necessary step for breeding programs to enhance carotenoid levels in wheat varieties. The focus should be on the Type 1 XAT-7A1 haplotype, which has been associated with high levels of carotenoid ester production.
