Special Issue Information

Dear Colleague,

The Special Issue entitled “Plant Breeding and Genetics: New Findings and Perspectives” in the International Journal of Molecular Sciences focuses on exploring the latest advancements in the field of quantitative genetics for plant improvement. This Special Issue aims to bridge critical research gaps in the development and deployment of advanced breeding approaches to meet the growing global food security demands, while facing in a sustainable manner more extreme climate change events.

The scope of this Special Issue spans cutting-edge original research and systematic reviews that explore the theoretical and practical aspects of quantitative genetics and plant breeding. The issue seeks to provide a comprehensive overview of the latest methodologies, technologies, and innovations that are driving the field forward, enabling more rapid and precise selection schemes. Diverse disciplines that orbit the plant breeding spectrum are encourage to collide in this Special Issue, a much-needed modern synthesis between the basic and applied genetic arenas to boost the utilization of plant resources and the effectiveness of crop improvement schemes.

By integrating traditional and modern breeding techniques, this Special Issue aims highlighting strategies that can significantly enhance the efficiency and precision of plant breeding programs. This way, the current collection is expected to make significant contributions to the scientific community by providing conceptual frameworks and practical approaches capable to modernize and integrate in innovative manners the fields of plant breeding and quantitative genetics, ultimately supporting global efforts to secure food production, climate change adaptation, and sustainable agricultural practices.

Eggplant (Solanum melongena) is a significant vegetable in the Solanaceae family. Significant progress has been made in genetic diversity analysis and fingerprinting construction for crops such as tomatoes and peppers within the same family, but research on eggplants in these aspects remains relatively limited. Current germplasm identification using fingerprinting primarily relies on traditional SSR markers, which suffer from limited polymorphism and labor-intensive workflows. This study aimed to identify high-quality single nucleotide polymorphisms (SNPs), develop reliable Kompetitive Allele-Specific PCR (KASP) markers for eggplant genotyping, and then conduct fingerprint construction and genetic diversity analysis. The ultimate goals were to achieve a precise identification of eggplant varieties and deeply explore the genetic background and evolutionary patterns of eggplant germplasm. In this study, 49 representative eggplant accessions were re-sequenced. After data quality control, sequence alignment, and multiple rounds of screening, 224 high-quality SNPs were identified. Based on these SNPs, 96 SNPs were selected to develop KASP markers. These markers can provide abundant genetic markers for eggplant genetic research, which are used to deeply explore the genetic background and conduct genetic diversity analysis. After multiple rounds of rigorous verification, 32 core candidate markers were finally screened out. The average polymorphic information content (PIC) and gene diversity (GD) values were 0.36 and 0.46, respectively. Phylogenetic tree, population structure, and principal component analyses divided the 280 eggplant accessions into eight distinct groups. Through the analysis of minimal core markers and core germplasm, 23 core SNP markers and a subset of 56 core germplasm accessions were identified, leading to the establishment of a comprehensive fingerprinting system for all 280 accessions. Our findings provide a foundational genetic resource for eggplant germplasm identification and offer significant support for future breeding efforts. Full article
