This study investigates the genetic diversity of eight blueberry (Vaccinium corymbosum) varieties, focusing on a genomic region known as “Scaffold 22”, which contains a high density of genetic variations. The varieties studied include seven Romanian cultivars (“Prod”, “Vital”, “Azur”, “Simultan”, “Delicia”, “Compact”, and “Safir”) and one American variety (“Bluecrop”). Researchers aimed to identify genes related to fruit growth, flavor, and resilience to environmental stress. By examining gene expression and DNA variations within “Scaffold 22”, the study uncovered specific genes that may influence fruit development and quality.
Using whole-genome sequencing, the team detected various types of mutations. The highest number of these genetic differences was found in varieties like “Vital” and “Azur”. Certain mutations in genes involved in nutrient biosynthesis and stress resistance were highlighted as potential markers for breeding programs aiming to improve fruit traits.
The analysis identified both upregulated and downregulated genes during fruit development, some linked to key processes such as ripening, antioxidant activity, and immune response. The findings indicate that the diversity observed within this region can offer valuable insights for breeding new blueberry varieties that meet market demands for taste, nutrition, and resilience.
This research provides a foundation for future breeding initiatives, suggesting that even low-to-medium genome coverage sequencing can yield useful data for identifying genetic markers. By leveraging these genetic markers, breeders can accelerate the development of blueberry varieties that combine desirable fruit traits with resilience to environmental stresses.
