Abstract
La Marina Alta, a region in the Alicante province of Spain, exhibits significant variability in the grapevine cultivar ‘Muscat of Alexandria’. Within the selected clones in this region, CM59 stands out for its medium-sized berries, which are notably whiter than those of other Muscat clones in the area.
CM59 also distinguishes itself through various agronomical traits, including differences in maturity and resistance to pests.
Grown in different old vineyards, this clone demonstrates a favorable compatibility with various rootstocks and is particularly valued for table consumption.
Despite its significance, there are limited references to this specific type of Muscat of Alexandria in available bibliographic resources, underscoring the importance of its characterization.
This study focuses on reporting ampelographic traits and general agronomic aspects of the CM59 clone.
Additionally, by analyzing nearly 40,000 single nucleotide polymorphisms (SNPs) identified in a genotyping-by-sequencing (GBS) assay involving a small set of Muscat of Alexandria clones, approximately 2,600 SNPs were found to differ between CM59 and the other clones.
In-depth analysis revealed those that could have a moderate impact (non-synonymous) or high impact, primarily involving start site loss or stop site gain.
Noteworthy that among these later are genes associated with proteases controlling stomatal development, responses to abiotic and biotic stresses, expression regulation at pre- and post-translational levels, protein folding, transporters, grape pigmentation, apical development, regulation of flowering, growth, and signaling pathways.
This comprehensive exploration of genetic variations provides valuable insights into the unique characteristics of the CM59 clone, contributing to our understanding of the genetic basis of its distinctive traits.
