Abstract

At the Genomics and Strawberry Biotechnology Laboratory at the IFAPA Málaga center, we work on identifying molecular markers—DNA variations—associated with specific traits in the strawberry plant. We are particularly interested in those related to fruit quality and agronomic performance. These markers form the basis for developing genetic tests that help breeders of new varieties select the most desirable traits early and accurately.

Beyond their practical value, identifying these molecular markers provides key insights into the genetic and molecular foundations underlying the variability of the traits studied. As an example, in this article we present the identification of a marker associated with carotenoid content in strawberry fruit. These compounds, in addition to their well-known antioxidant activity, are important for human health because some act as precursors of vitamin A—such as β-carotene and α-cryptoxanthin—while others, such as lutein and zeaxanthin, help protect vision as components of the macular pigments in the eye.

The test we have developed represents a valuable tool for selecting strawberry varieties that are healthier and more nutritionally complete.
