Variety description

10 August 2026

The cultivar is part of the Portuguese national gene pool and is included in collections of local varieties. Genetic analysis of samples showed a high degree of similarity, reaching 97.7%, with the Martaínha cultivar, which indicates their potential identity or close genetic relationship.

The plant is a productive cultivar with an early flowering period. The fruits are large and have a broadly oval shape. Test results indicate the cultivar's susceptibility to ink disease caused by Phytophthora cinnamomi. The cultivar's characteristics may vary depending on the edaphic and climatic factors of the growing region.
