According to the DNA study of POM 'Pink Leda' s closest relatives are 'Pipar Hans' in the Bourbon group, 'Erik' in the Damask group and 'Duchesse de Rohan' in the Portland group. Their similarity indices are 64,0, 61,5 and 60,0%. The next closest relatives are 'Blanchefleur' in the Centifolia group as well as three sorts of the Damask group: 'Agathe Incarnata', ?Järnvägeren' and 'Beas Lustiga'.

Léda, Pink form. There is little doubt that this is a sport from the above variety, or it may be that the 'Painted damask' arose from this pink type. They are identical apart from colour; in this form the colour is a soft uniform rosy-pink, darker in the bud and again very fragrant. this form was apparently better known on the Continent, while the 'Painted Damask' was more grown over here.
