Rosa × kordesii

A hybrid between R. rugosa and R. lucieae was created called Rosa 'Max Graf', but it was diploid and nearly sterile, producing flowers but no fruit.

[1] A selection with double deep pink flowers and repeat bloom, also called 'K01 AgCan' was released by W. Kordes' Söhne in 1951.

[3] Amphidiploid roses can also be created deliberately from diploid-diploid hybrids by using colchicine spray on the growing tips of the plants.

[1] Rosa × kordesii petal extract gel is stable for at least 3–4 months when stored at 5 and 25 °C.

This proved activity of plant showed its importance and prophylactic utility in anti-solar formulation.

The rose 'Max Graf' is a hybrid between two species, R. rugosa and R. lucieae , and is nearly sterile. Amphidiploid offspring from it, and from other roses with the same parentage, have been given the species name Rosa × kordesii .
