Unique ornamental strawberry cultivar ‘MS1615-01’ with fully double flowers

Since the red-flowered strawberry ‘Frel’ (Pink Panda) was bred by intergeneric crossing with Comarum palustre in the early 1960s, ornamental strawberry breeding has been pursued worldwide.
In addition to new flower colors, strawberries with semi-double, and double flowers have been developed.
However, petal number, even of double flowers, is limited.
On the other hand, NARO has created unique lines with voluminous fully double flowers due to the petalization of all stamens.
Using the fully double-flowered line, we bred ‘MS1615-01’ with high ornamental value. ‘MS1615-01’ is June-bearing, it flowers continuously, and the persistent pink flowers appear above the leaves at full bloom.
The petals do not fall off easily and the flowers last long.
Planted alone, it does not set fruit.
However, planted with pollen-producing common cultivars, it can set fruit in the presence of pollinators.
The bright orange-red globose fruit retains the petals at maturity. ‘MS1615-01’ is the world’s first fully double-flowered strawberry, with an anticipated high appreciation value.
