Crop load This sweet cherry showed during the whole evaluation period a very high productivity. An overcropping with smaller fruit sizes is possible. Strict pruning by the grower can prevent this.


In our evaluation this selection didn’t show any off-year.

Particular highlights are the excellent appearance, the full aroma and the maturity time. Especially the high cracking stability and the low susceptibility to pseudomonas characterise this variety.
