Flowering times of old and new apple varieties in South Tyrol

A suitable pollen donor variety must not only have a pollen compatible with the main vari-ety, the flowering period of both varieties should also overlap sufficiently. The flowering time is crucial for the pollination of apples and thus influences yield and fruit quality. One particular question is...

One particular question is whether new, promising varieties such as Minneiska (SweeTango®) or WA 38 (Cosmic Crisp®) have sufficient overlap of the flowering period with the current main South Tyrolean varieties such as Gala, Golden Delicious, or Cripps Pink (Pink Lady®) and can therefore be grown without an additional pollen donor.
