Fruit tree rootstock variety from ANFIC
The Krymsk™ Cherry rootstocks are similar in vigour to other semi-dwarfing cherry rootstocks.
Key advantages are:
- More stress tolerant than other semi-dwarfing rootstocks (heat/low humidity, difficult soils and poor growing conditions). More disease tolerant eg Pseudomonas and crown gall.
- Krymsk™ rootstocks perform well in Bakersfield, California which is a difficult cherry growing area.
- Fruit size is the same as on semi-dwarfing and Mazzard rootstocks.
- Currently selling 250,000 trees each per year of Krymsk™ 5 and 6 in the USA. Some of the largest WA, USA growers are now only planting Krymsk™ cherry rootstocks and nothing else.
- Minor disadvantages include:
- Krymsk™ 5 and 6 are virus sensitive so virus-free budwood is required. (Krymsk™ 7 is not virus sensitive).
- The Krymsk™ rootstocks have moderate suckering which should not be a problem for growers.
