Krymsk®6
- Sizing approximately 70% the size of Mazzard
- High yield efficiency and very precocious
- Good cold hardiness
- Moderate anchorage, support encouraged but not a must

T337
- A M9 sub clone from the Netherland
- Only slightly less vigorous than M9 and resistant to collar rot
Budagovsky 118 (B118)
- A 60-80% of standard size tree that needs no support
- It is very winter hardy
Budagovsky 9 (B9)
- Dwarfing rootstock with very good cold hardiness and some fire blight resistance
- Needs support and can produce early
- Resists collar rot and scab
Budagovsky 10 (Bud 10)
- Sizing compares to M.9 T-337
- High yield efficiency
- Resistance to fire blight and has replant disease tolerance
- Good cold hardiness
Vineland 1 (V.1)
- A fire blight resistant rootstock from Ontario, Canada
- Usually more vigorous than M26 and very winter hardy, more so than B9
Malling-Merton 106
- Rootstock with good anchorage and fair precocity
- A little smaller than M7 but doesn't sucker
- Winter hardy and resistant to woolly aphid
- Sensitive to fire blight
- Susceptability to collar rot requires some management
Malling-Merton 111 (MM111)
