Cherry rootstocks
Mazzard (Prunus avium)
- Used worldwide and adaptable to a wide range of soil and environmental conditions
- Vigorous but can be maintained at 10-12 feet
- Not precocious unless vigorously trained
Mahaleb (Prunus mahaleb)
- Vigorous rootstock used worldwide
- Can be precocious and is more winter hardy than Mazzard
- Has good drought tolerance but incompatible with some varieties
MxM14 (Prunus mahaleb x Prunus avium)
- Semi vigorous and about 60% of Mazzard size
- Precocity is good and has tolerance to Pseudomonas
Peach rootstocks
Lovell
- Long lived (12-15 years)
- Good winter hardiness (depends on how quickly the temperature drops and at what time of the year)
- Disease-resistant
Bailey
- Moderate size tree
- Uniform growth
- Good winter hardiness (depends on how quickly the temperature drops and at what time of the year)
- Higher cumulative yield than Lovell
Apple rootstocks
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
Nicolai 8 (Nic 8)
- A sub clone of M9 from Belgium
- The least vigorous of the Nicolai series and comparable to FL56
Nicolai 19 (Nic 19)
- Medium vigor of the Nicolai series
- Precocious
- About the same size as M9
- A sub clone of M9 from Belgium
Nicolai 29 (Nic 29) U.S.P.P. applied for
- Most vigorous of the Nicolai series
- Precocious
- Slightly larger than M9 and needs support
- A sub clone of M9 from Belgium
Fluren 56 (FL56)
- A M9 sub clone from the Netherlands that is about 15% less vigorous than M9
- It is similar in size and behavior to B9
- There are reports of more root suckers than in other M9 clones
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
Geneva 30 (G30)
- A fire blight resistant M7 size tree from Cornell University
- It is precocious and needs support
Supporter(TM) 4
- Sizes like M26 with good precocity, similar to M9
- It needs support but doesn't sucker or form burr knots
- Less sensitive to fire blight and collar rot than EMLA 26 and good winter hardiness
Malling 7 (M7)
- A semi dwarf root about 5-10% larger than M26
- Root suckers are the main detractor
- In most soils tree support is a good idea, particularly in new plantings
- This rootstock is winter hardy and adapts to a wide range of soils and management styles
Malling 26 EMLA(M26)
- Standard semi dwarf rootstock, widely planted where more vigor is required
- Precocious but fire blight susceptible
- This is a good rootstock for medium density orchards with lower vigor scions
- A clone of EMLA 26, M26 Adult, is a European selection that has fewer burr knots but other growth characteristics are the same
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)
- Produces trees 60-80% of standard depending on scion vigor
- Doesn't need support and produces well
- This rootstock is somewhat drought tolerant
