Our Rootstocks

Bud9

A product of Russian research, B9 (Budagovski-9) is considered by some to be the hardiest of the dwarf rootstocks. It has an ontogenetic resistance to fire blight, i.e., it gains resistance as it ages. Staking and irrigation are strongly recommended for this rootstock.

G41

A new rootstock from the American research program at Cornell University’s Geneva campus, selected for its resistance to Erwinia Amylovora (fire blight). It has been used in Quebec for less than 10 years.

Bud10

A new rootstock from the Russian research program, selected for its enhanced vigour, improved root establishment and resistance to Erwinia Amylovora (fire blight). It has been used in Quebec for less than 10 years.

G11

A new rootstock from the American research program at Cornell University’s Geneva campus, selected for its resistance to Erwinia Amylovora (fire blight). It has been used in Quebec for less than 10 years.

M9 Pajam2 (CEPILAND)

The number one choice of European growers. Considered to be the most vigorous of the M9 types. Promotes good fruit size and colour, as well as early cropping. Recommended for high-density orchards. M9 Cepiland requires support and irrigation.

M26

M26 is a dwarfing rootstock. It is ideal for those seeking greater vigour in a high-density plot on a low-vigour cultivar, such as Honey Crisp (for example). M26 should be staked. It can be planted immediately after the destruction of an orchard since it is not particularly sensitive to nematodes or to apple replant disease.

G935

A new rootstock from the American research program at Cornell University’s Geneva campus, selected for its resistance to Erwinia Amylovora (fire blight) and Phytophthora. It has been used in Quebec for less than 10 years. Comparable vigour to M26.

G969

A new rootstock from the American research program at Cornell University’s Geneva campus, selected for its resistance to Erwinia Amylovora (fire blight) and Phytophthora. It has been used in Quebec for less than 10 years.

M7

M7 is a good choice for more challenging sites. Trees are well-rooted, sturdy and hardy. Slightly smaller than the M106, it has long been the most widely planted semi-dwarf in the United States. Promotes good fruit size, even during dry seasons. Its main weakness is its tendency to produce root suckers.

MM106

MM106 produces well-anchored trees that are larger than M7. Its high productivity has made it the preferred semi-dwarf rootstock of Quebec growers. It rarely produces root suckers. It does best in well-drained soil and should not be planted in moist or clay-rich sites because of its sensitivity to collar rot (Phytophthora).

G890

A new rootstock from the American research program at Cornell University’s Geneva campus, selected for its resistance to Erwinia Amylovora (fire blight). It has been used in Quebec for less than 10 years. Good root establishment. Does not require staking.

MM111

Semi-vigorous. When all other rootstocks have failed, MM111 may be a last-chance option. It performs very well in many types of soils and is the most drought resistant of the rootstocks. However, it is still a fruit tree, meaning that it is not a miracle solution for all types of problems. MM111 is very well anchored and does not need staking.
