Experience

B.146 has been planted in North America recently on a very limited scale.

Treco

Strains

There appear to be subclones of B.146 with different physiological states (juvenile to adult), but they are as yet unnamed.

Observations, suspicions, history

Bud.146 may become a competitor to M.9 and M.27 in the future that is intermediate in size between the two. There remain many questions about the likely future of this rootstock in North America. Bud.146 should be planted on a limited scale for on-farm testing by growers when planting M.27. Bud.146 may be appropriate for use in high density plantings on fertile soils with vigorous scion varieties, particularly in areas where M.27 has insufficient winter hardiness. Susceptibility to fire blight will limit the utility of B.146.
