Abstract

A distinct male cultivar of Salix sachalinensis×S. miyabeana named ‘Canastota’, characterized by rapid stem growth producing greater than 2.7-fold more woody biomass than its female parent ( Salix sachalinensis ‘SX61’), 28% greater woody biomass yield than its male parent (Salix miyabeana ‘SX64’), and 20% greater woody biomass yield than a standard production cultivar, Salix dasyclados ‘SV1’ when grown in the same field for the same length of time (two growing seasons after coppice) in Tully, N.Y. ‘Canastota’ can be planted from dormant stem cuttings, produces multiple stems after coppice, and the stem biomass can be harvested when the plant is dormant. In the spring following harvest, the plant will re-sprout very vigorously, producing new stems that can be harvested after two to four years of growth. This harvest cycle can be repeated several times. ‘Canastota’ displays a low incidence of rust disease or damage by willow sawfly.
