Abstract: A distinct female cultivar of Salix viminalis×(Salix sachalinensis×Salix miyabeana) named ‘Preble’, characterized by rapid stem growth producing 29% more woody biomass than the average of three current production cultivars (Salix×dasyclados ‘SV1’, Salix sachalinensis ‘SX61’, and Salix miyabeana ‘SX64’) when grown in the same field for the same length of time (three growing seasons after coppice) in two different trials in Constableville, N.Y. and Middlebury, Vt. ‘Preble’ 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 repeatedly after two to four years of growth. ‘Preble’ displays a low incidence of rust disease and is not damaged by potato leafhoppers.

Abstract: A distinct female cultivar of Salix purpurea×Salix miyabeana named ‘Millbrook’, characterized by rapid stem growth producing 9% more woody biomass than one of its parents (‘SX64’) and 2% more biomass than a current production cultivar (‘SV1’). ‘Millbrook’ produced greater than 2-fold more stem biomass than two other current production cultivars, ‘SX67’ and ‘SX61’. ‘Millbrook’ 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. The stem biomass can be chipped and burned as a source of renewable energy, generating heat and/or electricity. ‘Millbrook’ displays a low incidence of rust disease.

Abstract: A distinct male cultivar of Salix purpurea×S. miyabeana named ‘Oneida’, characterized by rapid stem growth producing 2.7-times greater woody biomass than one of its parents (‘SX67’) and greater than 36% more biomass than current production cultivars (‘SV1’ and ‘SX64’). ‘Oneida’ 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. The stem biomass can be chipped and burned as a source of renewable energy, generating heat and/or electricity. ‘Oneida’ displays a low incidence of rust disease or damage by beetles or sawflies.

Abstract: A distinct male cultivar of Salix purpurea named ‘Fish Creek’, characterized by rapid stem growth producing greater than 30% more woody biomass than either of its parents (‘94001’ and ‘94006’) and 20% more biomass than a current production cultivar (‘SV1’). ‘Fish Creek’ 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. The stem biomass can be chipped and burned as a source of renewable energy, generating heat and/or electricity. ‘Fish Creek’ displays a low incidence of rust disease or damage by beetles or sawflies.

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.

Abstract: A distinct female cultivar of Salix viminalis×Salix miyabeana named ‘Owasco’, characterized by rapid stem growth producing greater than 49% more woody biomass than one of its parents (‘SX64’) and 39% more biomass than a current production cultivar (‘SV1’). ‘Otisco’ produced greater than 2.7-fold more stem biomass than two other current production cultivars, ‘SX67’ and ‘SX61’. ‘Owasco’ 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. The stem biomass can be chipped and burned as a source of renewable energy, generating heat and/or electricity. ‘Owasco’ displays a low incidence of rust disease and is not damaged by potato leafhoppers.

Abstract: A distinct female cultivar of Salix viminalis×S. miyabeana named ‘Tully Champion’, characterized by rapid stem growth producing greater than 25% more woody biomass than two current production clones (Salix dasyclados ‘SV1’ and Salix miyabeana ‘SX64’), more than 2.5-fold greater biomass than one of its parents (Salix miyabeana ‘SX67’), and nearly 3-fold more biomass than another production clone (Salix sacchalinensis, ‘SX61’) when grown in the same field for the same length of time (two growing seasons after coppice) in Tully, N.Y. ‘Tully Champion’ 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 repeatedly after two to four years of growth. ‘Tully Champion’ displays a low incidence of rust disease and is not damaged by potato leafhoppers.

Abstract: A distinct female cultivar of Salix viminalis×S. miyabeana named ‘Otisco’, characterized by rapid stem growth producing greater than 42% more woody biomass than one of its parents (‘SX64’) and 33% more biomass than a current production cultivar (‘SV1’). ‘Otisco’ produced greater than 2.5-fold more stem biomass than two other current production cultivars, ‘SX67’ and ‘SX61’. ‘Otisco’ 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.
