Phenotypic Variation of Sap Sugar Content in Acer Saccharum From Wisconsin

Two sugarbushes (natural stands) in Central Wisconsin were selected for sap sugar assessment in situ over five sap seasons 1980 through 1984. Crown size, dbh and tree height were also measured to permit simple correlation analyses with sap sugar content. Sap sugar content ranged from 1.1 to 14.0% in Wisconsin trees and this amount of variation appears large enough to warrant genetic improvement efforts.
