A. Aravanopoulos] Abstract : The relations between heterozygosity derived from a total of 12 variable isoenzyme loci and total above-ground leafless biomass production were examined in four full-sib families of Salix exigua, a willow species important in breeding efforts for short-rotation intensive-culture plantations. Relations were investigated by comparing the performance of heterozygotes with that of corresponding homozygotes in locus by locus comparisons, by investigating multiple regression models with individual loci as independent variables, and by employing the adaptive distance model. All these analytical approaches resulted in the manifestation of the absence of any relations between isoenzyme loci and biomass production. Possible reasons that may account for these results are discussed.
