We investigated within and between population variation for growth and phenological traits in juvenile Ulmus laevis Pall. (European white elm). In a field trial near Uppsala, Sweden, we assessed quantitative genetic variation and estimated genetic parameters in 19-23 open-pollinated families from each of five populations from across the western and central region of the species range. Traits studied included height, stem diameter and timing of bud flushing, bud setting and leaf fall. Significant pairwise population differences were found for all traits, and most frequently separated northern populations (Sweden and Russia) from more southerly populations (France and Germany). Heritabilities (h**2) ranged from zero to 0.7, and additive genetic coefficients of variation (CVA) from zero to 64.6 %. For most traits in most populations, values for both h**2 and CVA were within the range of previously reported estimates in other broad-leaved trees. Populations differed in terms of their levels of within-population genetic variability, the greatest variability being recorded for the Swedish and the two German populations, and lowest variability in the case of the French population. Height and frost damage were found to be positively correlated with late bud flushing, and significant between-year correlations were recorded for height and leaf fall.
