Distributions of phenotypic mean values for the S 1 pedigree which consists of 463 F 1 progeny from the cross between the diploid hybrid male ‘Björn’ ( Salix viminalis L. × S. schwerinii E. Wolf) and the diploid female S. viminalis ‘78183’. Distributions are shown for the traits bud burst (a, b), growth cessation (c, d) and leaf senescence (e, f) in field conditions during several years and indoors (g, h).
