<jats:p> Fifteen timothy (Phleum pratense L.) genotypes of similar maturity were grown in simulated sward (100 plants m<jats:sup>−2</jats:sup>), spaced-plant (1 plants m<jats:sup>−2</jats:sup>) and growth room nurseries for 2 yr or harvests. The whole plant in vitro digestibility (IVD) was determined at early heading. IVD values were strongly influenced by growing conditions and highly significant [Formula: see text] year × genotype and harvest × genotype interactions were found. The precision of IVD determination was similar in all nurseries. Correlation between genotype means of simulated sward and other nurseries, although significant [Formula: see text] is some cases, was too low to be of predictive value. Some genotypes tended to rank relatively high in all nurseries, but the relative performance of most genotypes was inconsistent.
