Tillering is enormously variable in the genus Lolium. Exploitation of tillering characteristics in breeding programs requires a systematic characterization of this trait at the between-species, within-species, and within-cultivar levels. We have analyzed tillering in forage and turf cultivars of L. perenne, forage cultivars of L. multiflorum and annual L. temulentum genotypes. The collection was also enriched with wild L. perenne populations. The tillering phenotype is investigated based on total tiller number, tiller orders, regrowth capacity after cutting, plant height and diameter. All of these traits showed great heterogeneity between and within accessions. As expected, turf grasses had the most tillers and L. temulentum the least. Regrowth after cutting was not linked to the general tillering capacity of an accession, suggesting that different genetic mechanisms control tillering and re-growth. These results, which are based on the evaluation of individual plants, provide a first set of observations for understanding tillering behavior in Lolium.
