Abstract
Improvement of N use efficiency of timothy (Phleum pratense L.) involves higher DM yield but, for feeding purposes, N concentration should also be considered. Differences in N use efficiency were found among 40 genotypes of timothy. The analysis of residues of the linear regression between N uptake and DM yield of all genotypes allowed for the selection of genotypes with both high N use efficiency and contrasted N concentrations. Key words: Phleum pratense L., timothy, genetic selection, nitrogen use efficiency
