A behavioural test was applied to highlight the phenologic stages and the notation of some agronomic features of three local fodder grasses, Lolium multiflorum Lamk, Festuca arundinacea Schreb and Phalaris arundinacea L. The results obtained show that generally, the three species present higher germinating ability in laboratory conditions, and good germination (greater than 70 per cent) in the soil. With regard to the phenologic stages, it was noted that the ryegrass and the tall fescue had similar chronological evolution. The red canary grass cycle was different. Otherwise, the notation of agronomic characters showed that in the shooting stage, ryegrass was vulnerable to lodging; tall fescue was less vigorous during winter, especially in the first year of sowing. The following years, the tall fescue reacted better to cold weather conditions, dryness and floods. The red canary grass was slightly sensitive to rust and oidium diseases. As a whole, these ecotypes seem to have quite good general rusticity
