Description
Seven cultivars of perennial ryegrass (Lolium perenne) with (EI) and without (EF) Acremonium endophytes were compared in trial plots at 5 locations in France. Such a trial was also established with 6 tall fescue (Festuca arundinacea) cultivars in 5 locations. These trials were sown either in 1994 or 1995. Yields and visual traits (rust and drought tolerances, vigour 6-weeks following the sowing) were assessed. The data were analysed by means of variance analysis with two main factors (cultivars and endophyte status) and their interaction. As interaction was not significant, some significant differences between EI and EF cultivars were detected. It is worth noticing that either there is no difference between EI and EF cultivars or EI cultivars outperform EF ones and that most significant differences are observed in stressful locations. Such results could lead breeders to question whether endophyte is really useful for forage cultivars used in France. Before answering, it seems useful to wait for some years to see whether effects of endophyte will increase over time or not.
