Anthesis date is the major factor controlling distribution of forage yield and quality of annual ryegrass (Lolium multiflorum Lam.) in the spring. This study was initiated to evaluate variation and selection response for anthesis date and to measure correlated responses in annual ryegrass. Four annual ryegrass cultivars were evaluated for beading date, anthesis date, spikelets per spike, and florets per spikelet over 3 yr in the field at Mississippi State, MS. Only spikelets per spike and florets per spikelet, showed significant cultivar X year interactions. Differences among cultivars were observed for all four characteristics. Two cycles of
