In the present study, we examined forage yield and quality features of annual ryegrass (Lolium multiflorum Lam.) lines
developed by using half-sib family selection breeding method. The study was conducted in a randomized complete block
design with three replications between 2009 and 2011 years in Samsun, Turkey. Based on the average of the results of
two years, significant differences were found for all parameters. In the studied lines and varieties, dry matter yields were
found between 6.66 and 9.37 t ha-1, crude protein contents 11.46-13.81%, crude protein yields 0.80-1.18 t ha-1, acid
detergent fiber 31.41-34.75%, neutral detergent fiber 48.77-52.80%, total digestible nutrient contents 56.49-60.80%,
total digestible nutrient yields 376.35-556.42 t ha-1 and relative feed values 109.33-122.83. Annual ryegrass lines 4, 5, 6,
10 and 11 were selected for further regional yield assessments due to their superior yield and quality attributes.
