Description
Trials on orchard grass (Dactylis glomerata L.) were conducted on spaced plants in 1992 and 1993 in Lethbridge, Alberta to identify components that could be used for improvement of winterhardiness and seed yields in this species. Results showed that seed yield/plant was significantly higher in Kay than Chinook orchard grass but only in 1992. Seed yields were significantly correlated in each year with visual scoring for forage yield potential, seed yield potential, vegetative height, panicle length and panicle number/plant. Higher yielding plants were taller and had larger numbers of panicles/plant and longer panicles than lower yielding plants. A large amount of variability was found among individual plants of each cultivar in seed yield, indicating possibilities for selection of superior lines.
