Breeding materials need to be evaluated in both the area of seed production and the area of forage production. Breeding programs often space-plant seeds. The resulting plant may perform differently than it would if seed were broadcast or drilled. Performance needs to be evaluated when the cultivar is grown in a mixed plant community. New cultivar development is limited because profitability is low.
Cultivars tend to be adapted to relatively small areas which limits potential sales.
