Performance Of Certified Seed Lots Of Dawson Alfalfa, W. R. Kehr, G. R. Manglitz

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Breeder, foundation, and certified seed lots of Dawson alfalfa, Medicago sativa L., were tested to determine stability in performance during three generations of seed increase under certification. Two field experiments were conducted, a seeded forage yield test and a space-planted test. Greenhouse experiments included separate tests for resistance to pea aphids, spotted alfalfa aphids, and bacterial wilt. Results obtained on certified Dawson alfalfa seed classes in field and greenhouse experiments were in agreement with the original variety description.
