Narrative
Averaged 102.4% in seven tests in 3 production years and four tests for one production year (about 3% higher than average, which is as good as any well-tested cultivar from public or private breeding program). Standard pest resistance tests indicate high resistance to bacterial wilt, and the spotted alfalfa aphid. Moderate resistance to phytophthora root rot and low resistance to anthracnose and the blue alfalfa aphid. Fall dormancy is approx. 4.6 compared to Saranac = 4 and Archer = 5 (1 to 9 scale, where 9 is very non dormant). Flower color about 95% purple and 5% variegated.
