Titan
1. An 11-clone, limited generation, synthetic variety. Parent clones isolated from 55 selections made in 4-year-old, decimated, Vernal source nursery in 1963 and evaluated in extensive clonal, S1, polycross and single cross tests from 1963-67 in Midwest and Pacific Northwest for insect and disease resistance, seed and forage traits, and combining ability.
2. Evaluated in Kansas, Nebraska, South Dakota, Minnesota, Iowa, Illinois, Wisconsin, Indiana, Oregon, Idaho, Ontario and Quebec. Adapted to North Central Region, Pacific Northwest, Southern Canada, and Northeastern States where Vernal ss used and good hardiness and bacterial wilt resistance desired. Suited for all purpose forage use in short and long term stands.
3. Flower color - ranges from purple, blue, variegated to yellow and white. Variegated percentage is greatest with purples intermediate, and yellow and white a small percentage. Winter dormant, somewhat more vigorous, taller and erect in late summer and fall than Vernal. Moderately fine stems - similar to Vernal, blooms several days earlier. Moderately tolerant to leafhopper yellowing, high Level of bacterial wilt resistance, some tolerance to pea aphid.
4. Breeder seed produced in 1967 in isolated, replicated block of about 1,000 cuttings of each parental clone near Caldwell, Idaho, using heavy load of leafcutter bees. Foundation seed production fields planted only in Pacific Northwest with breeder seed and inspected by Idaho and Washington Crop Improvement Associations. Commercial or certified seed production fields planted with breeder or foundation seed only. Seed produced on fields not planted with breeder or certified foundation seed will not be recognized as Titan by the Rudy-Patrick Seed Division of W. R. Grace and Company.
