WL 303
1. Eight progeny tested clones from Atlantic (6) and Vernal (2) with rapid recovery and good winter survival were combined into a synthetic in 1961 for evaluation and increase.
2. From Nebraska to Maryland and north to St. Paul, Minnesota, WL 303 has been tested generally with good results. It has been the top yielder in many tests. Is used for hay and/or green chop.
3. Flower color - 12% dark purple, 35% moderate-light purple, 40% blue-variegated, 12% purple tinged white to white and 1% yellow, and cream. As an average of foul Midwest locations, late October-November, height was 8.64 inches vs. 5.39 inches for Vernal and 10.15 inches for Flamande. Slightly more dormant than Flamande. Distinctive viney type of growth habit in early spring with nodding terminals at harvest. Otherwise, generally upright in habit.
4. Breeder seed is produced from intercrossing the eight parent clones under isolated field conditions, with honeybees the predominant pollinators. Seed is bulk harvested. Foundation seed is produced from breeder seed between 37 and 44 parallels. Certified seed will be produced only from foundation or breeder seed.
5. 1968 or 1969.
