WL 210
1. Ten clones derived from Vernal or Vernal crosses (8), Narragansett (1) and Culver (1) were selected for dark green color, forage yield and seed yield at the conclusion of a 2-year seed yield trial conducted at Bakersfield, California. Using PX seed, a test lot of PX 210 was planted in 1963 and tested under that designation. Subsequent lots of 63 and 64 Ca.E (Syn.l) as well as a seeded increase of 63 Ca.E have been tested.
2. Adapted to same areas as Vernal and WL 202 for hay, silage or green chop.
3. Flower color - 4% dark purple, 55% medium-light purple, 35% variegated, 4% white and 2% yellow. Average fall height at four Midwest locations was 7.35 inches for WL 210, 6.38 inches for WL 202 and 5.39 inches for Vernal. Growth habit is similar to Vernal and WL 202. Dark green color when compared with older standard varieties. Has scored 3.8 in spotted alfalfa aphid resistance compared with 2.0 for Lahontan and 4.8 for Saranac where 1 = no damage, 3 = moderate damage with many surviving seedlings and 5 = susceptible with few surviving plants.
4. Breeder seed is Syn. 1 seed from bulk harvested parent clones. Foundation seed is grown in the northern region of adaptation from breeder seed. Certified seed will be grown only from breeder or foundation seed.
5. 1968 or 1969.
