WL 214
1. After screening for spotted alfalfa aphid resistance, 82 selected plant progenies from Atlantic, Vernal, Ranger, Neb. -67-2813, Grimm and seven Plant Introductions were inoculated with bacterial wilt. Plants showing severe damage by spotted alfalfa aphid, bacterial wilt, Fusarium, mildew or pea aphids, or that set very little seed, were discarded. From 1 to 14 plants (total of 244) from each of 49 progenies were bulk harvested as 62 WB. Of the 244 plants comprising 62 WB, the maternal parents of 29 were derived from Atlantic, 140 from Venal, 49 from Ranger, 4 from P.I. 226,518, 4 from P.I. 215,595, 7 from P.I. 228,287, 6 from P.I. 183,262, 3 from Nebr.67-2813 and 2 from Grimm.
2. Primarily for hay or green chop in the upper Midwest where three or four harvests are to be made.
3. Predominately purple flowers (98%) and 2% white. More uniform than Vernal; less uniform than most Flemish varieties. Upright growth habit.
4. About 40 pounds of the original 62 WB are held in controlled storage as breeder seed for producing foundation seed. Foundation seed will be grown north of the Idaho-Nevada line, in the Pacific Northwest. Certified seed, only from breeder or foundation seed, may be produced in any part of the United States. No other increase or class of seed may be certified.
5. 1968-69.
