1. NAPB 34 is a 36-clone synthetic variety, parent clones were selected following 3-5 cycles of field screening for resistance to Verticillium wilt, from populations which have previously been screened for winter survival and resistance to Phytophthora root rot, antrhacnose, bacterial wilt and Fusarium wilt. Parentage traces to Apollo II (24%), Maverick (15%), Apollo (12%), Endure (9%), Armor (6%), Thunder (6%), and KS-10, Vangard, Trident, Figeva 118, Anchor, WL 318, Deseret, Pacer, Trek, Spredor (2-3% each). Germplasm sources are M. falcata (20%), Ladak (8%), M. varia (18%), Turkistan (14%), Flemish (32%), Chilean (4%), and Peruvian (4%).
2. NAPB 34 is intended for use in the northern region of the U.S. for hay, haylage, greenchop or dehy. It has been tested in Iowa, Illinois, Idaho, and Wisconsin.
3. NAPB is a dormant variety with fall dormancy similar to Ranger. Flower color is approximately 71% purple and 29% variegated with less than 1% cream and yellow.
4. NAPB 34 has high resitance to Phytophthora root rot, Verticillium wilt and Fusarium wilt and resistance to bacterial wilt, anthracnose, and downy mildew. Not tested for resistance to stem nematode, pea aphid, blue alfalfa aphid or spotted alfalfa aphid.
5. Breeder (Syn 2) seed was produced from Syn 1 near Nampa, ID with sufficient quantity for the expected life of the variety held in controlled storage. Two years production was bulked. Seed increased is limited to one generation each of breeder, foundation and certified classes. Certified seed may be produed from breeder or foundation. A 3 and 6 year stand life is permitted on fields producing foundation and certified seed, respectively. Foundation seed production is limited to the northern region of adaptation.
6. Certified seed will be available in 1988.
7. No decision regarding application for Plant Variety Protection has been made.
