1. The selection criteria used in the development of this variety include Roundup tolerance, forage
yield, winter-active growth, persistence and resistance to one or more of the following pests: bacterial
wilt, Fusarium wilt, Verticillium wilt, anthracnose (Race 1), Phytophthora root rot, and Aphanomyces
root rot (Race 1 and/or Race 2). Parent plants contain tolerance to Roundup® (glyphosate) herbicide
conferred by the CP4 5-enolpyruvylshikimate-3-phosphate synthase (cp4-epsps) transgene, specifically,
the USDA deregulated Roundup Ready® alfalfa transgenic events J101 and/or J163 (OECD unique
identifiers: MON-00101-8 and MON-00163-7, respectively). .
2. This variety is adapted to California and the low desert areas of the West. This variety has been
tested in California. It will be used in the Southwest. .
3. Test variety has fall dormancy similar to FD8 checks. Flower color (Syn2) is 100% purple with a
trace of yellow, white, cream and variegated. Test variety is “Roundup Ready®” expressing tolerance to
Roundup® herbicide conferred by the cp4-epsps transgene. .
4. This variety has high resistance to anthracnose (Race 1), Bacterial wilt, Fusarium wilt,
Phytophthora root rot, pea aphid, spotted alfalfa aphid, root-knot nematode (M. hapla), blue alfalfa aphid
and stem nematode; with moderate resistance to Verticillium wilt. Reaction to Aphanomyces root rot has
not been tested .
5. Seed increase is on a limited generation basis with one generation of breeder and two generations
of foundation and certified seed classes. Breeder (Syn 1), foundation (Syn 2), and certified (Syn 2 or Syn
3) classes will be recognized. Breeder seed was produced in the field near Nampa, ID in 2003. Forage
Genetics will maintain sufficient foundation seed for the projected life of the variety. Production of Syn2
foundation seed requires the consent of the breeder. Stands of foundation and certified seed fields are
limited to 3 and 6 years, respectively. At least one glyphosate application is required during early stand
establishment so that cp4-epsps null segregant plants are removed from the seed field prior to pollination.
(Null segregant plants are the plants that do not contain the Roundup Ready® trait due to normal genetic
segregation in this variety). .
6. Certified seed will be marketed in 2006..
7. No decision has been made concerning Plant Variety Protection Act. .
8. The information in this application may not be forwarded to the PVP office..
