1. The selection criteria used in the development of this variety include forage yield, forage quality,
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
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 the North Central and East Central regions. This variety has been tested in
Wisconsin, Indiana, Pennsylvania and Iowa, and is intended for use in the North Central and East
Central regions.
3. Test variety is Moderately Dormant, similar to FD4 check. Test variety is Very Winterhardy, similar
to WS2 check. Flower color (Syn2) is 96% purple, 2% variegated and 2% cream with a trace of
yellow and white. This variety has high multifoliolate leaf expression. Test variety is “Roundup
Ready®” expressing tolerance to Roundup® herbicide conferred by the cp4-epsps transgene.
4. Test variety has high resistance to anthracnose (Race 1), bacterial wilt, Phytophthora root rot,
Verticillium wilt, Fusarium wilt, Aphanomyces root rot (Race 1) and pea aphid; resistance to rootknot
nematode (M. hapla) and stem nematode; with moderate resistance to spotted alfalfa aphid.
Reaction to blue alfalfa aphid has not been tested.
5. Seed increase is on a limited generation basis with one generation each of breeder and foundation and
two generations of certified seed classes. Breeder (Syn 1), foundation (Syn 2), and certified (Syn 2 or
Syn 3) classes will be recognized. Production of Syn 2 foundation seed requires consent of the
breeder. 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. 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.
