Gentlemen:

At the time of release of CUF 101 Alfalfa, it was contemplated that the variety would be produced in California in limited amounts for use in the low desert valleys of Southern California where damage from the blue alfalfa aphid has been severe and where winter forage production is desired. As we know, this was not the case, and CUF 101 Alfalfa is now being used in many parts of the world.

Our certification Technical Committee, Department of Agronomy & Range Science, U.C.D. met and discussed the production of CUF 101 out of the area of adaptation. Their action was to amend the release of CUF 101 Alfalfa item VI (National Certified Alfalfa Review Board) "Procedure for maintaining stock seed, seed classes to be used, a statement as to the limitations of generations that may be certified, and any other requirements or limitations necessary to maintain varietal characteristics." as follows:

Breeder seed is bulked seed from 91 parent plants grown in a cage near El Centro, California during the summer of 1975. Under certification the classes of seed will be breeder, foundation and certified. Breeder seed will be used to establish fields of foundation seed. Foundation seed will be used for the production of certified seed. Breeder and Foundation seed will be maintained by the University of California, Foundation Seed Service, Davis. If the supply of breeder seed should become depleted, a lot of foundation seed shall be set aside and used to produce subsequent foundation seed.

Certified seed production for six years is permitted in areas south of the north 40 parallel and below 2,000 feet elevation. Certified seed production is limited to one season for areas above 2,000 feet elevation and in areas north of the north 40 parallel. In these areas seeding must be done in the spring and seed harvested in the fall. No additional certified seed production is allowed in following years.

The committee feels that drastic changes in the composition of CUF 101 Alfalfa would occur if the Certified production field was allowed to grow during a winter.

Sincerely,

Robert B. Ball

Executive Secretary
