Information pertinent to certifying agencies which was requested on the application for each variety and the information submitted by the applicants are given below. The respective applicants should be contacted if additional information is desired.

Some of the Information Requested from Applicant:

1. A statement of the origin and the breeding procedures used in developing the variety.

2. Area of probable adaptation and primary purpose (hay, grazing, etc.) for which this variety will be used. Report States and areas within States where the variety has been tested, and proposed areas of recommendation and merchandising.

3. Information of value to field inspectors (such as uniformity, 1eaf, flower characteristics, etc.), physiological characteristics, obvious disease and insect reactions, and other identifying characteristics.

4. 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.

5. If this variety is accepted by official certifying agencies, when will certified seed first be offered for sa1e?

Information Submitted by Applicant on the Above Points:

Apex

1. Thousands of plants of Flemish origin screened for bacterial wilt resistance in greenhouse. Clones showing evidence of resistance were further evaluated for wilt and pea aphid resistance, hardiness, Flemish vegetative traits, seed productivity, etc, in clonal, S₁ and polycross progeny tests in Iowa, Illinois, Minnesota and Idaho from 1961-1965. Apex is a synthetic of 10 clones selected from this program.

2. Same areas as other Flemish varieties (Central Corn Be1t, Northeastern States, certain Mid-Atlantic areas) northern Idaho, eastern Canada, western Washington and Oregon, southern British Co1umbia, etc_.) for forage use. Best suited for hay, green chop, wilted haylage and dehydration use. Will be merchandised primarily in above or neighboring areas where proven adapted.

3. Predominantly purplish to bluish flowers, reasonably uniform in vegetative traits (growth habit, leaf size, etc.). Fall growth habit similar to Alfa and Du Puits - reasonably good fall vigor. Winter dormancy like Alfa. Upright growing, fast recovering type like Alfa and Du Puits. High level of pea aphid resistance. Resistant to common leafspot. Pod color and shape similar to Alpha - relatively large pods, well curled. Somewhat resistant to bacterial wilt.

4. Will be increased on limited generation basis B Breeders seed (Syn1) from clones, foundation seed (Syn2) from fields established only with breeders seed, certified seed (Syn 2 or 3) from fields established only with breeders or foundation seed. Only Syn 2 and Syn 3 generations may be certified as Apex for merchandising purposes. Breeders seed produced under isolation with 700-1100 replicates of 10 parental clones at Caldwell, Idaho. Foundation seed shall be grown only in Columbia Basin of Washington. Certified seed to be grown primarily in Washington, Oregon and Idaho.

5. 1966.

Arnim

1. Started in 1928 in Central Germany by selecting 3,000 individual plants from the Thuringia land race. First reduced to 300 plants, then 70 and after a period of eight years testing reduced to 20 plants. These 20 elite plants were hybridized with Medicago falcata and Kayserie from which was selected the variety.

2. To be used for hay, haylage, green chop, dehy and grazing in areas where Vernal Ranger, 522, 525, and Narragansett are being used successfully. Tested in Iowa, Indiana, Illinois, Wi
