A brief description of each variety was prepared in a 6--paragraph format. The information to be included in each paragraph is listed below.
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. 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, leaf, flower characteristics, etc.), physiological characteristics, and other identifying characteristics.
4. A statement relative to its resistance to anthracnose, bacterial wilt, Fusarium wilt, pea aphid, Phytophthora root rot, stem nematode and spotted alfalfa aphid.
NOTE: Because of the heterogenous nature of alfalfa varieties it was determined that it would be most accurate to describe varieties as having high resistance, resistance, moderate resistance, low resistance or susceptibility to a pest; rather than calling the variety 'resistant. The term 'tolerance is to be used only for those situations where the resistance mechanism is concerned with the plants ability to repair, recover or to withstand infestation. Tolerance is not synonymous with low resistance. As a guide to rating resistance levels, the following percentages of resistant plants were used: susceptible=<5%, low resistance=6--14%, moderate resistance=15-- 30%, resistance=31--50%, and high resistance=>51%. When the percentage resistant plants of a variety was considered it was based both on its % resistant plants in a test(s) and its relationship to standard resistant and susceptible checks in that test(s).
5. Procedure for maintaining stock seed, seed classes to be used, a statement as to the limitations of age of stand and generations that may be certified and other requirements or limitations necessary to maintain varietal characteristics.
6. If this variety is accepted by official certifying agencies, when will certified seed first be offered for sale?
7. Will application be made for protection under certifications of the Plant Variety Protection Act?

Germplasm sources were Team, Saranac, Nevada Syn EE, Apalachee, DuPuits, Nevada Syn WW and Dawson, respectively. Selection was from a 3--year--old field planting which had been subjected to stem nematodes and a disease condition later identified as Verticillium wilt. Each of the 7 populations had been subjected to 1 or 3 cycles of recurrent phenotypic selection for stem nematode resistance.
2. Vernema is moderately winter hardy and adapted and intended for use in the Pacific Northwest for hay production. It has been tested near Prosser, Washington for forage yield.
3. Flowers are light purple to purple with less than 10 percent variegated and a trace of yellow.
4. Vernema has resistance to stem nematode and has moderate resistance to Verticillium wilt and bacterial wilt. It has a low resistance to phytophthora root rot. It has not been adequately tested for resistance to pea aphid, Anthracnose or spotted aphid.
5. Sufficient breeder seed (Syn 2) for the expected life of the variety was produced in an isolated field. Certified seed may be produced from either breeder or foundation seed. One generation each of breeder, foundation and certified seed classes is recognized. A maximum of 4 harvest years are permitted on foundation fields and 6 harvest years on certified fields. Foundation seed fields are restricted to the area north of the 40th. parallel. No restrictions are placed on certified seed fields.
6. Certified seed will be available in the spring of 1983.
7. Application for protection under Plant Variety Protection will not be made.
