1. Epredor was developed by three cycles of intercrossing and selection for persistence, wilt resistance, vigor and with special attention directed toward the development of root proliferation (creeping) in a high percent of the population. Original parentage traces to four clones from the variety Travois, and one from Rambler, one from Vernal, and one from PI 183262.

3. Flower color is highly variegated. Growth habit is prostrate to semi--prostrate with wide, low set crowns. Epredor exhibits early fall dormancy, is resistant to bacterial wilt, with a percentage of the plants possessing the ability to spread by creeping roots or rhizomes under space planted conditions.

POLAR I

1. Polar I is a nine clone synthetic with parent clones derived from the cultivars Meeker Baltic, Lahontan, Vernal, Narragansett, Ladak and Cardinal. Parent clones were among plants selected from 1958 through 1964 on the basis of persistence, tolerance to leaf hopper yellowing, bacterial wilt resistance and freedom from foliar diseases. A population of 51 clones was further reduced to the nine parent clones on the basis of polycross progeny performance in replicated trials from 1965 through 1968.

2. The primary use is for hay, haylage and green chop with the probable area of adaptation being the Midwestern United States and Southern Canada. Polar I has been tested in Iowa, Minnesota, Nebraska, and Ohio and currently is in test in Wisconsin and Canada.

3. Flower color is predominantly medium to medium dark purple with an occasional variegated plant and very rarely a cream or yellow flowered plant. Growth habit is semi--erect. Fall dormancy is intermediate, between Vernal and Thor. Polar I is resistant to bacterial wilt and has a low level of resistance to Phytophthora root rot.

4. Seed classes will be Breeders--Foundation--Certified with Breeder and Foundation seed production in the state of Washington.

1. WL 311 was developed from advanced breeding material of diverse background resistant to the spotted alfalfa aphid. Following severe natural anthracnose epiphytotics at Fulton, Maryland in 1966, 1967, and 1968 approximately 300 plant selections were combined into 25 test synthetics. Parent plant numbers ranged from 7 to 32. From the 1969 seed harvests, 400 seedlings of each synthetic were inoculated in the greenhouse with anthracnose. Surviving seedlings were planted in three large cages at Bakersfield, Ca. for seed production in 1970. Following preliminary testing for bacterial wilt, anthracnose resistance and spotted aphid resistance, cage 70 T3 comprised of 308 surviving seedlings from 12 of the test synthetics and the variety WL 215, was chosen for seed increase and released as WL 311.

3. The flowers are approximately 80% purple, 15% blue and blue variegated, 4% white or cream and 1% yellow. WL 311 is resistant to anthracnose, bacterial wilt and the spotted alfalfa aphid. It is moderately resistant to the pea aphid. The growth habit is upright.

5. Certified seed is available in 1975.

6. PVP not contemplated.

WL 318

1. WL 318 was developed for Phytophthora resistance by screening over 100 WL varieties and experimentals that possessed good levels of resistance to pea and spotted aphids. Approximately 3000 seedlings of each entry were exposed to Phytophthora infection and survivors re--exposed in lined tanks in the greenhouse. Selections from 10 different experimental synthetics totaled 89. These are the parents of WL 318.

2. WL 318 is a hay and haylage variety adapted to Phytophthora infested soils in the central region of alfalfa adaptation.

3. The flower color is predominantly purple, blue and blue variegated with about 1% yellow, green and white. In addition to good levels of resistance to bacterial wilt and Phytophthora, WL 318 is resistant to both the pea and spotted aphids.

4. Breeder seed is the initial increase from the 89 parent plants interpollinated with honeybees. Foundation seed may be produced only from breeder seed in eligible fields between the 37 and 44 parallels. Certified seed will be produced only from breeder or foundation seed. No other class or generation of seed will be recognized.

5. Certified seed will be available in 1975.

6. PVP not contemplated.

1. Valor is a northern hardy synthetic variety of 9 clones stemming from Vernal, Scout, Dawson, and Narragansett. Parental clones were selected for recombination following progeny tests in Iowa, Minnesota, and Idaho for agronomic traits, hardiness, disease, and insect resistance.

2. Valor is adapted to the northern alfalfa region (Vernal territory) of the USA for all purpose forage use. It has been tested in Iowa, Minnesota, Wisconsin, South Dakota, Nebraska, Illinois, Idaho, and neighboring areas.

3. Flower color is mostly bluish to purple with some variegation. A winter dormant variety with upright growth habit, moderately fine stems and good late summer and fall regrowth. Valor has good resistance to bacterial wilt and pea aphids, some resistance to anthracnose, and tolerance to leaf hoppers.

4. Breeders seed was produced in an isolated block of about 200 replicated cuttings per clone in Idaho using leaf cutter bees. Seed increase is on the limited basis of one generation each of breeders, foundation and certified, with production of foundation seed in Washington, Idaho, or Oregon. Certified seed will be the first generation increase from breeders or foundation seed only.

5. Winter 1974--75.

DESERET

1. Kayseri alfalfa was developed by two generations of phenotypic recurrent selection for stem nematode resistance in an introduction from Turkey (P.I. 279958). Approximately 150 resistant plants were selected each generation and interpollinated by leaf cutter bees in a cage.

2. The variety was developed for the irrigated valleys of Utah and similar areas where stem nematodes and bacterial wilt are problems. It is expected to replace Lahontan in Central and Northern Utah.

3. Flower color is purple with a large range in color intensity from nearly white to dark purple. Other characteristics include resistance to bacterial wilt, stem nematodes, and lodging. Deseret alfalfa is tall and erect with a growth habit and yield similar to DuPuits, but with less saponin.

4. Seed increase shall be limited to the Breeder, Foundation, Registered and Certified classes. The production of Foundation and Registered seed shall be restricted to Idaho, Oregon, and Washington, and the Northern one-half of Utah and Nevada.

5. Certified seed will be available in 1976 probably.

6. Protection under the Plant Variety Protection Act is being considered.

Lew

1. Lew is a 100--clone synthetic alfalfa cultivar. These parent clones trace their origin to 'African' and 'Indian' sources. Its major attributes are (a) high level of resistance to the stem nematode found in the Salt River Valley of Arizona, and (b) its adaptation to the low desert valley areas of southern Arizona. The parent clones were selected from Polycross Progeny test plots and farmers' fields in southern Arizona having high natural populations of stem nematode. Lew has slightly more resistance to Biotype H of the Spotted Alfalfa aphid than Hayden and Sonora--70. It has considerably more resistance to the stem nematode than Hayden or Sonora--70.

2. Lew is adapted to the low desert valley areas of southern Arizona where stem nematodes are a problem. It is suitable for grazing, green chop, hay, or haylage.

3. Flower color ranges from light to dark purple. It has slightly greater average vegetative growth in early spring than Hayden and Mesa--Sirsa when stem nematodes are present. Lew exhibits little or no evidence of damage when grown on soil heavily infested with stem nematodes.

4. Breeders seed was produced in 1973 and 1974 in an isolated block on the University of Arizona Yuma Branch Station. Foundation seed will be produced from Breeders seed and Certified seed will be produced from either Breeders or Foundation seed.

5. Fall of 1976.

Revision in the generations of seed increase for Tempo (approved by the NCAVRB in 1969) from two generations to three generations. Modified as follows:

The parent clones will be maintained by Farmers Forage Research at Lafayette, Indiana. Breeders seed will be produced in two locations with two parent clones each. Seed from these two locations will be mixed in equal proportions to establish either Foundation or Certified seed fields. There will be three (3) classes of seed: Breeders, produced on parent clones; Foundation, produced from Breeders seed; and Certified, grown from Breeders or Foundation seed. All three classes may be grown in western seed producing areas.

WEEVLCHECK

Revision in the procedure of maintaining seed increase of Weevlcheck (approved by the NCAVRB in 1970) Tlith the removal of greenhouse requirement for bteeders~seed.Revision as follows:

"Foundation seed fields will be grown from Breeders seed." Change in procedure eliminates the requirement that Foundation Seed can only be grown from Greenhouse produced Breeders seed.
