1. Amador is intermediate in dormancy between Lahontan and Moapa 69. It was developed by selecting 110 plants for resistance to Phytophthora root rot from approximately 2,000 seedlings of the USDA germplasm release MnPD₁ following inoculation with pure cultures of Phytophthora magasperma.

2. Amador will be marketed primarily in the Central Valley of California where it has been tested for forage and seed yield. It will be used for hay, grazing and dehydration.

3. Amador has resistance to Phytophthora root rot and the spotted alfalfa aphid. It has not been adequately tested to determine its reaction to anthracnose, bacterial wilt, stem nematode and pea aphid.

4. Seed stocks will be maintained by Northrup, King and Co. and seed will be produced on a three generation basis with breeder, foundation and certified classes. Breeder seed (Syn 2) was produced under isolation near Woodland, California in 1975. This seed is sufficient to last the life of the variety. Certified seed may be produced from foundation or breeder seed.

5. Certified seed will be available in 1975--76.

6. Application for protection under the Plant Variety Protection Act is not planned.

ATLAS

1. Atlas was developed using 3 cycles of recurrent selection for anthracnose resistance followed by one cycle of selection for bacterial wilt resistance. Of the 1407 parent clones about half trace to northern hardy types predominately Titan, Vernal, Weevlcheck, and about half to Flemish types predominately Anchor and Saranac. Several selections were also made from other sources including Beltsville 1An4, 2An4, and 3An4.

2. Atlas was tested in Iowa, Indiana, S. Carolina, N. Carolina, Kansas, Texas, Missouri, Illinois, Louisiana and Virginia. It is adapted to the north central and middle Atlantic states. It is intended to be used for hay, green chop and dehydration.

3. Flower colors are varying shades of purple with a few light blue and about 1% cream. Growth habit is upright and moderately uniform. Atlas has resistance to bacterial wilt and moderate resistance to anthracnose. It is susceptible to Phytophthora root rot. Its reaction to the spotted alfalfa aphid, the pea aphid and stem nematode has not been adequately determined.

4. Seed increase is on a limited generation basis with one generation each of breeder, foundation and certified classes. Breeder seed was produced by interpollinating the parent selections in the greenhouse. No restriction on the area of production of foundation or certified seed.

5. Certified seed will be available in Spring, 1977.

6. Plant Variety Protection has been applied for.

BAKER

1. Baker is a 7--clone synthetic variety of alfalfa. Clones trace to third and fourth cycles of selection within open--pollinated progenies of Nebraska and other alfalfa Conference (C) clones, and to experimental Nebraska (N.S.) synthetics. Parentage includes germplasm from Atlantic, Baltic, Cossack, Grimm, Kansas Common, Ladak, Nebraska Common, Ranger, Turkestan, and Vernal; from Medicago falcata L. and

M. glutinosa M.B. selections and a limited input from P1 numbers 107298, 206278, and 234205. Clonal selection was based on clonal and open--pollinated progeny data for the principal traits.

2. The area of adaptation for forage production is the North Central

states. The anticipated usage is for short -- and long--term hay

production and in rotationally grazed pastures alone and in

combination with grass. Forage yields have been obtained in Illinois,

Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North

Dakota, Oklahoma, and South Dakota.

3. Baker is a winterhardy persistent variety. It has a high level of

resistance to pea aphids, spotted alfalfa aphids, and bacterial wilt.

It has moderate resistance to downy mildew and potato leafhopper

yellowing. It has low anthracnose resistance. It is susceptible to

Phytophthora root rot. Reaction to stem nematode is unknown. Spring

and fall growth habits and rate of recovery after cutting are similar

to Dawson and Vernal.

4. Seed increase shall be three generations; namely, breeder,

foundation, and certified seed classes. Breeder and foundation seed

are the Syn--2 and Syn--3 generations, respectively, grown in the

Northern Region of Adaptation. (Syn--l seed is the bulk harvest from

replicated rooted cuttings of the parental clones grown in isolated

fields or in cages, pollinated by bees). Certified seed may be grown

only from breeder or foundation seed.

5. Certified seed will be offered for sale after the 1977 seed

harvest.

6. Application will be made for Plant Variety Protection under the

certification provision.

CONQUEST

1. Conquest is a twenty-two clone synthetic whose parents trace to ATRA 55, 520, Vernal, Culver and Ranger. The parent clones survived two cycles of spotted alfalfa aphid screening. Selection of clones was next based on high seed production and bacterial wilt resistance.

2. The area of adaptation is the same as that for 520 and Vernal. Conquest has been evaluated in Nebraska, North Dakota, Iowa, Minnesota, Wisconsin, Illinois, Indiana, Michigan, Ohio, New York, and California.

3. Flower color is predominately purple but a few variegated and an occasional yellow and cream flowered plant can be found. Growth habit is semi--erect. Conquest is equal to Vernal in winterhardiness as measured by fall growth. Conquest has resistance to spotted alfalfa aphid, moderate resistance to bacterial wilt, susceptible to Phytophthora root rot and anthracnose. Its reaction to pea aphid and stem nematode is not known.

4. Seed classes for Conquest will be breeder, foundation and certified. Breeder seed is composed of bulk harvested seed from a cage or field isolation of the twenty--two parent clones. Certified seed may be produced only on fields established with breeder and/or foundation seed. No other class or generation is recognized as Conquest.

5. Seed will be first offered for sale in the Spring of 1978.

6. No application for plant variety protection is contemplated.

CUF 101

1. CUF 101 was selected from cultivars growing in a 20- acre,

over--irrigated hay production field which was 2^1/₂ years old and had

been severely infested with the blue alfalfa aphid for about six

weeks. Parent plants were selected from the following cultivars: UC

Cargo (50), UC Salton (I), UC 76 (20), 1972 breeding mixture (18), and

Niagara N71 (2). All parent lines in CUF 101 except Niagara N71 are

related to UC Cargo. Approximately 80% of the germplasm in CUF 101 can

be traced to UC Cargo.

2. The area of adaptation is the low desert valley areas of Southern

California where damage from the blue alfalfa aphid may be severe

and winter production is desired. The primary use will be for hay,

pasture, green chop, and dehydration.

3. Flower color is purple, growth habit is upright, and it is highly nondormant. CUF 101 has resistance to the blue alfalfa aphid, pea aphid, spotted alfalfa aphid, moderate resistance to root rot, and susceptible to bacterial wilt. Its reaction to anthracnose and stem nematode is not known.

4. Breeder seed is bulked seed from 91 parent plants grown in a cage near El Centro, California, during the summer of 1975. Breeder seed will be maintained by the University of California, Davis. Under certification, the classes of seed will be breeder, foundation, and certified. Areas of seed production and maximum eligibility of a stand to produce a given class of seed shall be determined by the certifying

agency in the state where it is certified.

5. Certified seed will first be offered for sale during the fall of 1977.

6. No variety protection is contemplated.
