Apollo II Revision of January 1982 description
APOLLO II
(Revision of the original description)
When presented to the Review Board in December 1931, Apollo II was described as not adequately tested for Spotted Alfalfa Aphid resistance. Additional testing indicates that the variety should be rated as moderately resistant to the Spotted Alfalfa Aphid.
BARON
1. Baron is a 654 plant variety with 50% of the percentage tracing to
29 clones obtained from Dr. Bill Melton. These clones traced to El Unico (9), Mesa Sirsa (3), Mesilla (3) Zia X Turkistan (3), Acco 765 (2), Miller Synthetic (2), WL 504 (2) with one each from WL 501, AT 530, Acco 657, Hayden and Kanza. The other 50% of the parentage traces to WL 318. Source materials were screened from 1 to 4 cycles for resistance to Phytophthora root rot, anthracnose, spotted alfalfa aphid and blue alfalfa aphid.
2. Baron is adapted to the San Joaquin and Sacramento Valleys of
California and high desert valleys of southern California, Arizona,
Nevada and New Mexico for hay, greenchop and dehydration purposes. It
has been tested in California, Arizona and New Mexico.

predominantly purple with some blue variegated. Growth habit is
upright.
4. Baron has a high 1evel of resistance to pea aphid, spotted alfalfa
aphid and blue alfalfa aphid, resistance to Phytophthora root rot and
Fusarium wilt and moderate resistance to anthracnose and bacterial
wilt. Reaction to stem nematode has not been adequately tested.
5. Breeder seed (Syn I) was produced on the parent plants near Nampa,
Idaho, with sufficient seed for the life of the variety held in
controlled storage. One generation each of breeder, foundation, and
certified seed classes is recognized. Certified seed may be produced
from either breeder or foundation seed. A maximum of three and five
years is permitted on stands producing foundation and certified seed,
respectively. Foundation seed production is limited to the southern
region of adaptation.

Fusarium wilt, pea aphid, spotted alfalfa aphid and stem nematode, and
moderate resistance to Verticillium wilt, Phytophthora root rot,
anthracnose and blue alfalfa aphid.

field, California, in 1977. Sufficient foundation seed was produced at
Nampa, Idaho, for the life of the variety. One generation each of
breeder (Syn 1), foundation (Syn 2) and certified (Syn 3) is
recognized. A maximum of 3 harvest years are permitted for stands
producing foundation seed, and 5 harvest years for stands producing
certified seed.

derived from intercrossing 47 clonal selections. The 47 clones trace
to as many experimental cage combinations developed following four or
more cycles of field evaluation and recombination. Each experimental
cage combination had been screened for one or more of the following:
bacterial wilt, Phytophthora root rot, pea aphid and spotted alfalfa
aphid. Source material traces primarily to Vernal, Atlantic, Saranac,
Ranger and Ladak.

7. Plant Variety Protection has been granted. The certification option
was not requested.
PIERCE
1. Pierce was developed by using a combination of phenotypic selection
and line crossing. The final procedure consisted of intercrossing
approximately 500 blue alfalfa aphid resistant selections. Two hundred
selections were taken from each of the experimental line C-78--524 and
C--78--525. The other 100 selections were taken from each of the
experimental line PX--75-61. The three experimental lines were
developed by combining selections for forage yield, blue alfalfa aphid
and Phytophthora root rot resistance from the cultivars CUF 101 (40%),
WL 318 (20%), WL 512 (20%), MSF--6 (3%), Exp 47 (3%), Aphidor (3%),
Lahontan (3%), Caliverde (3%), Moapa (3%), and Sonora (3%).
2. Pierce has been tested for forage yield and persistence in
California and Arizona. It will be used for hay, greenchop, haylage
and grazing in the Southern Region of the US (primarily California and
Arizona).
3. Pierce is similar to Moapa 69 in dormancy. Flower color at full
bloom is approximately 24% dark purple, 47% medium purple and 29%
light purple.
4. Pierce has high resistance to Fusarium wilt and blue alfalfa aphid;
it has resistance to spotted alfalfa aphid, pea aphid, stem nematode
and Phytophthora root rot, it has low resistance to bacterial wilt.
Reaction to anthracnose is unknown.
5. Adequate breeder seed (Syn I) has been produced for the life of the
variety. Seed classes will be breeder, foundation and certified.
Limitation on age of stand for producing breeder, foundation and
certified. Limitation on age of stand for producing breeder, founda-
tion and certified will be one, three and five years, respectively.
6. Certified seed will be available in 1982.
7. Application for plant variety protection is being considered.
CW 940
1. CW 940 is a synthetic variety. The 198 parent plants tract to
disease resistant selections from the varieties Iroquois, Saranac AR,
Apollo, 120, and Olympic and the USDA germplasm release Beltsville
3--An4.
2. CW 940 is a hay and haylage type variety adapted to the northern
and central US and southern Canada. It has been tested in Wisconsin,
Minnesota, South Dakota, Pennsylvania, and Ontario.
3. Fall dormancy is similar to Saranac. Flower color is approximately
75% purple, 24% variegated and 1% yellow or cream.
4. CW 940 is resistant to bacterial wilt, Phytophthora root rot and Fusarium wilt and moderately resistant to anthracnose. It has low resistance to spotted alfalfa aphid. Reaction to the pea aphid and stem nematode has not been determined.
5. Breeder (Syn 1) seed was produced in cage isolation at Woodland,
California, in 1979. Seed increase is on a limited generation basis
with one generation each of breeder and certified seed classes and two
generations of foundation seed class. Breeder (Syn 1), foundation (Syn
2 or 3), and certified classes (Syn 2, 3 or 4) with limitations on age
of stand of 1, 2 and 6 years, respectively, will be maintained for its
projected life in environmentally controlled storage by Cal/West
Seeds.
6. Certified seed will be marketed in the fall of 1983.
7. If application for Plant Variety Protection is made, it would be
under the certification provision of the US Plant Variety Protection
Act.
UC CIBOLA
1. The parent plants of UC Cibola were selected from a 3 year alfalfa
stand growing in a sandy soil infested with four genera of root
nematodes. The field had also been infested with blue alfalfa aphids
prior to selection. Parents are 46, 26, 28 plants, respectively, from
UC Salton, UC 76, and UCPX 1971.
2. The probable area of adaptation will be areas in the Palo
Verde Valley of California (Blythe) infested with root nematodes. It has been tested in the low desert valleys and San Joaquin Valley of California. The primary use will be for hay production.
3. It is nondormant, purple--flowered, and erect in growth habit.
4. It is susceptible to bacterial wilt and has low resistance to the
blue alfalfa aphid, moderate resistance to Phytophthora root rot,
resistance to the pea aphid and the root--knot nematode Meloidogyne
hapla, high resistance to Fusarium wilt and the spotted alfalfa aphid,
and survives well in fields infested with four or more genera of root
nematodes where it is adapted in the Palo Verde Valley of California.
5. Seed classes will be breeders (produced in a cage in 1977 and
1978), foundation and certified. Breeder and foundation seed will be
maintained by the University of California Foundation Seed Project,
Davis. Areas of seed production and maximum eligibility of stand to
produce a given class of seed shall be determined by the certifying
agency in the state where it is certified.
6. Certified seed will be available in 1984.
7. No plant variety protection is contemplated.
