AGATE
AND PLANT SCIENCE RESEARCH DIVISION - ARS, USDA
1. Agate resulted from field screening winter-hardy, wilt resistant varieties for Phytophthora root rot resistance at St. Paul,
Minnesota. In 1960, 25 "resistant" plants from experimental designation Minn. Syn 1 (now designated as the variety Ramsey) and Vernal type background were intercrossed. The polycross progeny were evaluated in 1969 for Phvtophthora resistance in the field and rechecked in the greenhouse. Approximately 10 -- 12 of the most resistant plants were selected from each of the 14 most resistant polycross lines and recombined to produce MnP-A2 (Syn. 1). Eight of the 14 lines traced to Ramsey parentage and six traced to Vernal type parentage. MnP-A2 (Syn. 2) resulted from a Cage increase produced at Caldwell, Idaho by NC-83. MnP-A2 (Syn. 3) was produced at Prosser, Washington and is now classed as Breeder seed.
2. Agate is designed as a special purpose alfalfa variety to be used
on wet soils when Phytophthora root rot is a problem. The area of
adaptation is similar to Vernal and was especially developed for Minnesota but should perform well on wet soils in Wisconsin and parts of Iowa, Nebraska and North and South Dakota. Intended for use as a hay type variety.
3. Agate is very winter-hardy with upright growth habit, dormancy
similar to Vernal. It has higher levels of Phvtophthora resistance
and bacterial wilt resistance than other varieties compared with it
in Minnesota (Iroquois. Narragansett, Ranger, Saranac and Vernal).
It has low levels of resistance to Leptosphaeria leaf spot and
anthracnose and is susceptible to spring blackstem. It has a low
level of resistance to pea aphid and potato leafhopper yellowing,
susceptible to spotted aphid.
4. Agate shall be in the limited generation sequence with one
generation each of Breeder, Foundation and Certified seed classes.
Certified seed shall be the first generation increase of Breeder or
Foundation seed.
Breeder seed was produced at Prosser, Washington. A reserve of Breeder seed will be kept in cold storage at St. Paul, Minnesota. Area of adaptation for seed production is the Northern Region.
5. 1974.
6. No.
CHIMO
L. TEWELES SEED COMPANY
CLINTON, WISCONSIN
1. Germ plasm traces to Cayuga, Vernal and Saranac, Seventy-six
parent clones were selected from Cayuga and three parent clones
were selected from Vernal to provide the genetic population Source A. Fifty parent clones were selected from Saranac to form the genetic population Source B. Breeder seed consists of S1 seed of the Cayuga and Vernal crown in isolation plot (Source A) and the S1 seed of the Saranac lines grown in isolation plot (Source B). Foundation seed is the S2 generation increase of Source A and Source B each produced in isolation. Certified seed is the S1 generation of a blend of the Source A and Source B Foundation seed produced under free pollination between the two genetic populations A and B.
Source A and B clone lines were selected for survival in Wisconsin for seed set and forage yields.
2. This variety has been tested in Wisconsin, Nebraska, Indiana,
Illinois, Michigan, Minnesota, South Dakota and Canada.
Area of adaptations are Northcentral States and Canada.
3. Flower color highly variable from purple to yellow, mainly in the
purple to blue class. Uniformity highly variable showing both
Flemish and hardy types with hybrids between the sources. More dormant than Flemish but less dormant than Vernal. Mostly upright with some plants showing exceptional height. Wilt resistant, moderately resistant to leaf spotting disease, susceptible to leafhopper yellowing.
4. There will be three classes of seed.
Breeder seed Source A and Source B each produced in isolation.
Foundation seed Source A and Source B each produced in isolation.
Certified seed the Syn. 1 increase of a blend of Source A and Source B Foundation seed.
Area of intended seed production Pacific and Pacific Northwestern States.
5. Not designated.
RAMSEY
MINNESOTA AGRICULTURAL EXPERIMENT STATION
AND PLANT SCIENCE RESEARCH DIVISION- ARS, USDA
1. Four clones constitute the parentage of Ramsey. Minn. 589 was selected at Minnesota from a cross of C-10 (Nebraska) x Ind. 73 (Indiana), Minn. 1166 and Minn. 1172 were selected at Minnesota and trace to Ladack germplasm, and C-318 (Pa. 53-13) was selected at the United States Pasture Research Laboratory, University Park, Pennsylvania.
Breeder seed was produced at Lamberton, Minnesota from plants representing equal numbers of the six possible single crosses of the four parent clones.
2. This is a long-lived hay type alfalfa for use on moderately well drained soils. Area of intended usage is Minnesota, Wisconsin, Nebraska, North and South Dakota and parts of Iowa. Its winter-hardiness and high level of multiple pest resistance makes for intended use for long term stands, through five years or longer. It is relatively susceptible (similar to Vernal) to anthracnose; and therefore, it should not be used in the Southern Cornbelt area where this disease can be a problem.
3. The flower color is nearly all purple, full dormancy similar to Vernal, upright growth habit, very winter-hardy with higher levels of resistance to spring black stem and common leaf spot than other varieties with which it has been compared in Minnesota trials (about 100 other varieties included in the test.) It also has moderate to high levels of resistance to downy mildew, Leptosphaeria leaf spot, bacterial wilt, crown rot, potato leafhopper yellowing and lodging.
4. Ramsey shall be in the limited generation sequence with one generation each of Breeder, Foundation and Certified classes. Certified seed is the first generation increase from Breeder or Foundation seed. Area of adaptation for seed production is defined as the Northern Region.
5. Spring 1975.
6. No.
G-777
NORTHRUP, KING AND COMPANY
MINNEAPOLIS, MINNESOTA
1. Germplasm used in the development of G-777 traces directly to Cardinal. The recurrent parentages Cardinal with plants selected on the basis of tolerance to leafhopper yellowing and persistence under field conditions. The nonrecurrent parents were two S1 clones resistant to bacterial wilt selected from Cardinal in the bacterial wilt nursery. The two S1 clones were crossed to 50 Cardinal selections. This cross was evaluated in wilt trials and 55 plants selected and crossed to 34 Cardinal selections. This cross was evaluated and 133 plants selected for resistance to bacterial wilt and desirable agronomic characteristics. One hundred and fifteen plants were further selected from the 133 plants, intercrossed and the seed bulked. Increase of this intercross is the source of Breeder seed.
2. G-777 is considered primarily for use in hay production and was adapted to areas where Cardinal and other Flemish type alfalfas have performed satisfactorily. Area in which tested consist of Illinois, Iowa, Minnesota and Ohio.
3. Flower color predominantly purple to dark purple with remaining plants lighter purple to blue. Foliage is dark green with erect growth habit and moderately resistant to bacterial wilt.
4. G-777 shall be in the limited generation sequence with one generation each of Breeder, Foundation and Certified seed. Certified seed shall be the first generation increase if Breeder or Foundation seed. The production of Foundation seed will be limited to the States of Washington, Idaho, Utah and Northern Nevada.
5. 1973.
WL -309
1. One additional cycle of screening for both pea and spotted
alfalfa aphid was made from the populations going into WL 309. Seven
plant selections were made and increased under 67 Cage J. Ten
selections were increased as 67 Cage G. Three clones were common to
both 67 Cage J and 67 Cage G. Tested separately the two were later
combined because of similar performance and background to comprise
the variety.
2. The intended use is primarily for hay production principally in
the Central Region of alfalfa production and some Northern Region
areas where spotted alfalfa aphid resistance is needed. Has been
tested in Nebraska, Iowa, Ohio, Missouri with additional tests in
adjacent areas.
3. Flower color is approximately 40 percent purple, 20 percent blue
and 40 percent variegated with a trace of yellow and white. Growth habit upright. Moderately resistant to both the pea aphid and the spotted alfalfa aphid (biotypes present in Kern County, California with the possible exception of ENTF.)
4. Breeder seed is a combination of 67 Cage J and 67 Cage G produced under Cage isolation with honeybees used as pollinators. Foundation seed is produced in fields planted with Breeder seed between the 37 and 44 parallels.
WL 309 shall be in the limited generation sequence with one generation each of Breeder, Foundation and Certified classes. Certified seed shall be the first generation increase from Breeder or Foundation seed.
5. 1972-1973.
6. No.
WL 450
1. Seedling inoculation with stem nematode commenced in late 1964 using selected clones from WL 504, Flemish varieties and PI 141462 for progeny testing. Six thousand seedlings were screened which resulted in 708 tolerant or resistant plants of which 1% traces to PI 141462, 2.4% to Flemish and 96.6% to WL 504. Twenty resistant survivors selected for type and disease resistance were crossed with selected plants related to WL 504 in an isolated nursery. Seed was harvested from each of the stem nematode resistant plants and 500 seedling of each plant were reinoculated. About 400 selected survivors were planted in an isolated cage for observation, rogueing and seed production. Thirty-one clones showing 35% or more stem nematode resistance in progeny testing were recombined in 1967 to develop WL 450.
2. WL 450 is adapted to portions of the Southwest and other related
areas where stem nematode is a problem. It has been tested in
California, Arizona, Minnesota, Southern Nevada, Southern Utah and
North Carolina. It is intended for hay, silage and dehydration.
3. Flower color is predominately purple to light purple, growth
habit upright and moderately uniform, resistant to spotted alfalfa
aphid of unknown local biotypes of Kern County, California and downy
mildew, moderately resistant to the pea aphid and tolerant to
Southern anthracnose and Leptosphaeria leaf spot.
4. Breeder seed is the Syn. 2 of the 31 clones selected for 35% or
more stem nematode resistance. The Syn. 1 seed was planted in Kern
County, California producing 284 pounds of Breeder seed which is
maintained in temperature and humidity controlled storage. WL 450
shall be in the limited generation sequence with one generation each
of Breeder, Foundation and Certified seed classes. Certified seed
shall be the first generation increase of Breeder or Foundation
seed.
5. 1973-1974.
6. No.
WL 451
1. Mass selection was practiced on nearly 300,000 plants in 1964,
most of which had been tested for stand longevity at Bakersfield,
California. The ultimate 1006 plants selected had been screened for
spotted alfalfa aphid and/or pea aphid resistance and for root
rotting organisms common to the area. Six hundred plants trace to
Lahontan or Lahontan crossed, 356 plants to generations preceding WL
504. Six each of five clones showing longevity at Piper City,
Illinois and 20 spotted and pea aphid resistant plants of N 529 were
allowed to interpollinate in isolation to produce Breeder seed.
2. WL 451 is adapted to portions of the Southwestern United States
similar to the Northern San Joaquin and Sacramento Valleys requiring
varieties more dormant than Moapa but less dormant than Lahontan. It
has been tested in Arizona, California, Southern Nevada and Southern
Utah. Its intended usage is for hay, silage and dehydration.
3. Flower color is predominately purple to light purple, 2% of the
flowers white to slightly variegated, moderately uniform and upright
in growth habit, moderately resistant to bacterial wilt, tolerant to
downy mildew and pea aphid, resistant to unknown local biotypes of
the spotted alfalfa aphid present in the Kern County, California
area.
4. Breeder seed was produced by the interpollination of the selected
clones as set forth in No. 1 above. Seed increase shall be in the
limited generation sequence with one generation each of Breeder,
Foundation, and Certified seed classes. Certified seed shall be the
first generation increase of Breeder or Foundation seed.
Foundation and Certified seed classes are limited to the San Joaquin Valley of California or similar areas.
5. 1973-1974.
6. No.
WL5O1--R
1. WL5Ol-R was developed through mass selection of a population
originally consisting of over 425,000 plants beginning in 1964
at Bakersfield, California. Selection was based on longevity, type, spotted alfalfa aphid resistance, freedom from foliage disease and root rotting organisms common to the area. The final population consisted of 1024 plants of which 250 plants were from Lahontan and Lahontan crosses, 155 plants from Sonora, 441 plants from preceding and advanced generations of WL504, 62 plants from N529 selfing and crosses and 116 plants tracing to nondormant, aphid resistant selections and/or crosses from Atlantic, Vernal and Saranac. These plants were planted at random in isolation and cross-pollinated to produce Breeder seed.
2. WL5O1-R is adapted to the Southwestern United States and has been
tested in California, Arizona, Southern Utah, Southern Nevada.
Southern New Mexico and Western Kansas. Its intended usage is for hay, silage and dehydration.
3. Flower color is predominately purple to light purple, moderately
uniform in growth with about 5% of the plants being slightly more
nondormant than the balance of the population in the winter months, resistant to the unknown local biotypes of the spotted alfalfa aphid in Kern County of California, moderately resistant to the pea aphid and tolerant to downy mildew, southern anthracnose and bacterial wilt.
4. Seed increase shall be in the limited generation sequence of one
generation each of Breeder, Foundation and Certified seed classes.
Certified seed shall be the first generation increase of either Breeder or Foundation seed. Foundation seed is produced from Breeder seed in the San Joaquin Valley of California.
5. 1973--1974.
6. No.
WL 600
1. In 1968, 18 superior clones demonstrating excellent vigor, type
and resistance to pea and spotted alfalfa aphid and leaf disease
were selected from the phenotype recurrent selection program which was used to develop WL504 and WL508. Beginning in 1965 a nondormant selection from WL209 (a dormant variety was outcrossed for two generations) each generation with selected different and unrelated nondormant clones. Following severe pea aphid and spotted alfalfa aphid screening and selection for downy mildew resistance, 14 clones were selected to be cross pollinated with the aforementioned 19 clones under isolation to produce Breeder seed.
2. WL600 is adapted to the Southwestern United States where most
nondormant alfalfas can be grown, Intended usage is for hay,
silage and dehydration. It has been tested in California and Arizona.
3. Flower color purple, moderately uniform and upright in growth
habit and nondormant. Resistant to the unknown local biotype of the
spotted alfalfa aphid in Kern County of California, resistant to pea aphid, moderately resistant to downy mildew and tolerant to southern anthracnose. Special marker on frequent auxiliary branching.
4. Breeder seed is the Syn. 1 increase from 32 clones planted in
isolation in Kern County, California. Foundation seed will be
produced in the San Joaquin Valley of California. The variety shall be in the limited generation sequence of one generation each of Breeder, Foundation and Certified seed classes. Certified seed shall be the first generation increase from Breeder or Foundation seed.
5. 1973 or 1974.
6. No.
530
1. 530 is composed of 24 clones from the backcross program and nine
clones from Saranac. The backcross program was from bacterial wilt
resistant selections from Vernal crossed with outstanding plants of Flemish type. Progeny of the crosses were screened for wilt resistance and those with resistance backcrossed to the Flemish type. Progeny were screened for bacterial wilt resistance and selections put into isolation for seed production. The variety Saranac was also screened for spotted aphid resistance, combined into isolation and further screened for spotted aphid resistance.
2. 530 has been evaluated in Kansas, Iowa, Minnesota, Wisconsin, Illinois, Ohio, Nebraska, Michigan, North Dakota and other Northeastern States. Its intended usage is for hay, haylage, dehydration or grazing in the Northern Region and most of the Central Region.
3. Flower color from dark purple through light purple and an
occasional plant with variegated flowers. Some variability in height
during the entire growing season. Good persistence with more full
dormancy than DuPuits and less full dormancy than Ranger and Vernal.
Uniformly dark green when compared to Vernal. Resistant to bacterial
wilt and good resistance to the spotted alfalfa aphid complex of the
Five Points area of California. Has a high level of resistance to
Leptosphaerulina moderate resistance to downy mildew and pea aphid
tolerant.
4. Breeder seed is composed of seed produced from isolation planting
from bulk harvested polycross seed from a cage increase of the 33
parent clones.
530 shall be in the limited generation sequence with one generation each of Breeder, Foundation and Certified classes. Certified seed shall be the first generation increase from Breeder or Foundation seed. No restrictions on area or seed production.
