Information Submitted by Applicant on the Above Points:



Apex



1. Thousands of plants of Flemish origin screened for bacterial wilt resistance in greenhouse. Clones showing evidence of resistance were further evaluated for wilt and pea aphid resistance, hardiness, Flemish vegetative traits, seed productivity, etc, in clonal, S1 and polycross progeny tests in Iowa, Illinois, Minnesota and Idaho from 1961-1965. Apex is a synthetic of 10 clones selected from this program.



2. Same areas as other Flemish varieties (Central Corn Be1t, Northeastern States, certain Mid-Atlantic areas) northern Idaho, eastern Canada, western Washington and Oregon, southern British Co1umbia, etc.) for forage use. Best suited for hay, green chop, wilted haylage and dehydration use. Will be merchandised primarily in above or neighboring areas where proven adapted.

3. Predominantly purplish to bluish flowers, reasonably uniform in vegetative traits (growth habit, leaf size, etc.). Fall growth habit similar to Alfa and Du Puits - reasonably good fall vigor. Winter dormancy like Alfa. Upright growing, fast recovering type like Alfa and Du Puits. High level of pea aphid resistance. Resistant to common leafspot. Pod color and shape similar to Alpha - relatively large pods, well curled. Somewhat resistant to bacterial wilt.



4. Will be increased on limited generation basis B Breeders seed (Syn1) from clones, foundation seed (Syn2) from fields established only with breeders seed, certified seed (Syn 2 or 3) from fields established only with breeders or foundation seed. Only Syn 2 and Syn 3 generations may be certified as Apex for merchandising purposes. Breeders seed produced under isolation with 700-1100 replicates of 10 parental clones at Caldwell, Idaho. Foundation seed shall be grown only in Columbia Basin of Washington. Certified seed to be grown primarily in Washington, Oregon and Idaho.



5. 1966.





Arnim



1. Started in 1928 in Central Germany by selecting 3,000 individual plants from the Thuringia land race. First reduced to 300 plants, then 70 and after a period of eight years testing reduced to 20 plants. These 20 elite plants were hybridized with Medicago falcata and Kayserie from which was selected the variety.



2. To be used for hay, haylage, green chop, dehy and grazing in areas where Vernal Ranger, 522, 525, and Narragansett are being used successfully. Tested in Iowa, Indiana, Illinois, Wisconsin, Minnesota, Michigan and other States.



3. Flower color runs from white over yellow to blue and to violet and a wide range of variegated colors. Mostly glabrous, erect, slightly taller than Vernal or Ranger. See Wisconsin reports for 1961 and 1962 on alfalfa fall and winter dormancy tests. Erect, leafy, lacks wilt resistance.



4. The variety Arnim (Altdeutsche Bastardiuzerna von Arnim) is maintained by the Countess von Arnim under supervision of the German Bundesortenamt. Under this supervision, breeders seed is produced from a vegetatively propagated clonal seed production field in a dry region, APfalz,@ located on the left side of the Rhine. Breeders seed is planted in Germany to produce basic seed. Seed planted in the United States to produce certified seed shall be one of the following: (a) Luzerne von Arnim Basic Seed supplied by Countess von Arnim through the firm of L.C. Nungesser, Darmstadt, Germany; (b) Foundation seed produced by Arnold-Thomas Seed Service in the States of Nevada, Idaho, Oregon or Washington from breeders seed supplied by Countess von Arnim. Seed produced from any other stock, or from certified seed, will not be recognized by Arnold-Thomas Seed Service as Arnim.



5. 1966.







Caliverde 65



1. Caliverde and California Common 49 were crossed and the F1 crossed back to California Common 49. The backcross F1 was then crossed with C-84 (a parent clone of Lahontan) and the F1 of this cross backcrossed to the (California Common 492 X Caliverde) stock. After screening for spotted aphid, stem nematode and foliar disease resistance, 8 clones were selected.



2. Primary for hay production. To be recommended for coastal valleys, Sacramento Valley and areas in Northern San Joaquin Valley where stem nematodes are a problem.



3. Varying shades of purple flowers, very light pubescence. Fairly uniform. Similar to Caliverde in dormancy and recovery. Erect growth. Highly resistant to spotted alfalfa aphid. Similar to Caliverde in resistance to foliar diseases. Less resistant to stem nematode than Lahontan, but adequate to maintain stands.



4. Seed increase is on a 3-generation basis - breeder, foundation and certified. Breeders seed to be produced from 8 parental clones planted in a polycross nursery. Equal weights of seed from each clone to be composited. Foundation seed production in Sacramento and San Joaquin Valleys of California. Certified seed to be produced only from foundation seed. There will be no registered seed class.



5. Fall, 1966.



Mark II



1. Selection and progeny testing of clones from Narragansett. Twenty-five clones were selected as parents of Mark II from 100 clones originally selected from seed fields of Narragansett in Riverton, Wyoming, in 1957 and Firebaugh, California, in 1958.



2. Adapted in the Northeast where Narrangansett is used for all purposes - hay, silage, pasture and greenchop. Tested extensively in New York for forage production and in a limited way in other tests in the Northeast for forage production, tested in Oregon for seed production, and seed fertility studied in the greenhouse. To be marketed and recommended in the Northeast in the same way as Narragansett.



3. Flowers variegated, similar to Narragansett. Similar to Narragansett in uniformity, fall and winter dormancy, and growth habit. The number of yellow flowered or distinctly yellowish flowered plants may be fewer in Mark II than in Narragansett. However, one of the parental clones is pure lemon yellow and several are distinctly variegated in color.



4. The generation sequence is Breeder(Syn 1)-Foundation(Syn 2)-Certified (Syn 3) with the certified class ineligible for use as stock seed. The Breeder seed is composited from the seed produced by the random interpollinations by honey bees of 25 clones which are maintained vegetatively at Ithaca. Foundation seed production is limited to the Northern Region of Adaptation.



5. Fall of 1966.





Mesa-Sirsa



1. Thirteen parent clones were selected from an introduction from India, P.I. 235,736, for high resistance to the spotted alfalfa aphid and high general combining ability for forage production as determined by progeny tests.



2. Mesa-Sirsa is adapted to the lower desert valley areas of Southwestern United States where Moapa and Sonora are grown. Tested at locations in Arizona, California and Nevada.



3. Purple flowered with no variegation. Uniformly upright, nondormant -similar to Sonora. Much more resistant to both biotypes (Ent A and B) of the spotted alfalfa aphid than Moapa or Sonora as determined by seedling survival tests. More resistant to downy mildew than Moapa and Sonora.



4. Breeder seed was produced from a 0.4 acre planted near Yuma, Arizona, from plants obtained from inter-crossing 13 parental clones selected for a high resistance to spotted alfalfa aphid. Additional seed from these clones is available for establishing additional breeder seed fields as needed. Foundation seed will be produced from breeder seed. Production of foundation seed will be limited to the desert valley areas of the Southwestern alfalfa region. Certified seed will be produced from foundation seed. Seed generations beyond certified may not be called Mesa-Sirsa alfalfa.



5. Fall of 1966.



Scout





1. Scout is an 8 clone synthetic variety. The parent clones trace to Vernal, Narragansett, Ranger, Buffalo, and Cossack-Ladak, and were selected for one or more of the following: vigor, common leafspot resistance, potato leafhopper resistance, and wilt resistance. Progeny evaluations were made in polycross and diallel tests.



2. Scout will probably be used in the same area and for the same purposes as Ranger and Vernal are currently being grown. Yield plots have been grown in Indiana, Ohio, Massachusetts, and Minnesota plus observational plots in Kentucky, Tennessee, Virginia and Wisconsin.



3. Predominately purple with some green, cream, yellow and white present. Non-uniform, similar to Vernal in uniformity. Similar to Vernal in dormancy. Growth habit - variable, with some erect and some prostrate plants. Slightly faster recovery after cutting than Vernal. Blooms slightly earlier than Vernal or Ranger. Scout's leaf color is darker green than Ranger.



4. Parental clones will be maintained by F.F.R. at Lafayette, Indiana. Breeder seed will be the interpollinated, bulk harvested seed from an isolated planting of the 8 parental clones. Commencing in 1966, Foundation seed will be the 1st generation seed grown from Breeders seed in the Northern Area of Adaptation. Certified seed will be produced from either Breeders or Foundation seed. The present 560 acres established in California in 1965 and the 12 acres established in Washington in 1965 were from Foundation seed (Syn 2) produced in California from Syn 1 seed (seed from interpollinating the 8 clones). In no instance will seed grown from other than Foundation or Breeders seed be considered Scout by F.F.R.



5. Spring, 1966.



















Stride



1. Stride is a synthetic made by recombining clones initially chosen from a spaced-planted population of about 2000 plants on the basis of good seed yields, very good leafiness and color, and typical Flemish-type growth characteristics. Final selection of 16 parent clones of Stride was based on evaluation of 110 clones in replicated clonal tests at Atlanta, Illinois and Woodland, California.



2. Stride is adapted primarily for use as a hay crop in short rotation in the Central Corn Belt states, such as Iowa, Illinois, Indiana and Ohio, and the Northeastern States including Southeastern Canadian Provinces. Tests are established in Iowa, Illinois, Ohio, Kentucky, Tennessee, New York and Ontario.



3. Flower color - shades of blue to purple. Slightly more uniform than Du Puits. Late fall growth (early November in California) 14-l6 inches following early October irrigation in comparison with 9-10 for Ranger. Tall, upright, bloom date 4-5 days earlier than Ranger. Susceptible to spotted aphid, bacterial wilt, phytopthera root rot, and leaf rust. Moderately resistant to other foliage diseases, including mildew. Pods normally coiled, predominantly dark grey to black.



4. Breeder seed of Stride is produced from rooted cuttings of the 16 parental clones in isolation exceeding 1320 feet. Breeder seed fields are inspected by California Crop Improvement Association. Foundation seed is produced from breeder seed in California and inspected by California Crop Improvement Association. Only the first year seed crop is used for foundation seed production to avoid population shifts and certified seed is produced from either foundation seed or from second and subsequent year stands established with breeders seed. Commercial seed produced under limited generation different than that described above will not be recognized as Stride.



5. Spring, 1966.





Washoe



1. Parentage is largely from Nemastan. A large number of pea aphid resistant selections were evaluated by polycross performance for forage yield, insect resistance, wilt resistance and nematode resistance. From this group, 8 clones were selected.



2. Syn T is intended for forage production in those areas of Arizona, California, Idaho, Oregon, Nevada, Utah and Washington where Lahontan is presently adapted. It should extend into lower elevations north of the Lahontan area of adaptation where winters are not too severe and where leaf and stem diseases are not a problem.



3. Predominately purple flower. Similar to Lahontan in uniformity. Similar to Lahontan in fall dormancy but is slightly slower in recovery after cutting and slightly slower in spring growth. Upright growth habit. Has resistance to pea aphid.



4. Breeder seed is a composite of equal amounts of seed from each of the 8 parent clones which are intercrossed under isolation. Seed classes will include breeder, foundation and certified with breeder seed used to establish fields for foundation seed production and foundation seed used to establish fields for certified seed production. Foundation seed may be produced in California, Nevada, and Utah south to the 37E parallel, in Arizona, California and Nevada above 2500' elevation south of 37E parallel, and in areas of Idaho, Oregon and Washington below 4000' elevation. Breeder seed will be maintained by the Nevada Agricultural Experiment Station.



5. Fall, 1966.



522





1. 522 is a 20-clone synthetic composed of clones selected out of 5000 spaced plants of the variety Vernal, selection of clones being based on clonal and progeny performance.



2. To be used for hay, haylage, green chop, dehy and grazing in the areas where Vernal and Ranger are being used successfully. Tested in Iowa, Indiana, Wisconsin, Minnesota, Illinois, Pennsylvania and South Dakota.



3. Flower color ranges from deep purple to pale yellow. The occurrence of yellow and light flowered plants is more frequent than found in Vernal. Mostly glabrous. Semi-erect to erect, slightly taller than Vernal. Fall height measurements indicate that winter hardiness of 522 is similar to Vernal. Due to short and tall plants, a field appears somewhat irregular as it recovers from clipping.



4. The parental clones will be maintained by Arnold-Thomas Seed Service in California or other designated State. The procedure for maintenance of stock seed classes will be as follows: Breeder seed is produced from vegetative cuttings of the 20 parent clones randomized in a crossing cage or an isolated field and bulk harvested. Foundation seed is the first generation grown from breeders seed in the northern region of adaptation. Certified seed may be grown from either breeder or foundation seed, but only from these classes of stock seed. Seed produced from any other stock, or from certified seed, will not be recognized by Arnold-Thomas Seed Service as 522.
