3. Information of value to field inspectors (such as uniformity, leaf, flower characteristics, etc.), physiological characteristics, obvious disease and insect reactions, and other identifying characteristics.
4. Procedure for maintaining stock seed, seed classes to be used, a statement as to the limitations of generations that may be certified, and any other requirements or limitations necessary to maintain varietal characteristics.
5. If this variety is accepted by official certifying agencies, when will certified seed first be offered for sale?
Information Submitted by Applicant on the Above Points:
1. Individual plant selections derived from Arnirn, Culver, Narragansett, Vernal and a recurrent selection population were subjected to clonal evaluations in the Midwest and California, bacterial wilt screening, progeny testing far forage yield, leaf diseases, winterhardiness and adaptation and finally, an evaluation of restricted polycrosses and the variety.
2. Evaluated in Iowa, Indiana, Illinois, Minnesota, Wisconsin, Pennsylvania and California. It is adapted and will be marketed in areas of the Northern and Central Regions of adaptation where Vernal or Ranger are presently grown for hay, haylage, de-hy, green chap or grazing.
3. Flower color dark purple through variegated to a few plants with yellow flowers. Fall and winter dormancy is between Vernal and Ranger. Dark green color of foliage. Has more resistance to Leptosphaerulina leaf disease than any other alfalfa with which it has been compared. Has resistance to downy mildew.
4. Breeder seed is a composite of seed produced on the 8 parent clones replicated and randomized either in a cage or an isolation. Foundation seed is the first generation grown from breeder seed under the supervision of the originator. The only authentic certified seed of ATRA 50, according to the originator, will be that produced from breeder or foundation seed.
1. Individual plant selections tracing to Vernal, Narragansett, Arnim, Culver and a recurrent selection population followed by replicated clonal evaluation, bacterial wilt evaluation, open-pollination progeny testing for forage yield, leaf diseases and adaptation, restricted polycross progeny testing for forage yield and finally, multiple-row plot evaluation of the variety.
2. Adapted to areas of the Northern and Central Regions of adaptation where Vernal and Ranger are presently grown for de-hy, hay, haylage, green chop or grazing. It will be merchandised in these States. ATRA 55 has been evaluated in Iowa, Indiana, Illinois, Minnesota, Wisconsin, Pennsylvania and California.
3. Flower color - dark purple through variegated to a few plants with yellow flowers. Fall and winter dormancy approximates that of Vernal. Dark green color of foliage with some resistance to downy mildew and Leptosphaerulina leaf spot.
4. Breeder seed represents the composite from the 8 parent clones replicated and randomized either in a cage or an isolation. Foundation seed is the first generation grown from breeder seed produced under the supervision of the originator. The only authentic certified seed of ATRA 55, according to the originators, will be that produced from breeder or foundation seed.
5. Late in 1968.
1. Two clones selected from African were randomly pollinated to make a two-clone Syn1 and five selected clones of Afghanistan were randomly pollinated to form a five-clone Syn1. These Syn1 lines were increased individually by bee pollination in cages. Seed from these caged plants was planted in alternate rows in an isolated field plot and bee pollinated. Seed from this plot makes up the breeder seed. Approximately equal populations of the Syn1 lines are maintained in the breeder nursery.
2. To be grown primarily in the San Joaquin and Sacramento Valleys of California for hay and green chop. Other possible areas of adaptation are Arizona, New Mexico, and Texas; excluding the low desert valleys. Testing has been in the Sacramento, San Joaquin, and Imperial Valleys of California.
3. Purple-flowered, very uniform. Nondormant, but has a slightly greater degree of dormancy than does Moapa. Exhibits rapid recovery. Upright growth habit. Resistant to spotted alfalfa aphid. Pods dark brown when dry, full curl.
4. A 3-acre plot for producing breeder seed has been established at San Joaquin, California, by drilling in alternate 40" rows the seed from the two Syn1 lines. Seed stocks of the original clones are maintained to keep populations of the lines approximately equal and to reestablish the plot if necessary. Certified seed may be produced from breeder or foundation seed only. Foundation and certified seed shall be produced in the San Joaquin Valley of California.
1. Elite bacterial wilt resistance plants selected from polycross progenies of clones that trace to Kansas Common and Turkistan x Kansas Common derivatives were crossed with spotted alfalfa aphid resistant clones from Culver. The progenies were screened in the greenhouse for resistance to the pea aphid, spotted alfalfa aphid and bacterial wilt. Plants selected from the survivors on basis of agronomic characteristics and disease resistance in the field were crossed with plants derived from Cody through the same selection program. The seven parental plants of the synthetic KS12 were the result of reselection from the progenies for the same traits.
2. Winter hardiness of KS12 appears to be about equal to that of Cody and Buffalo. The variety has been tested in the North Central Region. The main usage will be for hay production and in rotational pastures.
3. Flower color ranges from blue to purple. Uniformity and fall dormancy are similar to Buffalo and Cody. Growth habit is upright, similar in height to Buffalo and Cody. Foliage is darker green than Buffalo and Cody. Resistant to bacterial wilt, pea aphid, and spotted alfalfa aphid. Pod color brown to black, coiled pods.
4. Parental clones are maintained by vegetative propagation at Manhattan, Kansas. Seed classes will be breeder, foundation, registered, and certified. Breeder seed (syn-l) is a composite of equal amounts of seed from each of the seven parent clones which are intercrossed under isolation. Foundation seed (syn-2) is the first generation grown from breeder seed. Breeder and foundation seed will be produced under the direction of the Kansas Agricultural Experiment Station. Registered seed (syn-3) is the first generation grown from foundation seed in the Central Alfalfa Region. Certified seed may be grown only from foundation or registered seed.
1. Product of six cycles of phenotypic selection for weevil resistance initiated by intercrossing 66 plants selected for low larval damage in 1957 at Raleigh, N.C. More than one-half of the 66 selected plants were from polycrosses of N.C.-selected clones tracing to plantings of polycrosses and synthetics obtained from Kansas and Nebraska in 1946. Other plants were from Narragansett, Atlantic, Rhizoma, and DuPuits. Four of the six cycles of selection were conducted in the field -- two each in North Carolina and Maryland. The fifth and sixth cycles of weevil selection were conducted in laboratory at Beltsville, Md.
2. Team, its preceding cycles, and the original lines have been undergoing field selection or observation since 1946. That information and test data indicate that it is well adapted to a considerable part of the Maryland-Virginia-North Carolina area.
3. Slower color - predominantly purple and blue with a low frequency of variegated types. Quite variable in growth habit. Fall dormancy is similar to Cherokee and Saranac. Upright growth habit but characterized by well developed axillary branching. Pods coiled, typical of M. sativa. More resistant to anthracnose, Stemphylium leafspot, common leafspot and pea aphid than other varieties adapted to mid-Atlantic area. 4. There shall be one generation each of breeder, foundation, and certified seed classes. Breeder seed production is from an isolated planting of 10,000 plants of MSHp7. A reserve of breeder seed will be maintained by Crops Research Division, Beltsville, Md. The area of production for foundation seed is defined as that north of the 40 latitude at elevations below 2,500 feet in the States of California, Nevada, Oregon, Idaho, and Washington. A request will be made to place Team in the National Foundation Seed Project.
5. Spring 1970.
1. An 11-clone, limited generation, synthetic variety. Parent clones isolated from 55 selections made in 4-year--old, decimated, Vernal source nursery in 1963 and evaluated in extensive clonal, S1, polycross and single cross tests from 1963-67 in Midwest and Pacific Northwest for insect and disease resistance, seed and forage traits, and combining ability. 2. Evaluated in Kansas, Nebraska, South Dakota, Minnesota, Iowa, Illinois, Wisconsin, Indiana, Oregon, Idaho, Ontario and Quebec. Adapted to North Central Region, Pacific Northwest, Southern Canada, and Northeastern States where Vernal ss used and good hardiness and bacterial wilt resistance desired. Suited for all purpose forage use in short and long term stands.
3. Flower color - ranges from purple, blue, variegated to yellow and white. Variegated percentage is greatest with purples intermediate, and yellow and white a small percentage. Winter dormant, somewhat more vigorous, taller and erect in late summer and fall than Vernal. Moderately fine stems - similar to Vernal, blooms several days earlier. Moderately tolerant to leafhopper yellowing, high Level of bacterial wilt resistance, some tolerance to pea aphid. 4. Breeder seed produced in 1967 in isolated, replicated block of about 1,000 cuttings of each parental clone near Caldwell, Idaho, using heavy load of leafcutter bees. Foundation seed production fields planted only in Pacific Northwest with breeder seed and inspected by Idaho and Washington Crop Improvement Associations. Commercial or certified seed production fields planted with breeder or foundation seed only. Seed produced on fields not planted with breeder or certified foundation seed will not be recognized as Titan by the Rudy--Patrick Seed Division of W. R. Grace and Company.
1. Twenty-five clones that survived for 3 or more years in Maryland under existing, uncontrolled weevil populations were combined by natural cross pollination in l963 to produce 63 CaA.; 5 were from Ranger, 3 from Atlantic, 1 from Buffalo, and 16 from Vernal. Concurrently, most of these clones were progeny tested for forage yield and persistence in the Midwest. 2. Primarily a hay variety for the Midwest.
3. Flower color - 50% purple and bluish purple; 42% variegated and 8% white, yellow and cream. Uniformity of growth is similar to Vernal. Semi-decumbent.
4. 63 and 64 Cage A seed comprises the breeder seed of WL 215. Foundation seed is grown only from breeder seed in the northern area of adaptation. Certified seed will be grown only from foundation seed. No other seed generation or class of seed is to be used.
1. Eight clones selected for high seed yield and resistance to leafhopper yellowing from 62 WB (4), Vernal (3) and Atlantic (1) were combined in a 0.2--acre isolated block at Bakersfield, California in 1964. The 1964 and 1965 harvests from this block comprise the breeder seed of WL 305.
2. Central Cornbelt and adjacent areas where WL 303 has performed best, but where a higher level of bacterial wilt resistance is required. For hay or green chop.
3. Flower color - approximately 70% purple, 25% variegated and 5% white and yellow. More uniform in appearance than WL 303, less uniform than DuPuits or Cardinal, similar to Cody in uniformity. Fall and winter dormancy - After a September 9 harvest at Waterloo, Nebr., the October 7 height of WL 305 was 9.2"; WL 303, 9.8"; WL 202, 7.2" and Vernal, 6.0" with the LSD at .05 = 0.9". Upright growth habit. Darker green in color under leafhopper attack than Cody, Ranger and Buffalo.
4. Breeder seed is produced by growing the eight parent clones in isolated open pollination. Foundation or registered seed is produced from breeder seed between the 35 and 43 parallels. Certified seed will be produced only from breeder seed or the first increase of breeder seed, whether it be foundation or registered.
