Members of the Review Board met December 13, 1966. They were of the opinion that the varieties listed below were distinctive and merit certification. A supplemental report may be issued at a later date on applications for which insufficient information was provided for evaluation. Also included in this report are two varieties, Delta and A-59, which were reviewed initially at the 1965 meeting and subsequently given a favorable report.

Information pertinent to certifying agencies which was requested on

the application for each variety and the information submitted by the

applicants are given below. The respective applicants should be

contacted if additional information is desired.

Some of the Information Requested from Applicant:

1. A statement of the origin and the breeding procedures used in

developing the variety.

2. Area of probable adaptation and primary purpose (hay, grazing,

etc.) for which the variety will be used. Report States and areas

within States where the variety has been tested, and proposed areas of

recommendation and merchandising.

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. Clones were selected for vigorous fall growth and potato leafhopper

resistance from non-hardy, spotted aphid resistant lines. Clones with

fungus diseases were avoided. Replicated clonal nurseries containing

the same clones were established at Lafayette, Indiana, and Westley,

California. Selection of the 35 parent clones was based on the

performance of the clones at both locations plus single cross and

polycross progeny tests at Lafayette.

2. Bonanza will be grown for hay production in California and as a

one-year alfalfa in the Corn Belt. In actual hay fields, evaluation

has been limited to 1965 and 1966 crop years in California but seed

production fields have been harvested for three years without stand

problems. In the Corn Belt, seedling year yield tests have been

conducted in Indiana and Ohio plus observational plantings in

Wisconsin and Minnesota.

3. Flower color, growth habit, and leaf color are relatively uniform. Non-dormant and upright. Flowers are purple. Resistant to downy mildew.

4. Parental clones will be maintained by F.F.R., Lafayette, Indiana.

Breeder seed will be the interpollinated, bulk harvested seed from an

isolated planting made from vegetative cuttings of the 35 parental

clones. Foundation seed will be the first generation seed grown from

breeder seed in California. Certified seed will be produced from

either breeder or foundation seed. In no instance will seed grown from

other than foundation or breeder seed be considered Bonanza by F.F.R.

5. 1967.


1. N.S. 27 is an 8-clone synthetic. Six clones were selected from

North Central polycross progenies of clones that trace to Turkistan,

Cossack, Ladak, Kansas Common, and Baltic origin, and two were

selected from Ranger. All clones have antibiosis resistance to spotted

alfalfa and pea aphids. Resistance of all clones to spotted alfalfa

and pea aphids and bacterial wilt was verified in progeny tests.

Forage yields of open-pollinated progeny were not significantly

different from check varieties in the absence of economic levels of

insects or diseases.

2. The area of adaptation appears to be similar to Ranger. The variety

has been tested in the North Central region, including 4 locations in

Nebraska. The main usage will be for short- and long-term hay

production and in rotational pastures.

3. Purple, blue, and variegated flowers. Mostly glabrous, similar to

Buffalo, Ranger, and Vernal. Winter-hardy, intermediate between Ranger

and Vernal. Growth habit is intermediate between Ranger and Vernal.

Resistant to spotted aphid, pea aphid, and bacterial wilt.

4. Parental clones are maintained by vegetative propagation at

Lincoln, Nebraska. Seed classes will be breeder, foundation, and

certified. Breeder seed (Syn-l) is the bulk harvest from replicated

rooted cuttings of parental clones grown in isolated fields or in

cages pollinated by honeybees or other pollinators. Foundation seed

(Syn-2) is the first generation grown from breeder seed in the

Northern Region of Adaptation. Certified seed (Syn-2 or 3) may be

grown only from breeder or foundation seed. Number of years a field

may remain in production of a seed class is to be determined by the

certifying agency within that State.

5. Possibly some in 1967.


1. Maternal-line selection was used in developing Delta. Selection was

practiced for tolerance to root and crown rots, leafspot diseases and

leafhopper yellowing. Parentage traces to plants selected in 1948 and

1949 from an old field of Dakota 12 alfalfa near Leland, Mississippi,

and from other old alfalfa fields in the Yazoo-Mississippi Delta.

2. The Lower Mississippi Valley area of Missouri, Arkansas, Louisiana,

and Mississippi; also, the Red River Valley of Louisiana. For hay

and/or grazing purposes.

3. Purple to light blue flower. Relatively uniform in height,

erectness, flower color and stem size.

4. The Mississippi Agricultural Experiment Station will assume responsibility for the maintenance of breeder seed. There will be three generations of seed increase beyond breeder seed -- foundation, registered, and certified. Foundation seed supplies will be distributed through Foundation Seed Stocks, Mississippi State University, State College, Mississippi. Certification of seed fields shall be limited to stands not exceeding 6 years of age.

5. 1967.


1. Iroquois was produced by three generations of backcrossing and

selection for wilt resistance and desirable agronomic characters.

Vernal was the non-recurrent wilt-resistant parent and Narragansett

was the recurrent parent.

2. Iroquois is adapted for all environments and uses in the Northeast

suitable for Narragansett. It has been tested extensively in New York

and in six other Northeastern States. It will be marketed and

recommended in place of Narragansett, Vernal and Cayuga.

3. Similar to Narragansett in growth habit and flower color.

4. Iroquois is to be produced on the limited generation sequence of

breeder-foundation-certified with the certified class ineligible for

use as stock seed. The breeder seed production field is planted with a

composite of seed from crossing approximately 500 parent clones.

Breeder and foundation seed is produced in the Pacific Northwest;

parent clones are maintained vegetatively at Ithaca, New York. A

reserve of breeder seed will be kept in storage.

5. 1968 in very limited amounts since production will come from

seedling stands to be planted in the spring of 1967.


1. A-59 originated from selected clones in established seed fields of

certified Vernal, certified Ranger, and Common alfalfa in Eastern

Montana in 1957.

2. A-59 is adapted to the hay-producing areas of the Central United

States. It has been included in the evaluation trials conducted by

the Illinois Experiment Stations at DeKalb and Urbana, and by the

Missouri Experiment Station in Mt. Vernon.

3. Flower color is variegated but less so than Vernal.

4. Seed production of A-59 shall be on a four-generation basis:

breeder, foundation, registered and certified. Breeder seed will be

maintained by Farm Seed Research Corporation and will consist of seed

harvested in 1962 and 1963 from the original 540 parental plants.

Breeder seed will be released only to Ed F. Mangelsdorf & Bro., Inc.,

St. Louis, Missouri, for production of foundation seed. Foundation

seed will be used for production of registered or certified seed.

Certified seed fields will be established with foundation seed, except

in an emergency when registered seed will be used. Foundation and

registered seed will be produced in Kansas.
