DEFENDER
1. Defender was developed by recombining two populations selected for
having resistance to Phytophthora root rot, with a population having
resistance to anthracnose. (All three populations were selected from
Thor.) The two Phytophthora resistant populations, THPT--5 and
MW--74--4PT, were developed through several cycles of phenotypic
recurrent selection in which 26 to more than 100 plants were saved in
each cycle. The population having resistance to anthracnose, 74TH-An,
was developed through two cycles of selection in which 43 and 50
plants were saved at cycles one and two respectively. Approximately
20% outcrossing to other anthracnose resistant plants occurred
following cycle one. A composite of 40% THPT--5, 10% MW--74--4PT and 50%
74TH--An was pollinated under cage isolation to produce MW--76--12 (Syn
2). MW--76--12 was increased to produce K7--28 (Syn 2).
2. Defender has been tested in Iowa, Nebraska, Minnesota, Tennessee,
Missouri, Montana and Washington. It is well adapted to the Northern
and Central regions of the U.S. where it will be used primarily for
hay, haylage and greenchop.
3. Fall dormancy is similar to Saranac--AR. Flower color is
approximately 43% light purple, 39% medium dark purple, and 18% dark
purple.
4. Defender has resistance to bacterial wilt, moderate resistance to
anthracnose, Phytophthora root rot, pea aphid and stem nematode; it
has low resistance to spotted alfalfa aphid and Fusarium wilt and
tolerance to potato leafhopper yellowing.
5. Seed classes will be breeder, foundation and certified. Adequate
breeder seed (Syn 2) has been produced to last the expected life of
the variety. Limitation on age of stand for each class will be two,
three and five years for breeder, foundation and certified
respectively.
6. Certified seed will be available in 1981.
7. Application for plant variety protection is not planned.
POLAR II
1. Polar II was developed from an intercross of plants selected from
Polar I and Iroquois. Polar I underwent two cycles of selection for
resistance to Phytophthora root rot. Ninety two plants were selected
in cycle 1 and 139 plants in cycle 2. Iroquois underwent five cycles
of selection for resistance to Phytophthora root rot, with 33 plants
initially selected and over 100 plants in subsequent cycles. Equal
quantities of seed from these reselected populations were bulked and
interpollinated under isolation to produce MW--76--3 in 1976. During
1977, MW--76--3 was randomly pollinated in isolation to produce K7--25
(breeder seed) of Polar II.
2. Polar II is best adapted to the Northern region of the U.S. It has
been tested in Minnesota, Wisconsin and Iowa.
3. Flower color is approximately 13% dark purple, 64% medium dark
purple, 13% light purple and 10% variegated. Fall dormancy is similar
to Saranac.

VANCOR
1. Vancor was developed by combining two pest resistant populations which were developed independently of each other. KOPT4 was the result of four cycles of selection from Gladiator for Phytophthora root rot resistance in the disease nursery at Stanton, MN. Thirty--four plants were selected in cycle 1 and more than 100 plants in each of cycles 2 through 4. MW75--15 was the result of one cycle of selection for anthracnose in the greenhouse at Washington, IA. Twenty--nine plant selections from Arc contributed 50% of the germplasm to MW75--15 and 16 selections from Gladiator contributed the remaining 50%. Equal amounts of seed from the two populations, KO2PT4 and MW75--15 were bulked and pollinated under cages at Woodland, Ca., to produce MW76--9 (Syn 1) in 1976.
