1.
DryLand is a 150 clone synthetic variety. Parent plants were selected
out of a 27-year-old stand of Ladak in eastern Washington. These plants
were selected for visual herbage yield, seed yield, drought tolerance
and root and crown health. Fifty plants were selected out of AC Minto
for Phytophthora root rot resistance. Selected plants were hand
pollinated in greenhouse near Sloughhouse, CA. Seed from hand crosses
were bulked to produce Syn. l as breeder seed in l998. 2. DryLand
is adapted in the North Central region of the United States. It is
intended for use in the North Central and Winterhardy Intermountain
regions of the United States. The state in which it has been tested is
Wisconsin. 3. Dry Land is a dormant, fall dormancy 3 variety, similar to the fall dormancy 3 checks. Flower color in the Syn. 2 generation is 90% purple, 7% variegated, 1% cream, 1% white, and 1% yellow. 4.
DryLand has high resistance to bacterial wilt, Fusarium wilt; resistance
to Phytophthora root rot; moderate resistance to stem nematode,
anthracnose (Race 1), northern root knot nematode; low resistance to
Verticillium wilt and susceptible to Aphanomyces root rot (Race 1). Its
reaction to spotted alfalfa aphid, blue alfalfa aphid and pea aphid has
not been tested. 5.
Breeder seed (Syn. 1) was produced from hand-pollinated crosses made in
greenhouse near Sloughhouse, CA in 1998. Foundation seed (Syn. 2) was
produced from Breeder seed and Certified seed (Syn. 3) from Foundation
seed. One generation each of Breeder, Foundation and Certified seed
classes are recognized. A maximum of three years each is permitted on
stands producing Breeder and Foundation seed with five years for
Certified seed. Dairyland Research International will maintain
sufficient Breeder seed for the projected life of the variety. 6.
Certified
seed will be available spring of 1999. 7.
Application
for Plant Variety Protection is anticipated. 8.
