'Morey' is a soft red winter wheat (Tri.ticum aestivum:: L.)
cooperatively developed and released by the Georgia and Florida
Agricultural Experiment Stations in 1994. It was named to honor
Dr. D. D. Morey, the former small grain breeder at'the Coastal
Plain Station, Tifton, Georgia. Morey was derived from a single
cross made in 1985 at the University of Florida: FL8172-
G116/Florida 303. FL8172-G116 is a sister line to Florida 304 and
has the following pedigree: FL74265-10-A2-B2/Coker 80-29. The
cultivar was developed using a modified pedigree method of
breeding. Individual spike selections were made in the F3, F4, and
F5 generations at Tifton, GA. Morey was selected as an F5 headrow
in 1990. Morey was tested experimentally as GA85238-C5-AB5-4. It
was:first included in yield evaluations in 1991. It was included
in state trials in Georgia and Florida in 1992 and 1993 and in the
Uniform Southern Soft Red Winter Wheat Nursery at about 30
locations in 1992 and 1993.

Morey has a low vernalization requirement and is very early
maturing in the Southeast. It is a medium height at maturity,
white-chaffed, awned, and characterized by good straw strength with
High yield potential. .It::is about 5 days earlier in maturity and
;- 3 inches shorter than Florida :304 and has excellent lodging
ri;: resistance : Milling and baking quality characteristics of Morey
are rated acceptable for soft red winter wheat use by the USDA-Soft
Wheat Quality Laboratory, Wooster, Ohio.
Morey is resistant to the biotypes E, G, M, and of Hessian
fly (Mavetioia destructor (Say)) present in Georgia and Florida.
It is resistant to current races of leaf rust caused by Puccinia
recondita (Rob. ex Desm.), and powdery mildew caused by Erysiphe
g-raminis f. sp. tritici Em. Marchal.
Performance and agronomic characteristics of Morey compared to
other varieties currently available when grown in Georgia is
presented in Tables 1 and 2. Performance when grown in Florida is
presented in Tables 3-9.
Breeder seed will be maintained by the Georgia Agricultural
Experiment Station, University of Georgia, Georgia Station,
Griffin, GA 30223-1797. Application for plant variety protection
will be made to the Plant Variety Protection Office and it will
specify that Morey is to be sold by variety name only as a class of
certified seed.
