CULTIVAR: GA-Luttrell, a winter barley was developed at the University of Georgia Agricultural Experiment Station in cooperation with the USDA-ARS and released in 1994. GA-Luttrell was derived from a single cross made in 1981: 'Volbar' / 'Sussex'. It was named to honor Dr. E.S. Luttrell, the former plant pathologist at the Georgia Station, Griffin.
The cultivar was developed using a modified pedigree method of breeding. Individual spike selections were made in the F2, F3, F4, and F5 generations at Griffin, GA. GA-Luttrell is the progeny of two rows with similar phenotype bulked together after selection from 100 head rows in the F7 generation. GA-Luttrell was evaluated for agronomic performance as GA 81814 in nursery plots in 1989 and 1990, in state trials at five locations in each of 3 years, (1991 through 1994), and in the USDA Uniform Winter Barley Yield Nursery in 1992 through 1994.
GA-Luttrell is a bearded, six-row, early-maturing, medium tall feed barley characterized by excellent straw strength. State trials from 1991 through 1994, GA-Luttrell and 'Venus' yielded an average of 5174 and 4699 kg ha-1, respectively. It is 1 d earlier in maturity than Venus. GA-Luttrell is similar in plant height to Venus, and is superior in standability. In 8 trials, lodging of GA-Luttrell was 18%, compared to 58% for Venus. GA-Luttrell was tested in the USDA Uniform Winter Barley Yield Nursery over a 2-yr period (1992 and 1993). GA-Luttrell, 'Milton', and 'Wysor' yielded an average of 5385, 4752, and 4276 kg ha-1, respectively. GA-Luttrell has resistant to scald and BYDV.
