The 2000 Alabama Performance Comparison of Small Grain Varieties
K. M. Glass and P. L. Mask1

INTRODUCTION
The large number of commercially available varieties of wheat, oat, rye, barley, and triticale makes it difficult for growers to select varieties most suited for their particular area of Alabama. Making this decision requires up-to-date, unbiased, reliable information on varietal yields and characteristics. This report is published annually to provide Alabama growers with this information. This report may also be obtained under Publications at the following website: http://www.ag.auburn.edu/resinfo/ Entries in each experiment are determined by the companies or institutes which control each variety or line, not by experiment station personnel. Data from tests conducted at eight locations were used to compile this report. These locations represent the varied growing conditions farmers have around Alabama.

PROCEDURE
The experimental design for the tests was a split plot design with species as the main plot and varieties as subplots. Plots were 5 feet by 20 feet with rows spaced 7 inches apart. A cone drill was used to plant all tests. Each variety was replicated three times in each test. The trials were divided into two management systems: grain only and forage only. Grain only: These tests are normally planted during late October to early November, which is approximately one month later than the forage tests. Planting dates for all tests in 1999 are shown in Table 1. All tests were fertilized with phosphorus (P) and potassium (K) according to soil test plus 20 pounds nitrogen (N) per acre at planting. A top dressing of 60 pounds N per acre was made in late February or early March, just before jointing. The plots were not sprayed to control disease so that the varieties could be rated for their inherent disease resistance. The grain was allowed to mature, harvested with a plot combine, then cleaned and weighed. Moisture and bushel test weight were measured. Forage only: These tests are normally planted in late September to early October. Tests were fertilized at planting with 100 pounds N per acre and clipped with a flail-type mower each time they reached 6 inches in height. A sample was weighed green from each plot, then dried and reweighed. The percent dry matter figure from these weights was used to calculate dry forage matter per acre. The test was top dressed in February with 60 pounds N per acre and clipping was continued until no regrowth occurred.

DATA EXPLANATION
Grain yields were calculated by weighing air-dried grain and using 60 pounds per bushel for wheat, 32 pounds per bushel for oat, 48 pounds per bushel for barley, and 50 pounds per bushel for triticale. Lodging was measured as the percent of plants in the stand broken or leaning that would likely be missed by a combine. Height was measured from the ground to top of the grain head. The 1/10 headed date is the date when approximately 10 percent of a plot showed fully emerged heads. Disease ratings for all 1999-00 variety tests are summarized by region in tables 13 through 20. Katherine B. Burch, Research Associate, Department of Plant Pathology, made disease ratings at all locations. Disease onset on

wheat was earlier in the southern and central locations than in previous years. At the time of mid-season ratings, incidence of leaf rust and powdery mildew was slightly higher than in 1999, while incidence of Septoria was little changed. In northern regions, stripe rust, not normally seen in Alabama and thought to have blown over from Arkansas, was observed in many entries. The viral disease barley yellow dwarf was higher throughout the state than in previous years on wheat, oats, barley, and triticale. Levels of Helminthosporium leaf spot on oats were slightly higher; however, indicence and severity of crown rust were mostly unchanged from previous years. Low levels of leaf rust and Septoria blotch were observed on triticale at most northern and southern locations. Spot blotch, net blotch, and Septoria blotch developed on barley at low levels.

DISCUSSION
Growing conditions and variety performance often vary among locations and years. The 1997-98 growing season was a mild, wet fall and winter with a dry spring. Neither the forage- nor the grain-only trials were planted at the Black Belt Research and Extension Center, Marion Junction, due to dry then wet conditions during planting season. In the 1998-99 growing season, planting was delayed at several locations due to dry soil conditions. The 1999-00 growing season had mild temperatures with a fairly dry spring. At Gulf Coast Research and Extension Center, Fairhope, planting was delayed due to dry soil conditions. Regional averages and multiple-year averages are given here to use as better indicators for performance comparison.

Barley Yellow Dwarf Although Barley Yellow Dwarf is a significant problem in Alabama, no current oat or wheat varieties have adequate resistance to this disease. All oat and wheat varieties are susceptible. Hessian Fly In the 1996-97 and 1997-98 growing seasons biotype ‘L’ of hessian fly was found in Alabama. This biotype represented only a small portion of the population. The level of resistance to hessian fly as shown in the table is only valid for the biotypes other than ‘L’ since none of the current commercial varieties are resistant to this new biotype.
