PREFACEThis research report presents results of the 2017-2018 performance tests of smallgrains grown for grain and forage. Grain evaluation studies were conducted at fivelocations in Georgia, including Tifton, Plains, and Midville in the Coastal Plain region;Athens in the Piedmont region; and Calhoun in the Limestone Valley region. Small grainforage evaluation tests were conducted at four locations in Georgia/Florida, includingTifton and Plains in the Coastal Plain region, Athens in the Piedmont region, Calhoun inthe Limestone Valley region, and in Marianna, Florida. Prior to 2017, Piedmont regiontrials were located in Griffin. For identification of the test locations, consult the mapinside the back cover of this report.Grain yields are reported as bushels per acre at 13.5% moisture for wheat, 13%moisture for triticale and rye, 12.5% moisture for oats, and 12% moisture for barley.Additional agronomic data, such as plant height, lodging, and disease incidence, arelisted along with the corresponding yield data. Footnotes include information concerningfertilization and cultural practices used in the tests. Since the average yield from severalyears indicates a variety's potential better than a single year's data, multiple year yieldsummaries are included.In order to have a broad base of information, a number of varieties, includingexperimental lines, are included in the tests, but this does not imply that all arerecommended for Georgia. Varieties best suited to a specific area or for a particularpurpose and agreed upon by College of Agricultural and Environmental Sciencesscientists are presented on pages 4 and 5 and also in the 2018 Fall Planting Schedulefor Georgia (available at your county Extension office). For additional information,contact your local county Extension office, the nearest UGA campus, or the nearestUGA Research and Education Center.The least significant difference (LSD) at the 10% level has been included in thetables to aid in comparing varieties and tests. If the yields' difference of any twovarieties exceeds the LSD value, they can be considered different in yield ability.Bolding is used in the performance tables to indicate entries with yields statisticallyequal to the highest yielding entry in the test. The standard error (Std. Err.) of an entrymean is included at the bottom of each table to provide a general indicator of the levelof precision of each variety experiment. The lower the value for the standard error of theentry mean, the more precise the experiment.This report is one of four publications presenting the performance of agronomiccrops in Georgia.

SMALL GRAIN UPDATESDISEASESJames W. Buck, Alfredo Martinez-Espinoza, and John D. YoumansDepartment of Plant PathologyUniversity of Georgia – GriffinGeorgia wheat acreage for grain production was again low this year. Fall, 2017 wasexceptionally wet and many production fields were planted late. However, no problemswith seedling emergence were observed. Plantings in the state received adequaterainfall into December. In December the southern half of the state began receivingmuch less rainfall than the northern half of the state. This trend continued through thewinter and spring. Low temperatures late in the winter caused some cold damage towheat. Late rains in May greatly hampered harvest and affected grain quality as well.Powdery mildew (Blumeria graminis) was observed throughout the state and foundat high levels at Calhoun and Tifton CAES research and education centers. Mildew wasalso observed at Plains and Midville.Fusarium head blight (FHB/Scab) (Fusarium graminearum) incidences were lowacross the state. Only one sample with confirmed FHB originated in Grady county inextreme south GA where the infection was minimal. The dry winter and springprevented infections from starting. This does not mean that we no longer have a scabproblem in Georgia. Given the amount of corn that is being grown across the state, wewill have a reservoir of inoculum for the foreseeable future. Cool wet winters andsprings will again lead to outbreaks of FHB. Please refer to UGA Extension Publication(c 1066), “Identification and Control of Fusarium Head Blight (Scab) of Wheat inGeorgia” for additional information on dealing with FHB.Leaf rust (Puccinia triticina) was observed at all research locations in the state.Disease levels were low. Mild winter and spring temperatures as well as intermittenthumidity did not provide conducive conditions for leaf rust epidemics. Higher infectionrates were observed later in the season on susceptible varieties. Stripe rust (Pucciniastriiformis) was observed at Plains where plots were artificially inoculated and also inTifton and Midville at low levels. For additional information on leaf rust html?number C1060. Oat crown rust(Puccinia coronata) incidences were numerous and severity was high in commercialfields. Crown rust was observed at Plains and Tifton in the oat variety trial. Therecurrently is not much resistance to this disease in available production varieties.Stagonospora spot blotch and tan spot were observed throughout the state at lowlevels in wheat. Tan spot was also reported on rye in the state. Barley yellow dwarf virus(BYDV) was observed at low levels across the state.6Annual Publication 100-10 Georgia 2017-2018 Small Grain Performance Tests
