After a long interruption of the barley breeding program at Dobrudzha Agricultural
Institute, a two-rowed winter barley variety GTE Ahat was released. The aim of
the investigation was to analyze its biological and economic properties. Results
are presented from the two-year testing at the national Executive Agency of
Variety Testing, Field Inspection and Seed Control (EAVTFISC). The new cultivar
exceeded by yield the mean standard at all testing locations in Bulgaria. Averaged
for the period of investigation, the relative yield was with 8.7 % higher. The date to
heading was with 1-2 days earlier than that of the standard. Under filed conditions,
the variety demonstrated high resistance to powdery mildew and brown rust. The
technological evaluation of the new variety showed higher 1000 kernel weight
and high grain uniformity. By brewing properties, the variety equaled the mean standard. The advantages of GTE Ahat are high resistance to lodging and to net
blotch attack.
