Beer is one of the first beverages people made, and nowadays it is the most
popular drink in many places all over the world. From ancient traditions to modern
technologies, the main raw material for its production has been the barley malt. In
breeding, however, it is extremely difficult to combine a complex of traits meeting
the demands of the consumers, the grain producers and the brewers. In most cases
the successful enhancement of the production potential causes deterioration of
stress tolerance and quality. The use of donors with good combining ability and
different genetic basis is the most realistic possibility for development of malting
barley varieties which combine a greater number of desired traits at an acceptable
level. In 2012, with order No RD 12-19 of the Ministry of Agriculture of Bulgaria, a
two-rowed winter barley variety GTE Yaspis, developed at Dobrudzha Agricultural
Institute – General Toshevo, was released. The variety is protected with certificate
No 11039 / 31.03.2014 of the Patent Agency. The aim of this investigation was to make economic characterization of two-rowed winter barley variety GTE Yaspis.
The biological and economic properties were evaluated within the system of the
national Executive Agency of Variety Testing, Field Inspection and Seed Control
(EAVTFISC) during 2009 – 2010 and 2010 – 2011. Averaged for the period of
testing, the relative yield was with 8.3 % above the national standards. The date to
heading was simultaneous with that of cultivar Emon and 2-3 days earlier than that
of cultivars Obzor and Kaskadyor 3, but the duration of the vegetative growth was
equal to their. The technological assessment of the new variety showed higher 1000
kernel weight and high uniformity of grain. By malting properties, the variety was
equal to the mean standard. The advantages of GTE Yaspis are high resistance to
net blotch and to unfavorable winter conditions.
