The current study evaluates quality of the particular malting barley varieties and quality of barley in the individual districts and regions of the Czech Republic. Year 2009 with a delayed onset of spring and first of all lack of precipitation in April was very similar to 2007. That year recorded lower hectare yields; barley had higher protein content and lower starch content. However, in 2009 it was confirmed that the delayed vegetation generally managed to utilize June's and also July's rainfalls to achieve favorable barley yield and quality and the fears (that 2007 can equal 2009) did not fulfill.The current study evaluates quality of the particular...

Evaluation of α- and β-bitter acids content of hops in hops crop 2009 in Czech Republic has been carried out. Sampling map concerned all three growing areas - Žatec (73.5 % of hop gardens area in CR), Úštěk (12.6 %) and Tršice (13.9 %) area. Saaz hop variety was growing on 4,627 ha, other important varieties were Sládek (277 ha) and Premiant (293 ha). Hops were analyzed according to EBC method 7.7 (HPLC), all results are expressed as % w/DM. Average value of bitter acids content of Saaz hops variety in Czech Republic was α = 3.9 % (Žatec growing area 4.1 %, Úštěk growing area 3.7 %, Tršice growing area 3.6 % ), β = 4.9 %. The value...

forage production area, crop 2009. Kvasny Prum. 56, 2010, No. 4, p. 195-200. In 2009 collection of the genetic resources of barley was grown under the same conditions as the current standard varieties in one testing site in the forage production area. Most of the old varieties achieved full ripeness even by 9 days earlier than the standard varieties. The standard varieties and also a number of older ones had 800 and more productive stems per m2 and about by 1.5 t/ha higher yield of grain. The standard varieties and breeding lines were on average by 30 cm lower than the other varieties studied. Weight of one thousand grain varied in the range from 28.3...
