ABSTRACT
Results of three-year trials (2003 to 2005) conducted with four winter triticale varieties to investigate the effect of sites and years on quality characteristics and ethanol yield showed a statistically highly significant effect of sites (P < 0.01) on the quality parameters of test weight, falling number, protein content, starch content, grain yield and ethanol yield. Climate conditions showed a statistically highly significant effect (P < 0.01) on test weight, thousand grain weight, falling number, Zeleny sedimentation test, starch content, grain yield and ethanol yield. Percentage of complete grains and protein content were non-significant. The effect of the variety was highly significant (P < 0.01) on the quality parameters of test weight and percentage of complete grains and there was a significant effect (P < 0.05) on falling number, Zeleny sedimentation test and starch content. Regarding the bioethanol yield, the most suitable variety according to the measured values was the variety Modus (average 41.19 la /100 kg dry matter). The variety Disco provided the largest yield on the site Hradec nad Svitavou in 2005 (46.7 la /100 kg dry matter), which agrees with starch content. Year 2003, when the starch content in grain was at the lowest level (63.41%), resulted in the lowest bioethanol yield.
