ABSTRACT
The research of the production values of 10 sugar beet hybrids was conducted at the location Dalj from 2009-2012. Hybrids included in the experiment are owned by four selection houses and represented in wide production. Weather conditions in the years of investigation differed greatly. One was an average, one with increased, and two with small amounts of rainfall in relation to long-term average. Monthly air temperatures during the vegetation were increased in all four years. Root yield and quality of sugar beet varied considerably depending on the year and the hybrid. The best hybrid on the average of the investigation, by the highest root, was Severina (86.66 t ha-1). Three more hybrids: Coyote, Boomerang and Predator are in the same range. There are no significant differences in this indicator. Hybrid Colonia KWS (15.40%) had the highest content of sugar in the root and Asketa, Gazeta, Severina and Protecta with no significant differences. Hybrid Colonia KWS was known for the low content of AmN and Na. Sugar yield, significantly higher than other hybrids in the study, has been realized with hybrids Severina (11.05 t ha-1) and Colonia KWS (10.78 t ha-1).
