Variation in the Yield of Root, Sugar and the Quality of Sugar Beet Depending on Variety and Soil Infestation with Rhizomania

Abstract

Sugar beet field trials were planted in 2004 in order to determine sugar and root yield and the quality of sugar beet varieties depending on varietal tolerance to Rhizomania. The field trials were located at the agricultural station in Kikinda, covering a highly infested area and at the "Agroinstitut" in Sombor, where no infestation had been reported. At both locations twenty-one sugar beet varieties were planted. The selected varieties were provided from breeders distributing new selections in Serbia. At Kikinda beet root yield was 85.78 t/ha for Concerto variety and 12.00 t/ha for control variety (intolerant to disease). The obtained difference amounts to 73.78 t/ha or 86.01%. Difference in sugar content within the first-ranked variety Ivona (15.36%) and the control sample (10.91%) was 4.45% absolute. But, the established difference for crystalline sugar yield between the first-ranked variety Remos (9.205 t/ha) and the control variety (0.842 t/ha) amounted to 8.363 t/ha or 90.85%. At the other location, Sombor, extreme differences within varieties were also observed but to a lesser extent.
