Abstract

Two monogerm hybrids of sugar beet of the Institute for sugar beet Osijek were recognized by the Variety commision of the Ministry of Agriculture and Forestry of the Republic of Croatia in 1998. Newly recognized hybrids named lva and Kaja thereby had privilege to be registered in the list of recognized newly established varietics of agricultural plants in the Republic of Croatia. Triploid sugar beet hybrid lva achieved root yield of 67.7 t/ha in the experiments of the Variety commision from 1995-1997. lt was more than standard hybrids Os Nada and Astro. The achieved sugar content (14.97%) was slightly higher than the standard whereas sugar utilization ( 12.59o/o) was considerably higher than the standard. The higher utilization is characterized by especially lower root amino acid and potassium content of the new hybrid. Hybrid of sugar beet lva achieved pure sugar yield of 8.61 t/ha in the three year investigation which is by 850 kg/ha higher than the standard. New triploid sugar beet hybrid Kaja achieved, in the Variety commision experiments, root yield of 65.6 t/ha, digestion of 15.43o/o, sugar utilization of 13.11% and pure sugar beet content of 8.64 t/ha which is by 880 kg/ha higher than the standard, All indicators are better than the results obtained by a standard cultivar. Good quality properties of this hybrid are indicated by especially higher digestion and lower content of analysed molasses-forming matters.
