Hybrid selection as a factor of increasing the yield and quality of sugar beet root
Adequate choice of hybrids is one of the most efficacious factors that can contribute to the improvement of the yield and quality of sugar beet root. To determine the production values of new hybrids of sugar beet resistant to leaf spot disease (Cercospora beticola Sacc.) and/or rhisomania (BNYVV), micro varietal trials were set up on the experimental field of the Faculty of Agriculture, Zagreb, in the period 2006-2008. The trials involved 34 sugar beet hybrids belonging to the five selection companies selling seed in the Republic of Croatia. The studied sugar beet hybrids differed significantly in root and sugar yields as well in sugar and soluble non-sugar concentrations. However, the results of a large number of hybrids were equal in value, since the differences were within statistically allowable deviation. In 2006, the hybrid Lavina gave the highest root yield (105.8 t/ha), Gazeta had the highest sugar content (15.47%), and the highest yield of pure sugar was obtained from Markus (13.18 t/ha) and Theodora (13.15 t/ha). In 2007, the highest root yield was given by the hybrid Amadea (109.4 t/ha), the highest sugar content by Markus (16.79%), and the highest sugar yield by Iris (14.83 t/ha). In 2008, the highest-yielding hybrid was Theodora (root yield 99.2 t/ha), the highest sugar contents were determined for Giraf (17.78%) and Tibor (17.75%), and the highest sugar yields were achieved with Theodora (13.21 t/ha), Karera (13.10 t/ha) and Amadea (13.09 t/ha).
