Summary: | The producing values of monogerm CMS lines of sugar beet and their tolerance on cercospora leaf spot are
investigated in Osijek during two years (2001, 2002) under the following conditions: natural infection and full
protection with fungicides. The parameters for evaluation were root quality and yield, just as visual review of
leaf damages. Twenty eight genetically divergent CMS lines and two standards were confirmed by the
examinations. The test results indicate achieved progress in breeding and monogerm CMS lines value which
can be used for obtaining new hybrids and further improvements. Three investigated lines achieved high root
yield on the level of standards and even ten lines had the same or higher digestion than better standard. It was
found out that in the case of fungicide apply, root yield increased on the average by 7.09 t/ha (16%), sugar
content by 0.81% (rel. 5%) and sugar yield by 1.38 t/ha (22.8%). Protection measures with fungicides had
higher influence on production results of line being susceptible to cercospora and compared to cercospora
tolerant lines. |
