Abstract
Sugar beet is the most important crop for sugar production in Europe. Wide
genetic variability is essential in sugar beet breeding programs. The aim of
this study is to evaluate variability for the main root traits and
differences between monogerm and multigerm sugar beet genotypes from the
breeding collection at the Institute of Field and Vegetable Crops. The
following traits were analyzed: root weight (g), dry matter content (%), root
head weight (g), root/head ratio (%), number of cambial rings, root length
(cm) and root diameter (cm). Mean values for two years per genotype were
standardized and used for analysis. Principal Component Analysis (PCA) and
Cluster Analysis (CA) were used to examine the level of diversity for 20
genotypes and to rank the contributions of the variables. According to CA
genotypes could be placed into five main groups, where a large number of
multigerm genotypes were put in one group. On average multigerm genotypes
were characterized by higher mean values for root weight, length, diameter
and lower root head ratio. Multigerm genotypes had higher coefficients of
variation for nearly all measured root traits.
