Abstract

Sugar beets are grown because of root that is used for sugar production. The yield of technological sugar is a result of root yield, sugar content and utilization of sugar. On the utilization of sugar, a significant effects have a conent of sodium, potassium and "harmful" nitrogen. By the individual analyses, we determine a content of sugar, sodium, potassium and "harmful" nitrogen of the individual sugar beet rots. The utilization of sugar per beet is very practical property in the selection of roots, because it combines conent of sugar, sodium, potassium and "harmful" nitrogen. With the increasing of root mass up to 800 g, the content of sugar increases, and later decreases. Similar situation is with the utilization of sugar. The content of potassium, sodium and "harmful" nitrogen increases with the increasing of root mass. On the yield of technological sugar, the most influence has root mass. With the increasing of root mass, the yield of technological sugar is increasing also. The final selection is on the basis of the root shape. The regular and conical shape of root with the low head and the shallow longitudinal furrows is required. On the basis of results, the roots are divided in the three groups: the mother roots, the super-elite roots, the elite roots, and the worst roots are discarded.
