Sugar beet production on infected soil by the BNYVV virus using tolerant hybrids

Rhizomania is the most prevalent and the most harmful sugar beet disease, but nowadays does not account for serious threat to production owing to the advancement in plant breeding. Investigations were carried out to determine genetic potential of fertility of tolerant hybrids on both, health soil, and soil infected with BNYVV virus. The trials were set up on Eutric Cambisols, on the plot with no BNYVV viruse detected, and on the plot infected with the virus. We used 10 tolerant and 2 sensitive hybrids during three year-investigations. On the basis of the triennial results all investigated parameters of sugar beet yield and quality on infected soil were found to be significantly higher (p<0.01) in hybrids tolerant to rhizomania relative to the sensitive hybrids. The differences between the hybrids obtained on health soil were exclusively result of genetic diversity between the hybrids.
