| Curly top of sugarbeet is caused by Beet severe curly top virus (BSCTV) or closely related curtovirus species which are vectored by the beet leafhopper (Circulifer tenellus). Beta corolliflora, shown in 1969 to impart a very high level of curly top resistance to sugarbeet into the BC2 generation, is a wild relative of cultivated sugarbeet that has not been utilized in breeding programs. The nature of curly top resistance from B. corolliflora seems to be reduced symptoms and resistance to viral accumulation. Field screening of 14 B. corolliflora accessions for resistance to curly top followed by PCR detection of BSCTV did not identify any accessions with phenotypic symptoms of curly top and 9 accessions did not have detectable virus.
