Interpretive Summary:

Technical Abstract: EL53 sugarbeet germplasm is substantially derived from previously released smooth-rooted, low soil tare germplasm releases with two additional cycles of selection for freedom from Rhizoctonia crown and root rot disease. Previous low soil tare releases have been uniformly susceptible to Rhizoctonia crown and root rot. The moderately resistant germplasm EL52 was used as a source of resistance during the development of EL53. EL53 is diploid, self-sterile with predominantly red hypocotyls and segregates for monogerm seed type as well as the smooth-root trait. EL53 has a complex pedigree involving seven previously released smooth-root germplasms, two unreleased smooth-root breeding populations, and three traditional East Lansing germplasm releases. EL53 has shown good agronomic performance, and it is expected to be a resource for developing low soil tare parental lines for hybrid cultivars with economically recoverable levels of sucrose
