Technical Abstract: Sugarbeet (Beta vulgaris) is believed to have a narrow genetic base. The wild progenitor of all cultivated beets, B. vulgaris subsp. maritima, has a wider base. In recent years, a concerted effort has been made by sugarbeet researchers to identify and characterize useful traits in the wild species and to prebreed sugarbeet x wild beet populations. The released lines C26, ,C27, and C51 are prebred sugarbeet x wild beet breeding lines developed at Salinas that should make the genetic variability in the wild types more accessible to plant breeders. C26, C27, and C51 have been specifically selected for high resistance to the soil-borne disease rhizomania. In addition, they appear to have resistance to other diseases and pests. These enhanced, broadly based, germplasm lines may offer new sources of genetic variability for the future improvement of sugarbeet.
