Narrative
R40 is a multigerm (MM), self-sterile (Ss), open-pollinated line that maintains sugar and root yields under both the wild-type (Type A) and Rz1 resistance-breaking (Type-A, IV) strains of BNYVV. It is a product of repeated rounds of recurrent selection on enhanced, broadly based populations of over 120 Beta vulgaris subsp. maritima accessions (selected for rhizomania resistance) crossed with sugar beet. This broadly-based germplasm provides useful genetic variability for continued sugar beet improvement.

Pedigree
Description:
During development of R40, rhizomania resistant plants from a composite of C79-1 through C79-11 were selected from field trials and increased by open-pollination. Seed was collected in bulk and planted in the next year’s field trials. Three rounds of recurrent selection were performed on this germplasm, selecting plants with resistance to the wild-type (Type A) and Rz1 resistance-breaking (Type-A, IV) strains of BNYVV. The final round of recurrent selection and increase produced R40.
