Male sterile plants of a California breeding line, 3747, were pollinated with pollen from 119 plants representing 11 wild B. macrocarpa accessions.

F1022 was developed with the intent of introducing diversity into the narrow genetic base of the commercial sugarbeet crop. Roots of F1022 have white skin and flesh. Hypocotyls of F1022 are green. F1022 is a multigerm diploid line. Six-year average root yields were 58% of an adapted commercial hybrid sucrose concentrations averaged 27 g/kg less than the commercial hybrid. Preliminary screenings indicate F1022 is some resistance to Rhizoctonia root and crown rot (Rhizoctonia solani K hn) and is susceptible to rhizomania (Beet necrotic yellow vein virus), Cersospora leaf spot (Cercospora beticola Sacc.), and Aphanomyces root rot ( Aphanomyces cochlioides Drecsh).
