F1023, PI 656595
subsp. vulgaris cv. Sugar beet
Male sterile plants of a California breeding line, 3747, were pollinated with pollen from 31 plants representing 3 wild B. patula accessions.
F1023 was developed with the intent of introducing diversity into the narrow genetic base of the commercial sugarbeet crop. Roots of F1023 have white skin and flesh. F1023 is segregating for green and red hypocotyl color. F1023 is a multigerm diploid line. Six-year average root yields were 73% of an adapted commercial hybrid sucrose concentrations averaged 22 g/kg less than the commercial hybrid. Preliminary screenings indicate F1023 is susceptible to Rhizoctonia root and crown rot (Rhizoctonia solani K hn), rhizomania (Beet necrotic yellow vein virus), and Cersospora leaf spot (Cercospora beticola Sacc.), and may have some resistance to Aphanomyces root rot ( Aphanomyces cochlioides Drecsh).
