F1020, PI 656593
subsp. vulgaris cv. Sugar beet
Male sterile plants of a California breeding line, 3747, were pollinated with pollen from 50 plants representing 8 wild B. vulgaris ssp. maritima accessions originally collected in the Middle East.
F1020 was developed with the intent of introducing diversity into the narrow genetic base of the commercial sugarbeet crop. Roots of F1020 have white skin and flesh. Hypocotyls of F1020 are green. F1020 is a multigerm diploid line. Six-year average root yields were 55% of an adapted commercial hybrid sucrose concentrations averaged 19 g/kg less than the commercial hybrid. Preliminary screenings indicate F1020 is susceptible to Rhizoctonia root and crown rot (Rhizoctonia solani K hn) and rhizomania (Beet necrotic yellow vein virus) with an indication that F1020 has some resistance to Cersospora leaf spot (Cercospora beticola Sacc.) and Aphanomyces root rot ( Aphanomyces cochlioides Drecsh).
