Narrative
FC1740 is a diploid, multigerm sugar beet populations in normal cytoplasm, segregating for self-sterility (Sf:SsSs) and hypocotyl color (R:rr). This germplasm has good resistance to rhizomania (Beet necrotic yellow vein virus) and was selected as homozygous resistant to markers linked to both Rz1 and Rz2 genes for resistance. FC1740 has shown good resistance to beet curly top (Beet curly top virus), not different from the resistant control in 2 years of testing and although significantly less resistant than the resistant control in 2 other years, still more resistant than the susceptible control. It has shown excellent resistance to fusarium yellows (Fusarium oxysporum f. sp. betae and other Fusarium species), not significantly different from the resistant control in 2 years of testing. In two years of testing it was moderately resistant to aphanomyces root rot (Aphanomyces cochlioides Drechs.), significantly more susceptible than the resistant control and significantly more resistant than the susceptible control. FC1740 did not exhibit resistance when challenged by cercospora leaf spot (Cercospora beticola Sacc.), rhizoctonia crown and root rot (Rhizoctonia solani Kühn) or sugar beet root aphid (Pemphigus sp.). This germplasm provide a source from which to select disease-resistant, multigerm pollinator parents, with either or both of the Rz1 and Rz2 sources of rhizomania resistance. Because it is from the same original population as FC1741, FC1742, and FC1743 it will be useful as a control of known genetic background in comparing entries being screened for rhizomania resistance.

Pedigree
Description:
FC1740 was selected from a polycross of C79-1, C79-2 … C79-11 (PI 593660 through PI 593670) with C37(PI 590715), having different sources of resistance to Beet necrotic yellow vein virus (BNYVV) (rhizomania).There was cyclic selection for resistance to rhizomania – both BNYVV and the resistance-breaking strain –percent sucrose and yield (weight). FC1740 was based on 210 vegetative plants selected that had Rz1 andRz2 SNP markers homozygous resistant (inferred genotype – Rz1Rz1Rz2Rz2.
