Determining paternity in polyploids: Hexaploid simulation studies

The breeding of new sweetpotato varieties is a highly inefficient process, confounded by incompatibility, poor fertility, open-pollination and hexaploidy. Upwards of 12–20 lines are combined in open pollinated nurseries based on horticulturally important characteristics. After several years of selection most progeny can be traced back to just 3 or 4 …

Microsatellite-based Paternity Analysis in Polyploid Sweetpotato

Using codominant molecular markers (microsatellites) for paternity identification was investigated in hexaploid sweetpotato [Ipomoea batatas (L.) Lam.]. Two experimental populations (CIP and LAES), each consisting of a progeny of known parentage, were scored for the presence or absence of alleles segregating at IB-316 and IB-318 microsatellite loci. Paternity was assessed …
