DescriptionA genetic map was created based on an F6 RIL population derived by single seed descent from the cross of the Rust-susceptible maternal (ovule) parent Arachis ipaensis GKBSPSc 30076 (abbrev. K30076) with the Rust-resistant paternal (pollen) parent Arachis magna GKSSc 30097 (abbrev. K30097). This 94-member F6 population was derived by single seed descent from an F2 population described by Moretzsohn, Barbosa et al. (2009a). An earlier version of a genetic map for this same F6 RIL population appeared in Shirasawa, Bertioli et al. (2013a) [798 marker loci, 461 cM]. A map had also been developed using the F2 population in Moretzsohn, Barbosa et al. (2009a) [149 marker loci, 1294 cM total length]. The total length of the genetic map is estimated to be 678.2 cM and the average inter-marker distance is 1.7 cM. The map includes 378 microsatellite and 21 transposon (miniature inverted-repeat transposable element) markers that comprise a total of 399 genetic markers. The map is composed of 10 linkage groups that are labeled and oriented as shown in Moretzsohn, Barbosa et al. (2009a) with the exception of the flipped B05 and B08. The linkage groups range in size from 41.5 cM to 139.2 cM, which are composed of 35 and 55 markers, respectively.

CommentDiscrepancies in the genetic map sizes observed among Moretzsohn, Barbosa et al. (2009a); Shirasawa, Bertioli et al. (2013a); and Leal-Bertioli, Cavalcante et al. (2015a) are likely the result of different software packages and the variant ways in which they handled genotyping errors.
