DescriptionA mapping population of 146 recombinant inbred lines (RILs) of the F9:10 generation derived from the cross of 'TG 26' with 'GPBD 4' were used to create a partial genetic linkage map composed of 45 SSR marker loci on 8 linkage groups. The total map distance is 657.90 cM and the average inter-marker distance is 14.62 cM. Linkage group lengths vary from 29.0 to 145.3 cM and the number of marker loci per linkage group ranges from 4 to 8.

CommentThe F9:10 population of 146 recombinant inbred lines (RILs) was developed from a cross of the peanut cultivars 'TG 26' with 'GPBD 4'. The F2 generation was progressed to the F9:10 by single seed descent. The authors screened 1043 SSR markers obtained from published sources on the parents and found 53 of the markers to be polymorphic. The 53 polymorphic SSR markers were then used to genotype the RIL population and 45 of those markers were located on the genetic linkage map.
