Mapping mutants of classical linkage groups 6 and 8 (CLGs 6 and 8) in soybean [Glycine max (L.) Merr.] can enhance the identification of important agronomic traits. Genetic data suggest that CLGs 6 and 8 may belong to the same linkage group. Our objectives were to determine if CLGs 6 and 8 are the same or different linkage groups and to determine the gene order. Genotypes containing mutants of CLGs 6 and 8 and mutants of other CLGs were crossed in various combinations. Data for the different characters were collected from F₂ populations and F_2:3 families. Recombination values confirmed that CLG 6 characters, Df₂ and Y₁₁ were linked (R = 27.0 ± 5.9), Df₂ was linked to Ms₁ (CLG 8) (R = 24.8 ± 1.2) and to W₁ (CLG 8) (R = 36.4 ± 1.3), and Y₁₁ was linked to Ms₁ (R = 31.7 ± 1.4). F₂ data suggested that Y₁₁ segregated independently of W₁, while F_2:3 data indicated the two were linked (R = 38.4 ± 3.2). Our data indicated that CLGs 6 and 8 belong to the same linkage group, which is molecular linkage group F (MLG F), and chromosome 13. Y₁₁ and Adh₁ are at the ends of the chromosome segment studied, and Y₂₃ is located between Ms₆ and St₅. Recombination values among the other loci of CLG 8, and between them and loci of other CLGs were consistent with published values. This information will be useful in the reassignment of CLGs, ordering of loci, and will enhance molecular genetic linkage mapping in soybean.
