“…Eileen et al [15] found two of hundred SSR loci linked to tomato colour were co-segregated with expected pattern 1:2:1 at F 2 generation. Similar pattern was also achieved at F 2 generation by Cregan et al [16], while looking at linkage analysis of markers in soyabean. In the present study, an identical co-segregation ratio was achieved at F 1 generation (1:1) which implies that it is a reliable marker which can be employed efficiently in identification and classification of resistant cultivars.…”

With the discovery of molecular markers and marker assisted selection technology, the research has entered into a new era and has made it possible to develop new and more informative PCR-based markers, including SSR, and to further facilitate the use of markers in tomato breeding. The present study is a step to introduce a new SSR marker (TOM-144) which was deduced after evaluation of eight microsatellite loci amongst the twenty-one different tomato cultivars. The marker selected was inherited and segregated in mendelian fashion as demonstrated in successive generation of a cross between parent cvs. H-24 x GT-2.

“…In order to provide a high level of SSR length polymorphism, each of the primary trisomics are being crossed with Glycine soja PI 407287. PI 407287 is a vigorous genotype that produces completely fertile hybrids with cultivated soybean (Cregan et al, 1989). Crosses of PI 407287 have been made to each of the 20 primary trisomics.…”

Primary Trisomics and SSR Markers as Tools to Associate Chromosomes with Linkage Groups in Soybean

Primary trisomics provide an excellent cytogenetic tool to associate genes and linkage groups with their respective chromosomes. A complete set of 20 primary trisomics (2x + 1 = 41) has been established in soybean [Glycine max (L.) Merr.]. A linkage map of soybean with 20 consensus linkage groups has recently been defined. Because simple sequence repeat (SSR) markers map to defined single positions in the soybean genome, the association of a SSR locus with a chromosome will provide an unambiguous association of a linkage group to a specific chromosome. The objective of this work was to demonstrate the use of SSR markers to associate linkage groups with chromosomes by means of primary trisomics. One population of F2 plants was developed from an F1 hybrid trisomic for chromosome 13 (Triplo 13) and a second F2 population was obtained from a F1 hybrid trisomic for chromosome 5 (Triplo 5). Polymorphic SSR markers from different consensus linkage groups were tested on a subset of 20 plants from each population to identify markers that appeared to show segregation that deviated from normal (1:2:1) disomic inheritance. Markers not associated with the specific chromosome segregated in a disomic (1:2:1) fashion. Markers identified in this manner were further examined in the complete population of F2 plants to identify those that demonstrated trisomic segregation (6:11:1). By this approach, Triplo 13 was associated with linkage group F and Triplo 5 with linkage group A1. This result was verified by the examination of seven SSR loci on linkage group F and eight loci from linkage group A1 with each showing trisomic segregation with the Triplo 13‐ and Triplo 5‐derived F2 populations, respectively. These results demonstrate the first association of molecular linkage groups with chromosomes in soybean and indicate that SSR markers provide a tool to associate the remaining 18 trisomics with their respective linkage groups.
