title: [Construction of genetic linkage map for rubber tree (Hevea brasiliensis) based on SSR markers.].
abstract: Out of 260 polymorphic loci screened from a total of 441 pairs of EST-SSR and genomic-SSR primers, 176 were used for constructing the genetic map of rubber tree (Hevea brasiliensis) by an F1 segregating population including 94 progenies from the cross Reyan 88-13xIAN873. Chi-square test carried out on the polymorphic loci used in constructing the map showed that 147 loci followed a segregation ratio of 1:1 and 12 loci followed a ratio of 1:2:1 and 17 loci followed a ratio of 1:1:1:1. Only 13 (7.38%) loci were distorted from the Mendelian ratio. The genetic linkage map consisted of 91 marker loci in 18 linkage groups and covered 1 937.06 cM with an average genetic distance of 21.29 cM between adjacent markers. The largest linkage group consisted of 16 marker loci, while the smallest one contained only 2 marker loci.
