  1. 1Marker are considered scorable when they produced amplicons of less than 500 base pairs
  2. 2 EST-SSRs classified as polymorphic by PolySSR; 3 EST-SSRs classified as monomorphic by PolySSR; along SSRs: at least 10 repeats in repeat motif for dinucleotide SSRs, 6 for tri-SSRs, 5 for tetra-, penta- and hexa-SSRs; bshort SSRs: at most 5 repeats for dinucleotide SSRs, 4 for tri-, tetra-, penta- and hexa-SSRs (see Materials and Methods).
