Table 2 Genetic diversity within populations based on 37 SSR markers

From: High levels of nucleotide diversity and fast decline of linkage disequilibrium in rye (Secale cerealeL.) genes involved in frost response

Population No. of lines No. of private alleles a(%) Average no. of alleles (range) PIC b± SD Allelic richness c

  1. a Private alleles denotes the number of alleles which occurred only in one population.
  2. b PIC: Polymorphic information content, a higher value means higher genetic diversity.
  3. c Allelic richness is a measure of the number of alleles independent of sample size, a higher value means higher genetic diversity.
