Figure 2From: High levels of nucleotide diversity and fast decline of linkage disequilibrium in rye (Secale cerealeL.) genes involved in frost responsePrincipal co-ordinate analysis of 201 rye lines from five populations (PR, EKO, SMH, ROM, Petkus) based on candidate gene haplotypes. Analysis was based on a similarity matrix of candidate gene haplotypes. PCo1 and PCo2 are the first and second principal co-ordinates and percentages indicate percent variation explained.Back to article page
