An investigation of genotype-phenotype association in a festulolium forage grass population containing genome-spanning <i>Festuca pratensis</i> chromosome segments in a <i>Lolium perenne</i> background - Fig 3

A. Relative variation in tiller number within S4fam represented according to the position of the introgressed F. pratensis chromosome segment. Each column in each graph is the mean of the trait score for the genotypes within S4fam which contain a F. pratensis introgression at that particular position (illustrated below the x axis). For each illustration of the pattern of F. pratensis introgressions, each row represents a single genotype and each column a defined and sequential region of the chromosome from end to end. A red square indicates a F. pratensis introgression at that relative position in that particular genotype; a green square indicates the L. perenne background. Error bars are standard errors (nB. Spearman rank correlation significance levels for individual genotype tillering scores in S4fam from the 9 trials described in Fig 3A. Numbers refer to the numbering in Fig 3A.
