Multi-trait QTL analysis in heterokaryon Set 1. The two color scales of the bars indicate the two parents contributing high value allele of QTLs. The variation in blue (varying from dark blue to light blue) represents alleles from Mes09143 and the darker the color the higher the effect of the QTL. Similar for the variation in red (varying from red to yellow) that represents the high value alleles from H97. Green bars at the top indicate chromosomes bearing QTL with significant effects. The significance of the QTL were indicated above the figure in the value of “−log₁₀(p)”. The different widths of linkage groups reflect the different map lengths of the corresponding chromosomes and represent thus the recombination frequency of markers on each chromosome. It shows that chromosome 8 has the highest frequency of recombination of all chromosomes
