New approaches for mapping ppv (plum pox virus) resistance in apricot (prunus armeniaca)

In this study, we have mapped the PPV (Plum pox virus) resistance trait as a QTL using a non-parametric mapping method based on the Kruskal-Wallis test. To increase the reliability of this analysis new SSR markers from apricot and peach were incorporated to the F2 ‘L×L’ linkage map derived from a s...

Summary:In this study, we have mapped the PPV (Plum pox virus) resistance trait as a QTL using a non-parametric mapping method based on the Kruskal-Wallis test. To increase the reliability of this analysis new SSR markers from apricot and peach were incorporated to the F2 ‘L×L’ linkage map derived from a self-pollination of the resistant cultivar ‘Lito’. Several tightly linked AFLP markers, located at the upper region of the linkage group 1, showed high significance levels of the Kruskal-Wallis test statistic, indicating the presence of a putative QTL for the PPV resistance trait.
