Description |
In this study, a segregating population derived from a cross between the wild apple species Malus fusca and the M. x domestica cultivar Idared was explored. F1 progenies used for mapping were artificially inoculated with Erwinia amylovora strain Ea222_JKI at a concentration of 109 cfu/ml in three different years. The averages of
percentage lesion length of all replicates of each genotype were used as numerical traits for statistical
analysis. A Kruskal–Wallis analysis was used to determine marker–phenotype association and revealed
a linkage group with Diversity Arrays Technology (DArT) markers significantly linked with fire blight.
After locating the positions of the DArT markers on the Golden Delicious genome, simple sequence repeat
(SSR) markers were developed from chromosome 10 to replace the DArT markers and to determine the
quantitative trait locus (QTL) region. |
