| Project type |
QTL |
| Description |
Quantitative trait locus (QTL) analysis was conducted in two F1 progenies derived from crosses between the cultivars Fiesta and either Discovery or Prima. Both progenies were inoculated in the greenhouse with the same strain of E. amylovora, and the length of necrosis was scored 7 days
and 14 days after inoculation. Additive QTLs were
identified using the MAPQTL software, and digenic epistatic
interactions, which are an indication of putative
epistatic QTLs, were detected by two-way analyses of
variance. A major QTL explaining 34.3–46.6% of the
phenotypic variation was identified on linkage group
(LG) 7 of Fiesta in both progenies at the same genetic
position. Four minor QTLs were also identified on LGs
3, 12 and 13. In addition, several significant digenic
interactions were identified in both progenies. |
