||Apple fruit ring rot and bot canker resistance-Han-2014
||Infection by the globally distributed pathogenic fungus Botryosphaeria dothidea (Moug.) Ces. et de Not. causes bot canker on the stems, branches and limbs or causes fruit ring rot (FRR) on the fruit in apple. To investigate the relationship between resistance to bot canker and FRR and among resistance mechanisms in response to different pathogen isolates, 34 major gene loci and six quantitative trait loci (QTLs) for bot canker and FRR resistance/susceptibility were genetically mapped on Malus genome using an F1 hybrid population (Jonathan × Golden Delicious) in 2008 and 2009.
This project contains 6 QTL:
