“…If there was no genetic linkage between the resistance to Ls1 and the resistance to Lw023 in this hybrid population, the resistance to Lw023 of the 73 Ls1‐resistant plants (Table ) should have segregated as a resistant to susceptible plants ratio of 1 : 15, according to our previous analysis (Liu et al. ). If all the Ls1 resistance loci also conferred resistance to Lw023, then all the 73 Ls1‐resistant plants would be expected to be resistant to Lw023.…”

“…The spacing between seedlings was 0.5 × 2.0 m. In 2008 and 2009, bot canker susceptibility was phenotyped by in vivo inoculation in the field and phenotyping for FRR resistance was performed under room conditions using the mycelia of five isolates of B. dothidea (Ls1, Lw023, Lw048, Mx1 and Zz26; Liu et al. ; Zhuang et al. ).…”

“…When the stems of apple hybrids were inoculated with the intermediate pathogenic B. dothidea isolate Lw048, the gene loci of the host conferred dominant resistance in the first year, that is, in 2008; however, in 2009, the same host gene loci conferred recessive resistance (Liu et al. ).…”

“…We previously reported the segregation of four independent loci that segregate in the cross Jonathan × Golden Delicious that are involved in the inheritance of resistance to five isolates of bot canker (Liu et al. ). The variation in susceptibility to FRR in this population was attributed to the segregation of three major gene loci for each pathogen isolate; some of the loci conferring resistance to isolates Ls1, Mx1 and Lw048 were mapped onto four linkage groups (Zhuang et al.…”

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. None of the QTLs for bot canker and FRR overlapped with the region of the major gene loci. Some of the FRR‐ and bot canker‐associated loci either coincided or overlapped, and some were independent, suggesting that the responses of different organs to the pathogen would be correlated but might deviate from each other. Some major gene loci and QTLs associated with different pathogen isolates of bot canker or, FRR were mapped to different regions of the genome. The results indicated that not only did the resistance mechanisms differ between bot canker and FRR but also that genetic differentiation occurred among pathogen isolates.

To analyse the inheritance of fruit ring rot (FRR) resistance and to screen for microsatellite markers linked to resistance⁄susceptibility, 875 apple hybrid seedlings (Malus domestica, Jonathan · Golden Delicious) were inoculated with five isolates of Botryosphaeria dothidea in 2 years (2008 and 2009). The results indicated that incidence and non-incidence were qualitatively segregated, and incidence was dominant to non-incidence. The variation in susceptibility within this population was attributed to the segregation of three major genes. For the phenotype of incidence, the severity of lesion development was a quantitative trait. From 230 published microsatellite primer pairs, six markers were identified that were linked to the susceptibility to FRR. located in LG12 and LG2, respectively, were linked to susceptibility to the pathogen isolate Mx1, and their map distances to the susceptibility loci were 8.2 and 5.1 centimorgan (cM), respectively. CH01e01-120 and CH02c02b-100, which were linked to susceptibility to Ls1, were located in LG14 and LG4, and the map distances to the susceptibility loci were 16.9 and 8.4 cM, respectively. CH05d11-150 and CH03a03-230, linked to susceptibility to Lw048, were located in LG12 and LG14; for both of them, the map distance was 13.4 cM.
