Gene model for CLS resistance and susceptibility in the sour cherry using a 'Schattenmorelle' × 'Pc 2′ biparental population. One half of the progeny have the dominant allele for CLS-resistance R1 for the QTL CLSR_1f. The other half have the dominant allele for CLS-high susceptibility S1 for the QTL CLSS_1f. The Punnett square shows the obtained allele combination for the progeny. Under each allele combination, the means of crown defoliation scorings are depicted and the number of individuals is shown in brackets. The first value represents the marker combination 1F_25143168 (R) with 1A_30613785 (S) and the second value the combination CPSCT027 (R) with 1A_30613785 (S). Resistant individuals carry the R1 allele and showed a mean defoliation score of 3.8/3.7 (blue). Highly susceptible individuals carry the S1 allele and showed a mean defoliation of 5.8/5.9 (red). Moderate individuals carrying both dominant alleles R1 and S1 are depicted in green. The recessive alleles are depicted in white. Chi-square test revealed that the observed segregation for R1 fit a the expected 1:1 ratio.
