The segregation ratios of the combined genotypic classes for the markers on PEAR3 LG5 and on ‘Moonglow’ LG1 are compared between ‘Type 1’ and ‘Type 2’ + ‘Type 3’ progeny. The segregation ratios of the genotypic classes for the marker on PEAR3 LG2 are compared between ‘Type 2’ and ‘Type 3’ progeny. The results of the X² test, the degrees of freedom (df) and the ρ values are shown. At ρ > 0.05, the observed segregation ratios are significantly distorted. The incompatible genotypes are underlined.
