Segregation of the S-RNase alleles in progenies of self-pollinations and outcrosses performed with the self-compatible cultivar ‘Katy’.

Observed S-RNase genotypes, expected segregation ratios and χ2 values obtained for each population are indicated.aS-genotypes for ‘Goldrich’, ‘Harcot’ and ‘Canino’ were prevously reported by Vilanova et al. (2005) and the S-genotype for ‘Katy’ was determined in this work.b‘K×K’ data correspond to three combined F2 populations obtained by self-pollinating ‘Katy’ in 2005, 2006 and 2010.cObtained seedlings.dExpected ratios for a single mutation unlinked to the S-locus.eObserved ratios do not differ significantly from expected at P0.01).
