Segregation of the <i>S-RNase</i> 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 P<0.05 (barring ‘Katy’ self-pollination at P>0.01).
