Table 4 Segregation of S-RNase alleles in controlled self-pollinations

From: Self-(in)compatibility in apricot germplasm is controlled by two major loci, S and M

Bebecou (S 6/S C) 0 (S 6/S 6) 33 (S 6/S C) 45 (S C/S C) 96 (78) 1.85 (0.17) 53.8 (0) n.d.d .

  1. aNumber of individuals from the self-progeny and total analyzed (between parentheses) are indicated
  2. bχ2 and (P) values for S-genotypes expected ratios considering a single mutation unlinked (1:2:1) or linked to the S-locus (1:1)
  3. cχ2 and (P) values for PGS3.23 (in ‘Corbató’ self-progeny) and AGS.20 (in ‘Portici’ self-progeny) genotypes expected ratios considering a single mutation located at the M-locus (1:1). No homozygote for the SSR-allele in repulsion-phase linkage with the m 0-haplotype was detected in either case. [n] indicates number of individuals tested
  4. dn.d. Not determined
