TABLE 2.
Loss of B. carinata C alleles in the KCN-10 mapping populations: the percentage of loci on each linkage group having one C-genome allele from the B. carinata parent, at each backcross generation
| Generation (% expected) | N11 | N12 | N13 | N14 | N15 | N16 | N17 | N18 | N19 | Mean |
|---|---|---|---|---|---|---|---|---|---|---|
| KCN-10-F1, 1 individual, no. of markers used | 15 | 8 | 15 | 14 | 5 | 4 | 11 | 8 | 7 | 10.3 |
| KCN-10-BC1, 6 individuals, % loci with B. carinata alleles (50%) | 28 | 27 | 43 | 40 | 40 | 37.5 | 51 | 35 | 42 | 38 |
| KCN-10-BC2, 5 individuals, % loci with B. carinata alleles (25%) | 16 | 5 | 24 | 18 | 40 | 20 | 25 | 20 | 22 | 20.5 |
| KCN-10-BC3, 88 individuals, no. of alleles present | 4 | 0 | 2 | 1 | 0 | 1 | 3 | 2 | 2 | 2.3 |
The percentages of lines that had inherited B. carinata C alleles in the BC1, BC2, and BC3 generations of the KCN-10 population are shown. Percentages are calculated on the basis of the number of loci where B. carinata C-genome alleles were detected for each C-genome linkage group, present at each generation, F1 plants behaved normally, and the polymorphic SSR markers had one B. napus and one B. carinata allele.
