  1. A. Average data for quantitative traits with QTL displaying significant differences (P > 0.05) between homozygous and heterozygous individuals for linked markers in BC populations. Major QTL (R2> 25%) are indicated in bold. Data traits with significant differences are indicated in bold. B. Frequency for the different categories for qualitative traits with QTL displaying significant differences between homozygous and heterozygous individuals for linked markers in BC populations and results of the Fisher exact test. Data traits with significant differences are indicated in bold.
  2. 1 Tested markers located in the QTL region (see Figures 2, 3, 4, 5 and 6).
  3. 2 Homozygotes for the Zucchini allele of the corresponding marker in BCZ are indicated as a (allele from MU-CU-16), while heterozygotes are indicated as h.
  4. 3 Homozygotes for the Scallop allele of the corresponding marker in BCS are indicated as b (allele from UPV-196), while heterozygotes are indicated as h.
  5. 4 Only the categories represented in the BC populations are included.
  6. 5 Fisher's exact probability test. P (α = 0.05). P < 0.05 implies association and linkage with the marker, as H0 of independence is rejected (†).
