A: Additive effect of the QTL i.e. the contribution of one accession allele to the phenotypic variation. Values are shown with respect to the non-Col allele.
D: Dominance effect of the QTL i.e. the deviation of the heterozygote phenotype from that expected based on the additive effect. Values are shown with respect to the non-Col allele.
R2: Phenotypic variation explained by the QTL.
ns not significant.
Bold numbers are flowering time based on leaf number, rest are flowering time based on days to flowering measured when the inflorescence reached 3 cm
Shoulder on chromosome 4 QTL in Edi-0 population is associated with a high number of apparent double recombinants in the region – no clear candidate maps to this interval.
