  • a QTL acronym reflects the PC for which it was detected (first number) and the chromosome where it was located (second number).

  • b The map location of these markers can be found on the Solanaceae Genomics Network Web site (http://www.sgn.cornell.edu).

  • c An asterisk indicates a significant additive effect. A negative value indicates that an increase in the value of the attribute is due to S. pimpinellifolium allele, and a positive value indicates that an increase in the value of the trait is due to S. lycopersicum allele.

  • d An asterisk indicates a significant dominant effect. A negative value indicates that the S. pimpinellifolium allele is dominant and a positive value indicates that the S. lycopersicum allele is dominant.
