Introgression lines (ILs) phenotyped and used as parents to generate double-introgression lines.

Accession identifiers from the Tomato Genome Resource Center (tgrc.ucdavis.edu). QTL: Prior evidence of IL carrying QTL for pollen sterility (P), seed sterility (S) or none (N). Chr: Chromosomal location of the introgression (out of 12 chromosomes in the lyc genome). Size: length of introgressed region, as a percentage of the lyc genome. Seed: Sample size (N), mean (and standard deviation) for self-seed count (SSC) and pollen-corrected seed fertility (SF). Pollen: Sample size (N), mean (and standard deviation) for proportion of fertile pollen (PF). P-values are from normal and quasi-likelihood binomial general linear models (for seed and pollen, respectively). (*) The IL has a significant individual effect on the corresponding phenotype.
