From: Characterization of and genetic variation for tomato seed thermo-inhibition and thermo-dormancy
Genomic location of QTLs detected for thermo-tolerance, thermo-inhibition and thermo-dormancy of a Solanum lycopersicum and Solanum pimpinellifolium RIL population. The 12 chromosomes of tomato are separated by white lines. Centimorgan positions increase from left to right. 37 °C, 25 °C and GA represent germination at 37 °C (thermo-tolerance), 25 °C (thermo-inhibition) and 25 °C after GA and stratification treatments (thermo-dormancy), respectively. Colours across the chromosomes display significant QTLs (P = 0.05) based on the LOD colour scheme in which green and blue represent a larger effect of S. pimpinellifolium (PI) alleles on the traits and yellow and red of the S. lycopersicum (MM) alleles
