SNP-index graphs of HSB, HTB, and ∆(SNP-index) graphs from QTL-seq analysis. X-axis denotes the position (Mb) of 12 chromosomes of tomato and Y-axis represents the SNP-index of HSB (Heat-sensitive bulk), HTB (Heat-tolerant bulk) and ΔSNP-index of HTB-HSB. SNP-index was estimated based on 1 Mb physical interval with a 10 kb sliding window. Using the statistical confidence intervals under the null hypothesis of no QTL (P < 0.01), the Δ(SNP-index) graph was plotted. 12 QTLs were identified on chromosome 1, 2 and 7 (1–2 Mb interval) with the criteria that the SNP-index near to 0 and 1 in HSB and HTB, respectively, and the Δ(SNP-index) was above the confidence value 0.5 (at significance level P < 0.01)
