Fig. 3From: Identification of a cold-tolerant locus in rice (Oryza sativa L.) using bulked segregant analysis with a next-generation sequencing strategyIdentification of the hot-region for PSST through the SNP-index association analysis method. X-axis represents the position of 12 chromosomes of rice and Y-axis represents the SNP-index or Δ (SNP-index). The color dots represent the SNP-index or Δ (SNP-index) value of every SNP locus. The black lines show the SNP-index or Δ (SNP-index) value of fitting results. a: the SNP-index graph of T-pool. b: the SNP-index graph of S-pool. c: the Δ (SNP-index) graph. The red dotted line shows the association threshold value (0.9532)Back to article page
