Description
We performed quantitative trait locus (QTL) analysis for cold tolerance at the booting stage (CT), heading date (HD) and culm length (CL) using 84 recombinant inbred lines derived from a cross combination between temperate japonicas Hokkai-PL9 (cold-tolerant) and Hokkai287 (cold-sensitive). CT was evaluated by fertility after cold water treatment. Three QTLs for CT were detected on chromosomes 1 (qCTB1.1 and qCTB1.2) and 8 (qCTB8.1), and Hokkai-PL9 allele at all three QTLs increased the level of CT. Phenotypic variance explained (PVE) of qCTB1.1, qCTB1.2 and qCTB8.1 were 18.8%, 11.8% and 14.2%, respectively. Three QTLs for HD were detected on chromosomes 2 and 3 (two QTLs), and nine QTLs for CL were detected on chromosomes 1, 2, 3 (three QTLs), 8, 9 (two QTLs) and 11. No QTLs for HD and CL were detected in the same region as QTLs for CT. The effects of the Hokkai-PL9 allele of QTLs for CT significantly increased CT, suggesting that QTL combination is effective for CT improvement.<br>
