Molecular mapping of high temperature tolerance in bread wheat adapted to the Eastern Gangetic Plain region of India.

Highlights: [•] The inheritance of tolerance to high temperature stress was investigated using QTL analysis on a doubled haploid population. [•] Seven stable QTL were identified for HSI of traits, mapping to chromosomes 1D, 6B, 2D and 7A. [•] Three QTLs related to HSI of grain filling duration, two to thousand grain weights and one each to grain yield and canopy temperature. [•] The QTL analysis for the direct traits GY, TGW, GFD and CT led to detection of 22 QTLs spread over to 17 chromosomal regions. [•] A QTL for TGW on chromosome 6B under normal sown co-located with HSI (TGW) QTL QHTgw.bhu-6BL. [Copyright &y& Elsevier]
