Thermotolerance evaluation of NTRs and ATRs at seedling stage and the expression levels of HSP101 under heat stress in NTR. a, b, c The expression levels of HSP101 in response to heat stress in leaf, leaf sheath and root of NTR, Huaduo 1, at seedling stage. d The growth of seedlings under high temperature in neo-tetraploid rice lines (Huaduo 1 and Huaduo 2543), indica (Huanghuazhan and Huanghuazhan-4x), japonica (Taichuang65 and Taichuang65-4x) and NTR parental lines as controls. The scale bar indicates 1 cm. (e, f) Heat sensitivity index of seedling length and root length of all tested lines
