Characterization of Canopy Temperature in Bread Wheat Genotypes under Terminal Heat Stress
Canopy temperature (CT) is one of the important traits for evaluation/screening for high temperature tolerance in wheat crop. In our study genotypes are sowing variation in terms of canopy temperature. The ten wheat genotypes were assessed during the 2021–2022 rabi season using a precise phenotyping technique under both timely sown (TS) and late sown (LS) conditions. 7th day after anthesis (DAA), PBW644 showed the highest value 39.60C and PBW752 showed lowest value 31.1 °C in TS condition. DBW14 (Delhi bread wheat) showed the highest value 51.5 °C and PBW757(Punjab Bread Wheat) showed the lowest value 37.0 °C in LS condition. 14th DAA, AKW1071 (Akola wheat) showed highest value 40.4 °C and PBW752 showed lowest value 32.2 °C in TS condition. PBW644 showed highest value 48.5 °C and DBW71 showed lowest value 37.1 °C in LS condition. High canopy temperature implies reduced heat tolerance or sensitivity to high temperatures or limited moisture. Low canopy temperature suggests better adaptation to heat or drought conditions, possibly due to traits like increased transpiration rates or better water use efficiency.
