Abstract:

An experiment was conducted with wheat genotypes Halna, PBW-343, Raj-3765, K-9006, HD-2733, K-8962, NW-1014, NW-1067, UP-2338 and DBW-14 to evaluate heat tolerant in wheat at instructional farm and in the laboratory of Plant Molecular Biology and Genetic Engineering, Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya during rabi season of 2018-2019. Heat stress was induced by delayed sowing 35 days from normal date of sowing (25 November) so that delay sown wheat genotypes could experience heat stress at reproductive stage. Heat tolerant wheat genotypes screened on the basis of Membrane Stability Index (MSI), Chlorophyll Stability Index (CSI), stay green condition and Canopy Temperature Depression (CTD). High MSI, CSI and CTD were recorded in DBW-14, NW-1014 and Halna over other genotypes. These genotypes also showed less percent reduction in plant height, tiller number, spike length, number of grains per spike, test weight and grain yield per plant over control under heat stress regimes. Therefore MSI, CSI and CTD can be used as screening criteria for heat tolerant traits in wheat.
