An experiment was conducted with four wheat varieties i.e. Halna, HD2733, Raj3765 and K9006 to evaluate heat stress traits in wheat and consequently development of high yielding heat tolerant wheat varieties. Heat stress treatment was given by delayed sowing under field condition. Parameter related to growth and yield attributing traits were observed under control and heat stress regimes. Wheat varieties Halna and Raj3765 showed less reduction in plant height, tiller numbers, chlorophyll content (SPAD value), membrane stability index, grains/spike, test weight and grain yield under heat regimes comparatively HD2733 and K9006. Though HD2733 and K9006 showed high yield under control condition but its yield significantly reduced under heat stress at reproductive stage.
