Abstract:

Combine effects of drought and high temperature, causes significant reduction in wheat (Triticum aestivum L.) quality and yield worldwide. The objective of this study was to quantify independent and combined effects of drought and high temperature stress in eight bread wheat genotypes at anthesis and 21 days after anthesis (DAA). To determine the effect of combine stress present experiment were conducted in randomized complete block design with five replications. In order to assess the relative capability of stress tolerance water relation parameters (relative water content, water potential and osmotic potential) and grain yield per plot were studied. Results of genotype × environmental interaction showed grain yield reduction was significant under drought stress. Wheat genotypes showed significant reduction under terminal heat and drought stress condition, except DHTW-60 and C-306. The multiple statistical procedures used in this study showed that osmotic potential, water potential and grain yield is the most important trait for tolerant genotype selection. It is suggested that more emphasis should be given on the physiological characters for selecting wheat genotypes with higher grain yield under both (drought and high temperature) condition.
