Identification of Heat Stress Traits in Wheat (triticum Aestivum L.) in the Way of Tagging Major Gene(s) for Heat Stress Tolerant
A field experiment was conducted with four wheat varieties Raj4134, HD2733, NW 1014 and K9006 for characterization of heat stress tolerance traits under heat stress condition. Heat stress was induced by delayed sowing of 35 days from normal date of sowing so that grain filling stage of wheat could experience severe heat stress. Data related to plant height, chlorophyll content, starch content a...
متن کاملThe impact of terminal heat stress on yield and heat tolerance of bread wheat
In arid and semi-arid regions of the world bread wheat (Triticum aestivum L.) yield is highlylimited due to late season heat stress, mostly occurring during the reproductive phase. Hence thecurrent study was conducted to evaluate the effect of late season heat stress on grain yield andyield components of 20 spring bread wheat cultivars. For this purpose, a stripe block experimentincluding four ...
متن کاملGrain Filling Rate and Duration in Bread Wheat Under Irrigated and Drought Stressed Conditions
Abstract Eleven wheat cultivars were evaluated at 10-day intervals, beginning from anthesis, under irrigated and drought stress conditions during 2006-2007. The effects of irrigation, genotype and date of harvest were significant for most of the studied characters. Water deficit decreased pre-and post-anthesis assimilation rate, grain weight per spike, grain number per spike and 1000 grain wei...
متن کاملHeat tolerance around flowering in wheat identified as a key trait for increased yield potential in Europe under climate change
To deliver food security for the 9 billon population in 2050, a 70% increase in world food supply will be required. Projected climatic and environmental changes emphasize the need for breeding strategies that delivers both a substantial increase in yield potential and resilience to extreme weather events such as heat waves, late frost, and drought. Heat stress around sensitive stages of wheat d...
متن کاملEvaluation of Wheat Chromosome Translocation Lines for High Temperature Stress Tolerance at Grain Filling Stage
High temperature (HT, heat) stress is detrimental to wheat (Triticum aestivum L.) production. Wild relatives of bread wheat may offer sources of HT stress tolerance genes because they grow in stressed habitats. Wheat chromosome translocation lines, produced by introgressing small segments of chromosome from wild relatives to bread wheat, were evaluated for tolerance to HT stress during the grai...
