The 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 کاملmapping qtls for heat tolerance in wheat
heat stress is a major environmental stress limiting wheat productivity in most cereal growing areas of the world. in order to map and characterize quantitative trait loci controlling heat tolerance, 144 recombinant inbred lines deriving from the cross of kauz and mtrwa116 were assessed in a greenhouse and growth chamber at 35°c. one hundred and sixty six ssr and 3 aflp markers were used to...
متن کاملUpdate on Improving Heat Tolerance in Wheat Physiological Traits for Improving Heat Tolerance in Wheat1[W]
Wheat (Triticum aestivum) represents about 30% of the world’s cereal area, with over 220 million ha cultivated worldwide, often under abiotic stress. Wheat growth can be impaired by heat stress (HS) at any developmental stage, and modeling scenarios predict even warmer temperatures in the future (Easterling and Apps, 2005). The worst impacts of rising temperatures will occur at low latitudes (w...
متن کاملeffect of terminal heat stress on yield and yield components of spring bread wheat in ahwaz
terminal heat stress in mediterranean climates like ahwaz is reduced wheat yield. in order to study effect of terminal heat stress on yield and yield components of 20 spring bread wheat cultivars, an experiment was conducted in ramin university of agricultural and natural resources, ahwaz in 2007-2008. the experimental design was stripe block design in randomized complete block design with thre...
متن کاملEvaluation of growth, yield, relative performance and heat susceptibility of eight wheat (Triticum aestivum L.) genotypes grown under heat stress
Eight spring wheat cultivars were evaluated under three heat stress conditions (early, late and very late) in order to identify suitable cultivars to develop heattolerant genotypes resistant to future global warming. Results from the study indicate that stress did not negatively affect flag leaf area in ‘Prodip’ and ‘Sufi’, flag leaf dry matter partitioning in ‘Prodip’, ‘BARI Gom-26’ and ‘S...
