the responses of yield and yield components of 24 advanced bread wheat genotypes to pre- and post-anthesis drought stress conditions were studied at ardabil agricultural re-search station during the 1997-2000 cropping seasons. results showed that genotypes produced significantly lower spikes no./m2, seeds no./spike and grain yield under pre- than in post-anthesis drought stress conditions. howe...
Increasing the yield of wheat (Triticum aestivum) requires choosing resistant and compatible cultivars to different climatic conditions. In order to study the effects of salinity and drought stress on grain yield, Study of stress tolerance indices and identification of tolerant genotypes to salt and drought stress, 20 different Wheat (Triticum aestivum) genotypes were assessed in a Randomized ...
Rapid screening of plant germplasm in the early stages of growth and determining the genetic basis of wheat leaf wilting index at the seedling stage is necessary for wheat breeding programs. In the present research, leaf wilting index for 290 Iranian bread wheat genotypes, including; 90 cultivars and 200 landraces were studied under drought stress conditions at the seedling stage in 2021 in res...
In order to evaluate the response of 20 lines and cultivars of soybean to water deficit stress, an experiment was conducted at Agricultural Research Station of Gorgan in 2011 and 2012. For this Purpose, 2 separate experiments was conducted, each one in randomized complete block design, with 3 replications. In first experiment, all soybean genotypes were irrigated based on 50 mm evaporation from...
to study the tolerance of genotypes under terminal drought stress, 20 promising winter and facultative bread wheat genotypes were evaluated at karadj, ardebil, arak and hamedan agricultural research stations during 2001-02 cropping season. the experimental design in all the locations was randomized complete block of three replications. grain yield (yld), harvest index (hi), grain number per spi...
Growth and production of agricultural crops are greatly affected by water shortage. Thus, yield enhancement under drought conditions is a major goal of plant breeding. Four commercial tomato cultivars (Imperial, Pakmore VF, Strain-B and Tnshet Star), a drought-tolerant breeding line (L 03306) and their hybrid combinations were selected in this study to evaluate drought tolerance and to develop ...
This experiment was conducted to evaluate drought tolerance of different safflower genotypes as a split- plot experiment based on a complete block design with three replications. The main plot was irrigation at three levels on the basis of 70, 120 and 170 mm cumulative evaporation from Class A pan and ten different genotypes of the safflower were considered as subplots. Results of analysis of v...
Salinity stress is one of the major abiotic stresses in arid and semi-arid regions of the world, such as Iran. High genetic diversity for salinity tolerance has been observed in Iranian bread wheat genotypes. In order to analyze genetic diversity and determine the most effective characteristics on salinity tolerance, 110 bread wheat genotypes were evaluated in two conditions (non-stress and sal...
