Genetic characterization, diversity analysis and estimate of the genetic relationship among varieties using functional and random DNA markers linked to agronomic traits can provide relevant guidelines in selecting parents and designing new breeding strategies for marker-assisted wheat cultivar improvement. Here, we characterize 20 Moroccan and 19 exotic bread wheat (Triticum aestivum L.) cultiv...
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...
Wheat grain yield reduction occurs in most wheat growing regions of Iran due to post-anthesis water stress. This research was conducted to evaluate yield and yield components of wheat cultivars in normal irrigation and post anthesis irrigation cut-off conditions as a split-plot arrangement based on a randomized complete block design with three replications during 2015-16 in College of Agricultu...
in this study, we aimed to determine the effects of halo-priming on yield and yield components of four wheat cultivars in a saline soil. a field study was conducted in factorial based on randomized complete block design (rcbd). soil ph was 8/1 and electrical conductivity was 9 ds/m. wheat cultivars (falat, ghods, chamran and shoori4) were primed with cacl2 solutions (control, 0, 50 and 100 mm)....
abstract due to calcareous soil conditions, zinc deficiency is a yield limiting factor for wheat production in iran. one solution for this problem is the cultivation of zn-efficient wheat varieties. ten wheat cultivars (nine bread wheat and one durum wheat) with different tolerance to zn deficiency were studied in a greenhouse experiment. plants were treated with zn (10 mg zn kg-1 soil as znso4...
Abstract: Wheat grain yield is reduced by post-anthesis drought stress conditions in most wheat growing farmlands of Iran. To evaluate the effect of post-anthesis-withholding irrigation on yield, yield components and canopy temperature of wheat cultivars, a field experiment was conducted as split plot in a completely randomized block design with four replications at experimental farm of coll...
concinciding of wheat growth in post-anthesis period by water deficiency can result in reduction of current photosynthesis. in this circumstance stem-stored carbohydrate from pre-anthesis period had an important role in supporting assimilates for growing grain. an experiment was conducted in 2007-8 in experimental farm of arsanjan islamic azad university, in order to investigation the quantity ...
In order to evaluate grain yield potential and study dry matter remobilization to seed, 8 commercial bread wheat cultivars were examined in two separate experiments, using randomized complete block design with 4 replications in 2003. There were significant differences for most traits in normal and drought conditions. Sarday variety had the least grain yield in the two environments. There was c...
Salinity is one of a major abiotic stress, specifically on arid and semi-arid areas that has influenced on crop growth and reduced grain yield. The purpose of present study was identification of agronomic traits related to wheat grain yield variation under control and salinity conditions. In order to produce a population of 272 recombinant inbred lines (RILs), a cross between two bread wheat cu...
