Appropriate selection of donor parent for breeding purposes needs sufficient knowledge about genetic diversity and germplasm classification. In order to investigation and classification of genetic diversity in 35 wheat (Triticum aestivum L.) genotypes, an experiment was conducted in University of Shahed based on randomized complete block design with 2 replications in 2009. In persent study 15 m...
The response of bread wheat genotypes to weed interference was evaluated under dryland conditions. An experiment was conducted with 26 genotypes of bread wheat and two known cultivars, Sardari and Azar2, as checks in a strip plot (Split block) arrangement based on Randomized Complete Block Design (RCBD) with four replications in 2002-03 at Dryland Agricultural Research Institute, Srarood, Ker...
in order to study of drought tolerance in bread wheat genotypes, this study was conducted in maragheh dryland agricultural research station. the study included two experiments and the statistical design of each experiment was a rcbd with four replications, and 20 bread wheat genotypes that were compared under drought stress (rainfed) and supplementary irrigation. analysis of simple variance sup...
a note on character kernels in finite groups of prime power orde
In order to evaluate the productivity potential of some bread wheat varieties and promising lines under no-till rainfed condition two different on-farm trials were conducted in cold (Sonqor) and warm (Sarpol-e Zahab) regions of Kermanshah province during 2017-18 cropping season. In the cold condition, 12 winter genotypes and in the warm condition 32 spring genotypes were evaluated for grain ...
The effect of flooding can be a serious problem for wheat farmers, even at dry land condition. Amount of flooding damage depends on duration flooding, developmental stage, wheat type and variety. Therefore as a factorial experiment in randomized complete design based on winter bread wheat cultivars (Pishtaz, Marvdasht, Shiraz, Zarin, Shahriar, C-81-4, Sardari, Agosta seed, FGS and Azar2) at sta...
the time of duration of plant developmental stages could have an effect on crop yield and adaptation in a specific environment. the aim of this study was to evaluate the phenological behavior in a wide range of wheat cultivars and their relation with adaptation and potential of crop production in a specific climate (semi-arid and cold). by using a simple lattice design with three replications i...
management of chemical fertilizers application is very important issues on environment and plant yield especially in arid and-semi arid region. in order to determine the effects of drought stresses and fertilizer levels on quantity and quality yields of psyllium (plantago ovata l.), a study was conducted as split plot based on randomized complete block design with four replications at the natur...
Grain development in cereals depends on synthesis and remobilisation compounds such as water-soluble carbohydrates (WSCs), amino acids (AAs), minerals environmental conditions during pre- post-anthesis. This study analyses the impact of water stress metabolite (WSCs, AAs nitrogen) dynamics between source (leaves stems) sink (grain) organs triticale, bread wheat, durum wheat barley. Plants were ...
Stay-green, a key trait of wheat, can not only increase the yield of wheat but also its resistance to heat stress during active photosynthesis. Cytokinins are the most potent general coordinator between the stay-green trait and senescence. The objectives of the present study were to identify and assess the effects of cytokinins on the photosynthetic organ and heat resistance in wheat. Two winte...
