To study the effect of selenium and salicylic acid on agronomic characteristics of dry land wheat cultivars, an experiment was carried out as factorial based on Complete Randomized Block Design with three replicates at the research field station of Islamic Azad University- Arak, Iran in 2010-2011 cropping season. The experimental factors were including three levels of salicylic acid: without sa...

Introduction More than 1000 morphological markers have been identified in barley (Franckowiak and Lundqvist 2002). These phenotypic traits were observed as spontaneous or artificially generated mutants in a wide range of cultivars over decades of research. Traits identified with alternate alleles include plant height, spike morphology, and seed size, among others. Approximately 275 of these mar...

wheat crop, considering its high planting area and consumption at national scale, demand a regular yield increase. humic acid, as an organic acid obtained from humus and organic sources without any environmental destructive effects, improves wheat yield particularly in variable environment conditions. in order to evaluate the effects of different levels of humic acid on shoot and wheat yield, a...

The variability of neuronal responses is proportional to the mean in many brain areas, which suggests that neural responses might follow a Poisson distribution. In this issue of Neuron, Maimon and Assad document a surprising violation of Poisson firing. Specifically, they show that there are differences in the amount of periodic structure in spike trains across cortical areas, with multimodal s...

The present research was carried out at the Breeder Seed Production Unit, JNKVV, Jabalpur, Madhya Pradesh using twenty-one sets of bread wheat genotypes. These were sown and evaluated under timely condition in a randomized complete block design with three replication during post-rainy season 2021- In investigation thirteen morphological one biochemical trait analyzed. analysis variance indicate...

water use efficiency is positively correlated with grain yield, and being used for indirect selection of high wheat yield in drought prone environments. yet little is known about genetic control of water use efficiency. in this research, a half diallel mating design was generated from crosses between 8 bread wheat to study the genetic of water use efficiency. parents and f1 progenies were plant...

six cultivars of hexaploid wheat (hyrmand, shiraz, pishtaz, marvdasht, mahdavi, roshan ‎‎(susceptible check) and m-79-6) in subplots, and three seed treatments: i1 – seed without ‎treatment; i2- seeds artificially infected with bunt spores in 5/1000 ratio and i3- seeds treated ‎with carboxin thiram fs in main plots of a split plot trial within a rcbd with three ‎replications and 3 locations of ...

     Drought stress is the most important environmental stress that affects many morphological, physiological and, especially, yield traits of arable crops. In this research, a cross between the cultivar Gaspard (dehydrated susceptible parent) and DN11 line (drought resistant parent) was performed. F1, F2, F3, BC1 and BC2 generations along with parents, were planted and compared in a randomized...

Grain yield has a usually the low heritability, consequently to predict this trait it is recommended to use some morphological characters having a high heritability with high correlation with grain yield. To study of relationships between traits and to find out traits having the high influence on grain weight, 36 winter wheat cultivars were planted through a randomized complete block design wit...

Increasing grain yield is the most important goal in any breeding program. Since yield is a complex trait and involves several quantitative components with low inheritance, its direct evaluation is not usually sufficient and therefore it is suggested that its components be investigated instead. The objective of this study was grouping 60 inbred lines along with four check cultivars of wheat fro...
