Half diallel crosses of nine Iranian wheat cultivars were used to estimate the general and specific combining ability effects and other genetic parameters related to yield and its components. Parents with F2 generations were evaluated at Research Farm, College of Agriculture, University of Shahrekord, in a randomized complete block design with 3 replications. Partitioning of genotypes mean squa...
in order to determine the best traits related to indirect increasing of grain yield, five wheat genotypes (zagros, tajan, durum cul., kohdasht and n-81-18 line) were evaluated by using randomized complete block design (rcbd) with 4 replications in research field of gorgan university of agricultural sciences and natural recourses. the studied traits included leaf area index (lai), crop growth ra...
In order to evaluate the relationship between morphological characters in rice lines two populations at F3 generation were grown in research field of Agricultural Sciences and Natural Resource University, Sari, Iran, during 2012. Statistical analysis on important agronomic traits showed that maximum standard deviation belonged to total grain number followed by filled grains per panicle and grai...
during grain development, appropriate water status of soil has key importance for starch accumulation in grains and hormone changes. for this, the study carried out on two iranian wheat cultivars pishtaz and karaj 3 in a factorial experiment based on randomized complete block design with three replications under irrigated and drought in a field experiment at research farm of agriculture college...
The speed with which neurones in the monkey temporal lobe can respond selectively to the presence of a face implies that processing may be possible using only one spike per neurone, a finding that is problematic for conventional rate coding models that need at least two spikes to estimate interspike interval. One way of avoiding this problem uses the fact that integrate-and-fire neurones will t...
objective: wheat is the most important crop in iran. self sufficiency in wheat production is one of the economic and food safety policies in the country. in spite of the efforts which have been made in this area, the mean of wheat yield in iran is less than its world average. methods: in order to identifying of the high yielding wheat lines with optimal characteristics and to determine the trai...
Summary The purpose of this research is to examine the variability in yields and yield components wheat cultivars Northern Serbia, visualize their groupings relationships, determine correlations between traits using principal analysis (PCA). A total fifteen genotypes (Triticum aestivum L.), developed 10 different countries over a period exceeding 70 years, were analyzed during growing seasons 2...
Inflorescences of the tribe Triticeae, which includes wheat (Triticum sp. L.) and barley (Hordeum vulgare L.) are characterized by sessile spikelets directly borne on the main axis, thus forming a branchless spike. 'Compositum-Barley' and tetraploid 'Miracle-Wheat' (T. turgidum convar. compositum (L.f.) Filat.) display noncanonical spike-branching in which spikelets are replaced by lateral bran...
application of various composts has been intensified in agriculture, due to manifestation of negative effects of chemical fertilizers on environment and soil fertility. however, their usage should be accompanied by environmental and nutritional studies. to study the effects of sulfur granular compost on yield and yield components of two wheat cultivars, a pot experiment was conducted in a compl...
Abstract Eleven wheat cultivars were evaluated at 10-day intervals, beginning from anthesis, under irrigated and drought stress conditions during 2006-2007. The effects of irrigation, genotype and date of harvest were significant for most of the studied characters. Water deficit decreased pre-and post-anthesis assimilation rate, grain weight per spike, grain number per spike and 1000 grain wei...
