in order to locate qtls controlling some agronomic traits associated to drought stress and to determine their relationships with grain yield, an experiment was conducted at the research farm, college of agriculture, university of zabol in 2011. the experiment was arranged in two complete block designs with 3 replications. 72 barley double haploid lines including their parents (steptoe×morex) we...
one of the most important number sequences in mathematics is fibonacci sequence. fibonacci sequence except for mathematics is applied to other branches of science such as physics and arts. in fact, between anesthetics and this sequence there exists a wonderful relation. fibonacci sequence has an importance characteristic which is the golden number. in this thesis, the golden number is observed ...
Many agriculturally important traits are complex, affected by many genes and the environment. Quantitative trait loci (QTL) mapping is a key tool for studying the genetic structure of complex traits in plants. In the present study QTLs associated with yield and agronomical traits such as leaf number, leaf length, leaf width, plant height, stem and head diameter were identified by using 70 recom...
Composite interval mapping (CIM) is the most widely-used method in linkage analysis. Its main feature is the ability to control genomic background effects via inclusion of co-factors in its genetic model. However, the result often depends on how the co-factors are selected, especially for small-effect and linked quantitative trait loci (QTL). To address this issue, here we proposed a new method...
the history of plant’s used for mankind is as old as the start of humankind. initially, people used plants for their nutritional proposes but after the discovery of medicinal properties, this natural ?ora became a useful source of disease cure and health improvement across various human communities. berberis vulgaris is one of the medicinal plants used in iranian traditional medicine. berberis ...
27 28 Most standard quantitative trait locus (QTL) mapping procedures apply to populations derived 29 from the cross of two parents. QTL detected from such bi-parental populations are rarely 30 relevant to breeding programs due to the narrow genetic basis; only two alleles are involved per 31 locus. To improve the generality and applicability of mapping results, QTL should be detected 32 using ...
all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
تاثیر آموزش تفکر انتقادی به شیوه مباحثه بر روی مهارت درک متن یادگیرندگان انگلیسی به عنوان زبان خارجی
the purpose of the present study was to investigate the effect of instruction through debate on male and female efl learners’ reading comprehension, to examine the differences between the performance of male and female participants on the five dimensions of cctst including analysis, evaluation, inference, deductive reasoning, and inductive reasoning, and to examine the differences between male ...
Most standard QTL mapping procedures apply to populations derived from the cross of two parents. QTL detected from such biparental populations are rarely relevant to breeding programs because of the narrow genetic basis: only two alleles are involved per locus. To improve the generality and applicability of mapping results, QTL should be detected using populations initiated from multiple parent...
This article proposes a quick method for computing approximate threshold levels that control the genome-wise type I error rate of tests for quantitative trait locus (QTL) detection in interval mapping (IM) and composite interval mapping (CIM). The procedure is completely general, allowing any population structure to be handled, e.g., BC(1), advanced backcross, F(2), and advanced intercross line...
