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...

Identification of environment-specific QTL and stable QTL having consistent genetic effects across a wide range of environments is of great importance in plant breeding. Inclusive Composite Interval Mapping (ICIM) has been proposed for additive, dominant and epistatic QTL mapping in biparental populations for single environment. In this study, ICIM was extended to QTL by environment interaction...

Epistasis is a commonly observed genetic phenomenon and an important source of variation of complex traits, which could maintain additive variance and therefore assure the long-term genetic gain in breeding. Inclusive composite interval mapping (ICIM) is able to identify epistatic quantitative trait loci (QTLs) no matter whether the two interacting QTLs have any additive effects. In this articl...

Experimental allergic encephalomyelitis (EAE), the principal animal model of multiple sclerosis, is genetically controlled. To date, 13 disease-modifying loci have been identified in the mouse by whole genome scanning using an F2 intercross between EAE-susceptible SJL/J and EAE-resistant B10.S/DvTe mice. Two quantitative trait loci (QTL), eae6 and eae7, on chromosome 11 were identified by class...

Let I⊂(0,∞) be an interval that is closed with respect to the multiplication. The operations Cf,g:I2→I of formCf,g(x,y)=(f∘g)−1(f(x)⋅g(y)),where f,g are bijections I considered. Their connections generalized weighted quasi-geometric means presented. It shown invariance question within class these leads iterative type and a problem on composite functional equation.

Little is known about the genetics controlling the rate of embryonic development in salmonids, despite the fact that this trait plays an important role in the life history of wild and cultured stocks. We investigated the genetics of embryonic development rate by performing an analysis of quantitative trait loci (QTL) on two families of androgenetically derived doubled haploid rainbow trout prod...
