the objective of this experiment was to investigate inheritance and gene action for resistance to sunn pest (eurygaster integriceps) and related traits in bread wheat including f1, f2 and backcross generations derived from a cross between line 15 as resistance and line 12 as susceptible parents. parents along with f1, f2, bc1 and bc2 generations were evaluated in a randomized complete block des...

fennel (foeniculum vulgare mill.) benefits from a lot of useful medicinal properties. iran is known as one of the main producers of fennel. in spite of high medicinal values, fennel’s cultivation is not economically feasible, mainly due to its low yield. it grows wild in different areas in iran from where diverse ecotypes have evolved. genetic variance and heritability estimates of traits in a ...

teachers beliefs have usually been left unattended in the realm of educational research in iranian context. one of those beliefs which seems to impact teachers performance in the classroom is their sense of self-efficacy, which refers to teachers belief in their ability to enhance student achievement and in bringing about positive learning outcomes. the present study aimed to investigate the pr...

Estimation of the components of variance for a quantitative trait allows one to evaluate both the degree to which genetics influences the trait and the trait's underlying genetic architecture. For particular traits, the estimates also may have implications for discriminating between potential models of selection and for choosing an appropriate model for linkage analysis. Using a recently develo...

Knowledge of genes action on important traits and their breeding value is necessary to achieve high yielding cultivars in food crops. Molecular markers has eliminated the need for knowing the pedigree of genotypes for estimating Kiniship matrix required to estimate breeding values of taits of interest. In this research, 97 genotypes of maize were evaluated for 17 different agronomic triats usin...

in order to estimate heritability and gene action for grain yield and its related traits in lentil, six basic generations were evaluated in a randomized complete block design with three replications in a field experiment. besides seed yield per plant, plant height, pod length, and 100-seed weight, the number of pods per plant, primary branches, clusters per plant, nodes per main stem, secondary...

This study was done to investigate and compare fruit yield, yield components, morphological traits and fruit quality of greenhouse tomato genotypes in order to use them as selection criteria. Progenies of 49 crosses of greenhouse tomato together with their 13 parents were evaluated using Randomized Complete Block Design with three replications. The highest amount of fruit yield was observed in ...

The study of the genetic structure controlling agronomic traits is one of the preconditions for selecting the appropriate breeding method. In order to analyze genetic of some agronomic traits of bread wheat using generation mean analysis, parents and different generations resulting from the cross of Marvdasht × MV-17 wheat cultivars were assessed in a randomized complete block design with three...
