The influence of genetic variation on invasion success has captivated researchers since the start of the field of invasion genetics 50 years ago. We review the history of work on this question and conclude that genetic variation-as surveyed with molecular markers-appears to shape invasion rarely. Instead, there is a significant disconnect between marker assays and ecologically relevant genetic ...
Barleys one of the important four major crops in the world after wheat, corn and rice. About 2.16 million hectare of arable land was cultivated by barely in 2011-2012. In order to investigate heritability and gene action was used barely half-diallel of 7 × 7 in some barley-related yield traits. For this purpose were used in 6 barley genotypes with Sahra variety (the native desert). Tests carrie...
Genetic diversity is essential to meet the diversified goals of plant breeding such as producing cultivars with increased yield, wider adaptation, desirable quality, pest and disease resistance. In this study genetic diversity and selection index of 24 genotypes of bread wheat were evaluated. The performance of 24 wheat genotypes showed that there were significant variations for the characters ...
The use of appropriate selection methods are important to increase yield in breeding programs. Utilization of selection indices is one of the most effective method for selection of superior genotypes to improve the complex traits such as seed yield. In order to evaluate the efficiency of different selection methods, 63 families of two F3 populations derived from inter-specific hybridization of ...
We compared DNA-based genetic diversity estimates with conventional estimates by investigating agronomically important traits in maize grown in the northwestern region of Pakistan. RAPD markers were used to characterize 10 commonly cultivated maize genotypes. The same material was tested for phenotypic variation of quantitative traits using replicated field trials. The genetic distances between...
introduction legumes are important sources of good quality protein in diet of people and they are valuable as animals feeding. the seed of chickpea plant (cicer arietinum l.) contains essential protein sources, which plays a significant role in the human diet. among legumes the resistance of chickpea to dehydration conditions causes a higher productivity. chickpea has a moderate tolerance to dr...
the present study aimed at exploring cognitions of iranian english teachers within the context of english for academic purposes (eap). to this end, the cognitions of two groups of eap teachers with respect to their pedagogical content knowledge (pck) and their sense of professional identity (pi) were probed. two language teachers and two content instructors who had at least five years of eap te...
Sorghum is the second most important food crop after teff in Ethiopia. The objective of study was to estimate genetic variations, heritability, and expected advances selected sorghum genotypes. Sixty-four genotypes were evaluated for 17 quantitative traits 8x8 simple lattice designs at Boko research site. analysis variance revealed highly significant differences among all traits. Phenotypic Coe...
In order to evaluation of gain yield and yield components in spring barely genotypes under normal and drought stress in flowering stage and identifying drought tolerant genotypes, sixteen barely genotypes were investigated in two separately Randomized Complete Block Design with three replications in West Azerbaijan Agricultural and Natural Resources Research Center, Urmia, Iran in agronomic sea...
Tef [Eragrostis tef (Zucc.) Trotter] is an important staple food crop, especially in Ethiopia where it is annually grown on 2.8 million hectares of land. It is important for food security in the region, in spite of having a low yield, mainly due to lodging. In this study, 15 representative landraces as well as three improved varieties have been selected for in-depth characterization of many par...
