The genetic variation within and between wild apple samples (Malus sylvestris) and cultivated apple trees was investigated with amplified fragment length polymorphisms (AFLP) and microsatellite markers to develop a conservation genetics programme for the endangered wild apple in Belgium. In total, 76 putative wild apples (originating from Belgium and Germany), six presumed hybrids and 39 cultiv...
In order to evaluate the genetic variability of Iranian wheat landraces and cultivars and to determine the relationship between grain yield and other traits, 313 Iranian wheat genotypes including 203 Iranian wheat landraces and 110 Iranian cultivars were planted in a three separated augmented design along with three check cultivars repeated in seven blocks in 2014 on the research field of ...
introduction despite the fact that iran is one of the major chickpea (cicer arietinum l.) center of origins, limited information is available regarding chickpea genetic variation and diversity. genetic diversity information is crucial for the choice of proper parents to establish new breeding programs. chickpea germplasm is poor, suggesting the need for gaining enough knowledge of genetic diver...
The genetic diversity of a large number of pistachio genotypes grown in Iran is not exactly known. Most of the studies on genetic diversity of Iranian pistachio varieties are based on morphological characteristics or isozyme markers. In the present study, the genetic diversity of selected pistachio cultivars along with some wild species were evaluated by Amplified Fragment Length Polymorphism (...
A cytogenetical study on 13 alfalfa (Medicago sativa) cultivars available in Iranian Forest and Rangelands Genebank was performed in order to obtain basic information on the variability in chiasma frequency/distribution, chromosome association and segregation. Such cytogenetic information is useful for planning hybridization programs. Cluster analysis of meiotic data and ordination of cultivars...
olive cultivars with specific characteristics have been developed thanks to iran’s particular climatic conditionsand long-term olive cultivation. the genetic variation and relationships among 40 olive cultivars, as well as 17 unknown genotypes from the national olive collection orchard at tarom research station, zanjan, iran, were evaluated using ssr markers. using 10 microsatellite primer pair...
Due to the importance of date palm production in Iran, introduction of new cultivars, improvement of current cultivars and studying the genetic diversity among available cultivars is essential for improvement the quantity and quality of date palm production. In this research, 15 different local genotypes of date palm collected from Saravan, Jalgh, Nahook and Sinokan regions of Sistan and Baluch...
burnout is a response to the chronic work stress which is prevalent mostly among the people who do people job, like teaching. the purpose of this study was to develop a valid and reliable instrument that can measure burnout in foreign language teachers. although some widely used instruments were developed before which measured burnout in teachers, a specific instrument which include specific sy...
Various strategies have been developed to reduce water consumption in rice cultivation, including rice cultivation in water-saturated soil, drying and wetting of the soil (periodic irrigation), and aerobic rice cultivation. In this study, in order to identify and grouping rice cultivars suitable for aerobic cultivation, 34 cultivars of native and improved rice cultivars were selected and eval...
micropropagated plantlets derived from three different grape rootstock genotypes namely, dogridge (vitis champini), so4 (v. berlandieri×v. rupestris) and ari-h-144 (v. vinifera×v. labrusca) were subjected to randomly amplified polymorphic dna (rapd) and inter simple sequence repeats (issr) analyses in order to evaluate their genetic stability and/or detect likely existing variations among in vi...
