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...
pomegranate is an importantly popular fruit crop with iran the main center of its diversity throghout the world. the richest pomegranate genetic resources believed to exist in iran. the present investigation was carried out to study the genetic diversity of 15 genotypes of pomegranate in tarume zanjan making use of rapd markers. genomic dna was extracted from the plant,s leaf, and tested for th...
Drought stress is one of the major abiotic stresses that limits rice productivity in the world. In this study 83 diverse rice genotypes were evaluated under reproductive-stage drought stress and non-stress conditions in a completely randomized design with three replications. Eleven well known stress tolerance and susceptibility indices were calculated based on the grain yield under stress and n...
this study performed to evaluate genetic diversity of some wild and domesticated (unknown foreign cultivars) blackberries in sanru collection based on morphological traits. results showed high diversity for flowering, ripening time and fruit juice. wild genotypes showed significant differences in leaf, flower, thorn number, fruits and seed fresh weight compared to domesticated cultivars. based ...
Evaluation of relationships is of prime importance in any breeding studies. In current research, genetic diversity among different rapeseed genotypes from several geographical origins including Canada, Australia, Germany, France, Denmark, Netherlands, Sweden, Iran, and Somegenotypesof unknown origin, were evaluated by RAPD and ISSR markers. All of the generated bands using 12 RAPDs and 15 ISSRs...
Leaf Rust or rust fungus Pucciniatriticinacauses leaf, Is one of the most destructive fungal disease of wheat worldwide. In this study, in order to resistance evaluate to brown rust on 41cultivars of wheat was in field and greenhouse situation and based on randomized complete block design with three replication. Traits including infection type, disease severity, Area under Disease Progress Curv...
Canonical discriminant analysis (CDA) in combination with cluster analysis and genotype by trait (GT) biplot analysis methods were used to assess 9 wheat cultivars having different degrees of tolerance along with 36 F1 hybrids derived from partial diallel crosses, using stress tolerance indices, in two levels (well watered and cessation of irrigation at pollination stage). Cluster analysis clas...
PURPOSE This study utilized multiple genetic analyses to detect evidence of maternal MS acquisition in children with S-ECC. METHODS Twenty-seven mother/child pairs were selected from children with 5-ECC preceding dental rehabilitation under general anesthesia. Plaque samples were collected from the mother, child, and the child's carious lesion. Arbitrarily primed-polymerase chain reaction (AP...
abstract: country’s fiber optic network, as one of the most important communication infrastructures, is of high importance; therefore, ensuring security of the network and its data is essential. no remarkable research has been done on assessing security of the country’s fiber optic network. besides, according to an official statistics released by ertebatat zirsakht company, unwanted disconnec...
this study was conducted to investigate the effect of favorite-text on iranian intermediate efl learners’ vocabulary development. sixty learners from nour-al-mahdi english institute participated in the present study. having been homogenized by oxford placement test (opt), they were randomly assigned into two groups of 30, control and experimental. then both groups sat for a pre-test which was a...
