The genetic improvement of banana and plantain has focused on breeding for resistance to black sigatoka. This has been quite successful, but the distribution of improved hybrids has been impeded by the outbreak of Banana streak virus (BSV). Integration of viral sequences in Musa genomes make it diffi cult to apply commonly accepted principles for host-plant resistance. The short-term strategy o...
abstract the primary purpose of this study was to explore the actual practices and cognitions of two groups of iranian eap teachers, i.e. language teachers and content teachers, with respect to teaching reading-comprehension and vocabulary. to this end, tehran university of medical sciences which authorizes both groups of teachers to teach eap courses was selected as the context of the study s...
Doster, M. A., Cotty, P. J., and Michailides, T. J. 2014. Evaluation of the atoxigenic Aspergillus flavus strain AF36 in pistachio orchards. Plant Dis. 98:948-956. The atoxigenic strain Aspergillus flavus AF36, which has been extensively used as a biocontrol agent in commercial corn and cotton fields to reduce aflatoxin contamination, was applied in research pistachio orchards from 2002 to 2005...
As a perennial xerophytic shrub, characterized by plesiomorphic features, the caper (Capparis spinosa L.) is naturally spread throughout Mediterranean basin and occupies an important ecological role, as well economic one, in traditional specialized systems for commercial production. This species, spite of its wide diffusion, currently considered at risk genetic erosion, mainly due to overgrazin...
Eucalyptus nitens is the second most widely planted eucalypt species in Australia. The species is principally grown for the production of pulpwood but substantial areas are also managed for solid-wood production. The first large-scale E. nitens progeny trials were established in the 1970s and up to two cycles of breeding have since been completed. Estimates of genetic gains achieved through bre...
from its emergence till present time marxist principles has undergone great changes since their promulgation by marx. many theorists and thinkers set at rectifying marxist tenets and introducing those of their own while others advocated its main concepts and attempted at improving them. among marxist philosophers who had an intensive study of marxs ideology, is louis althusser whose reflections...
peace and national security protection and ironic solving of international conflicts become the preliminary foundation of the united nations charter and had been considered as the main responsibilities of the security council, after world war ii and the establishment of united nations organization. therefore, the security council enables to analyze every kind of conflicts and challenges which ...
Building on a solid foundation of performance testing, quantitative genetics, and statistical estimation of breeding values; recent developments in pig line improvement programs have included the application of both major gene and marker genomics, and an increased focus on genotype by environment interactions and crossbred selection objectives. Additionally, selection objectives have broadened ...
regarding islamic conferece organization's aim to establish a common market among islamic countries and expedite the establishment of regional commercial ties, various islamiic countries have been divided into five groups according to their regions. in the meanwhile this research seeks to investigate the establishment of regional commercial ties between iran and central asian countries due...
The Brazilian cattle population is mainly composed of breeds of zebuine origin and their American derivatives. Comprehensive knowledge about the genetic diversity of these populations is fundamental for animal breeding programs and the conservation of genetic resources. This study aimed to assess the phylogenetic relationships, levels of genetic diversity, and patterns of taurine/zebuine admixt...
