Drought is one of the main dangers for optimum production of wheat. Achieving optimal results in breeding programs require to make informed choices of parents based on general and specific combining ability.In order to study the genetic characteristics, general and specific combining abilities and gene actions under drought stress conditions, a half diallel cross including 9 varieties of wheat ...

the thesis has been arranged into five chapters and mainly concerned with the baer-invariant of groups which is the generalization of the schur-multiplier with respect to the variety of groups. chapter one is devoted to collect some notation and background information which are needed in the next chapters. its also contains some important statements which will be generalized in this thesis. cha...

abstract this study aimed at investigating the impact of etymology strategy instruction on the development of vocabulary of iranian intermediate efl learners. etymology, knowledge of origin of words, roots, and affixes, has proved to be a controversial issue and a question of long debate with regard to its impact on the process of vocabulary learning. this study employed etymology strategy in ...

the present study sought to investigate the impact of using mind-mapping technique instruction on female elementary efl learners reading comprehension; it also investigated their attitudes towards using mind-mapping technique as a tool to improve their reading comprehension. this study followed a quasi-experimental design with two intact groups as experimental, and control groups. the participa...

In order to study the genetic control of root yield, sugar yield and white sugar yield in tropical beet, the biplot of diallel data was used. 36 hybrids derived from crosses among 9 sugar beet genotypes along with four control treatments were evaluated at Safiabad Agricultural Research Center, Dezful, Iran during 2008-2009 growing season. The experimental design was a triple lattice design with...
