the present study investigated the calpain gene diversity in iranian one-hump camels (120 camels) using pcr-rflp method. three genotypes aa, ag and gg were observed with the frequencies of 0.02, 0.19 and 0.78, respectively. the frequencies of a and g alleles were 0.12 and 0.88, respectively. the chi-squared test didn’t show significant deviations from hardy-weinberg equilibrium (p<0.05). associ...
the purpose of this study was to investigate iranian efl learners’ beliefs about the role of rote learning (rl) in vocabulary learning strategies; besides, the study examined if english proficiency would influence learners’ vocabulary learning strategy use. this study addresses the need for a clear understanding of the role of rl in efl vocabulary learning by looking at iranian efl learners’ ow...
the present study aimed at investigating the relationship between iranian efl teachers’ classroom management orientations and their teaching styles. additionally, the difference between male and female teachers’ teaching styles and classroom management orientations and their relationship with experience and age were explored. three hundred efl teachers filled in attitudes and beliefs on classro...
In order to evaluate intra-genomic variation and regression analysis of grain yield and its components using two wheat substitution lines series including substitution lines of ‘Timstein’ and ‘Red Egyptian’ into genetic background of ‘Chinese Spring’ and their parents in a randomized complete block design with four replications under water-stress and non-stress conditions in a greenhouse at 201...

Materials and Methods. In this study, 89 single crosses hybrids including 60 single crosses derived from hybridization of 20 S6 inbred lines as female parents and 3 S6 commercial elit tes...
many agriculturally important traits are complex, affected by many genes and the environment. quantitative trait loci (qtl) mapping is a key tool for studying the genetic structure of complex traits in plants. in the present study qtls associated with yield and agronomical traits such as leaf number, leaf length, leaf width, plant height, stem and head diameter were identified by using 70 recom...
