To determine gene action and heritability of grain yield related traits in rice, six rice varieties including Hashemi, Vandana, Kadous, Hassani, Shahpasand and IR36 were crossed in a diallel design in 2010. The parents and seeds of F1 generation (36 genotypes) were grown in a completely randomized block design with three replications at the Research Field of the Rice Research Institute of Iran-...

Rice is one of the most important food crops, thus identification of definitive traits on the yield can be used in breeding programs. In order to determine the best suitable morphological markers for selection of superior genotypes, seeds of 15 rice genotypes including 5 varieties (namely: Binam, Dasht, Neda, Mashhad Domsiah and IR62871-175-1-10) and their 10 F1 hybrids of corresponding variate...

Facilitate the selection procedure to improve performance of new genotypes of rice is essential. In present study in order to evaluate relationship between grain yields with other agronomic traits, a global rice collection including 100 accessions was seeded in an incomplete block design (triple lattice 10×10). Afterward, grain yield and 14 morphological traits were evaluated. Correlation coeff...

esl/efl books play a crucial role in shaping language learners worldview of gender roles in society. the present study investigated the status of sexism in two sets of efl textbooks, one developed by non-native iranian authors (ili series) and the other by native authors (top notch series). first, two books from each series was selected randomly. then, a quantitative analysis was carried out wi...

One of the factors which affect the quality of rice during milling is internal fissures created during and after drying operation. In many industrial countries intermittent drying method is hired to reduce the moisture content of rough rice in order to reduce the drying time and maintain the quality of the final product. A high percentage of rice breakage during milling process, at least in Ira...

Plant growth regulators (PGRs) are used to prevent reduction in rapeseed grain yield under limited moisture conditions. A field experiment was conducted to investigate the effect of paclobutrazol (0, 50, 100, 150 and 200 mg L-1) on canopy surface temperature and some quantitative and qualitative characteristics of two rapeseed cultivars (Okapi and Natalie) under full irrigation and late season ...

the subjects of the study are only the tefl teachers and students at gilan university. to obtain the desired data, a questionnaire which was based on the theories and disecussions gathered, was used as the main data gathering instrument. to determine the degree of relationship between variables, covariance and pearson product moment correlation coefficient were the formulas applied. the data we...

in the past couple of decades sociocultural theory of sla and its implications in efl contexts have attracted attentions of research circles worldwide and aroused some controversies. firth and wagner (1997) have questioned the principles of the cognitive view which gives importance to mental constructs in favor of sociocultural view which highlights social and contextual constructs. but if soci...
