One component of integrated weed management is use of cultivars with high competitive ability against weeds. Balance between competitiveness and productivity of rice under condition of presence or absence of weeds, is complicated the breeding of rice cultivars to increase competitiveness against weeds. Path coefficient analysis has been widely used in crop breeding to determine the nature of re...

this thesis attempts to investigate the effects of prelistening activities on enhancing iranian efl learners` listening comprehension. the present study investigated ways in which learners` background knowledge could be activated in order to enhance their l2 listening comprehension by limiting the number of possible text interpretations prior to listening. the experiments conducted in this study examined the effect of prior knowledge and vocabulary teaching on iranian efl learners listening comprehension. the current study has two purposes: one is to investigate the effect of background knowledge on the second language listening comprehension of iranian intermediates and the other is to determine whether second language is facilitated by the introduction of unknown vocabularies in the form of prelistening activities. to conduct the study different instruments such as listening proficiency test and four listening tests such as pre and posttests were used and various statistical processes and techniques including paired-sample t-test, and analysis of variance (anova) were used. the findings of this study supported all three hypotheses tested. differences were found between the means of preteaching vocabulary variable, the background knowledge activation variable, and mean difference between these two strategies variable. subjects scored higher when the unknown words were taught in advance. likewise, subjects scored higher when they were asked some relevant questions about the topic than on those without them. there was, in addition, a significant difference between the means of preteaching vocabulary strategy and background knowledge activation strategy. in fact, preteaching vocabulary had a better effect in enhancing the students’ listening comprehension, in comparison to background knowledge activation strategy.

in order to study genetic diversity in 178 accessions of lentil (lens culinaris medik) originated from warm climate regions of iran, this experiment was conducted in 2009 at research farm of the national plant gene bank of iran in karaj. experimental design was an augmented experiment with six blocks and each block containes 30 accessions. accessions were compared with promising lines including...

Determining the relationships between morphological traits is very important in plant breeding. For this purpose, path analysis and biplot analysis are among the most effective statistical methods. To study the morphological traits affecting faba bean seed yield, 12 introduced faba bean genotypes were studied under the influence of 3 concentrations of gibberellic acid based on split plot in a r...

Mutagenesis has been one of the important sources of genetic diversity and Plant mutants can be important bio-resources for crop breeding and functional genomics studies. Breeding conventional methods for generating of genetic variability are of low efficiency. We showed that treatment of seeds of rice(Hashemi cultivar) with 0.8% EMS for 8 h caused visible phenotypic variations on M2 rice mutan...

Wide variation for morphological traits exists in Brassica rapa and the genetic basis of this morphological variation is largely unknown. Here is a report on quantitative trait loci (QTL) analysis of flowering time, seed and pod traits, growth-related traits, leaf morphology, and turnip formation in B. rapa using multiple populations. The populations resulted from crosses between the following ...

This study was conducted to investigate the genetic diversity of alfalfa genotypes by multivariate analyses using agronomic and morphological traits. For this purpose, 20 alfalfa genotypes with local control Baghdadi was considered as the first factor and three harvest was used as the second factor. This experiment was performed to split plot at the time in randomized complete block design with...

Yard long bean (Vigna unguiculata var. sesquipedalis L.) is one of the important leguminous vegetables in Bangladesh. However, yield this vegetable much lower Bangladesh compared to other yard beangrowing countries. Therefore, it crucial improve vegetable. In present study, genetic variability, heritability, character association and diversity were evaluated on randomized complete block design ...
