Two-spotted spider mite) Tetranychus urticae) is one of the most important pests of common bean (Phaseolus vulgaris) in Iran. Common bean seedlings are susceptible to the mite and greenhouse is a suitable environment for two spotted spider mite reproduction. Accordingly, to evaluate the mite resistance, 19 common bean genotypes were planted in a completely randomized design arrangement with t...

In order to study the correlation of agronomic, morphologic and physiologic traits and their effects on grain yield of rice genotypes in two environments (favorable irrigation and water stress), 49 genotypes were evaluated using a completely randomized block design with 3 replications in two experimental conditions. All practices and conditions were the same for the two experiments with the exc...

In order to evaluate oil yield stability in oilseed rape genotypes and genotype´environment interaction, 22 oilseed rape genotypes were evaluated using RCBD design with 4 replications in Agricultural Research Station of Islam Abad-e-Gharb during 3 cropping seasons in normal and delayed sowing date conditions. Combined variance analysis showed that genotype, environment and genotype´environment ...

Soybean is the promising oilseed in the face of protein and oil shortage. In this study 16 advanced soybean genotypes, in terms of seed yield and yield components were evaluated using multivariate statistical methods. This experiment was carried out in the form of randomized complete block design (RCBD) in the research farm of Ardabil Agricultural and Natural Resources Research Center (Moghan...

In order to evaluate drought resistance indices, an experiment was carried out in a randomized complete block design in three replications with thirteen bread wheat genotypes and two levels of irrigation, stressed and non stressed, at Dry land Agricultural Research Institute (DARI), Maragheh, in 2009-2010. tolerant on the basis of yield performance in stressed (ys) and non-stressed (yp) environ...

Among different environmental stresses, drought is of great importance that induces a highly negative effect on crop production. In order to evaluate drought tolerance in dryland wheat genotypes, 36 genotypes were studied in a randomized complete block design with three replications under rainfed (drought stress) and supplemental irrigation conditions during 2016–2017 growing season in Research...
