Canola as an oil plant that is considered as an important plant among other oilseed plants due to its high seed performance as well as oil content. Genetic diversity is necessary for breeding program and increasing selection efficiency. This study was conducted to investigate the genetic diversity and heritability of yield and some morphological traits in spring rapeseed, at Dezful, Khozestan P...

In order to evaluate the effect of different levels of nitrogen on yield, yield components and some quality characteristics of two cultivars of rapeseed, a field experiment was conducted in Dezfoul, southwest of Iran during 2011-2012. The experimental design was a split plot in a randomized complete block design with four replications. Nitrogen levels (0, 80, 160 and 240 kg ha-1) were the main-...

In order to quantifying emergence pattern of rapeseed weeds, this experiment was conducted in 40 plots (40 quadrates at Agricultural Sciences and Natural Resources University of Khuzestan, and 30 fields of Bavi (30 quadrates), Ahvaz, Iran, in 2016-2017 growing seasons was monitored, counted and recorded weekly. Three different emergence pattern of nine weed species were identified, Prickly lett...

Limited geographic area and focused modification of rapeseed during of its breeding cases have been led to the limited genetic basis. So, the evaluation of genetic diversity in modern cultivars of canola to estimating and maintain of genetic resources is essential. In this study, the genetic diversity of 45 genotypes of rapeseed was investigated using 12 RAPD markers .Cluster analysis by Dice c...

     Selenium has a protective and positive effect on the quantitative and qualitative characteristics of the plants. In order to investigate the effect of selenium foliar application on leaf proline content and some quantitative and qualitative characteristics of rapeseed cultivars under end-season thermal stress, a factorial split plot experiment was conducted in a randomized complete block d...

In this paper, the effect of irrigation water salinity levels on seed germination, dry matter weight of seedlings at eight-leave stage, and the salt tolerance of 8 rapeseed cultivars was investigated. Relative yield reduction in saline and non saline conditions, salt sensitivity index and Van Genuchten-Hoffman methods were used to determine the salt tolerance of the cultivars. Results showed th...
