Abstract :
In order to evaluate the application of zinc on some agronomic and physiologic traits of rapeseed promising lines under drought stress conditions, a factorial split plot experiment in a randomized complete block design with three replications for two years (2014-2015 and 2015-2015) in the institute farm Research on breeding and preparation of seedlings and seeds of Karaj was carried out. Irrigation factor and zinc were applied factorially in main plots and promising lines factor in sub-plots. In this study, irrigation at three levels including normal or control irrigation, cessation of irrigation from flowering stage onwards and cessation of irrigation from pod stage onwards, zinc in two levels including normal water (no zinc application) and foliar application with zinc 30 g / l zinc and rapeseed promising lines including Danob, HW113, KR2, L155, HL2012 were placed in subplots. The results of analysis of variance showed that the effect of irrigation, zinc and line on most of the studied traits was significant. Comparison of the mean effects of irrigation, zinc and line on most traits showed that the highest amount of normal irrigation treatment, application of zinc and L155 line was obtained. The results of comparing the means of the triple effect on most of the traits showed that the highest value was related to the L155 line in the treatment of zinc application and normal irrigation. According to the obtained results, the most suitable genotype for the region is L155.
