Abstract


With a view to understand, the parameters in wheat which can be used as criteria for drought tolerance, the present investigation was carried out to screen the Iranian wheat landraces by using cigar roll method. The experiment was conducted in the Department of Plant Breeding and Genetics with three replications under Completely Randomized Design to evaluate the effect of water stress on germination and seedling growth on commercial checks of wheat and a set of 249 Iranian wheat landraces by cigar roll method. Water stress induced by using 14% Polyethylene glycol solution. and water was used in control. Data were recorded after 12 days on various seedling parameters like germination percentage, root length, shoot length, root fresh weight, shoot fresh weight, root dry weight, shoot dry weight and vigor index.. All the landraces showed differential response at 14% Polyethylene glycol in terms of seedling growth. Polyethylene glycol minimize the germination and seedling growth. On the basis of vigor index, 27 Iranian landraces were selected as drought tolerant lines. Iranian landraces IWA8600596, IWA8600846 and IWA8600715 were considered to be best top three landraces having more vigor index under water stress conditions. The identified landraces could be used as donor for development of water stress tolerant varieties.
