Tolerance determination of Four wheat Cultivars to different Levels of Salinity

Abstract

A pot study was implemented at Al _ Dawar Research Station during 2005-2006 according to R-C-B-D arranged as split plots with five replicates . four wheat Cultivars (IpA99، Sham 6 ، Tamooz and Abu- Graib ) were used as main treatments and five salinity levels (3 , 6 , 9 , 12 and 15 ds/m as secondary treatment . The aim of the study was to evaluate four wheat cultivars tolerance to different levels of sallnity . Result showed that yield and its components decreased with elevating salt level , especially at 12 and 15 ds/m . moreover , there were differences exist between cultivars ( IpA 99 and Sham6 ) were the most tolerant comparing with other cultivars .
