Germination Response and Seedling Traits of Lentil Landrace Genotypes to Drought and Salinity Stress and Path Analysis of Seedling Weight under Laboratory Conditions

In order to evaluate of lentil landrace genotypes response via germination and seedling traits to drought and salinity stress, one factorial experiment with three factors (drought, salinity and genotypes) on bias Completely Randomized Design was conducted with three replications at the laboratory of agricultural faculty of Islamic Azad University of Tabriz branch. The levels of factors were including two level of drought stress (control and -8 bar by PEG6000), three level of salinity (0, 2 and 4 ds/m by water of Oromyieh lake) and 15 landraces genotypes. Variance analysis result showed genotype×drought×salinity interaction was significant for all studied traits, which shows the different responses of genotypes to drought and salinity stress for all traits. Mean comparison of traits for interaction of genotype × drought × salinity showed that germination and seedling traits value in all genotypes was significantly reduced; however, this reduction was different in different genotypes. So Kaleybar and Shavi Varzeghan genotype expressed least reduction of these traits. The regression and path analysis for seedling weight showed length of root had the highest direct on seedling weight under drought and salinity stress.
