To study the effect of salt-stressed environment on agronomic and morphologic characteristics in wheat (Tritium aestivum L.), 26 cultivars were evaluated under non-salt stressed and Salt-Stressed environments at two locations. The experimental design employed was a complete randomized-block with four replication. The experiments were all planted in 1989. Agronomic and morphologic characters studied were, shooting, heading time, days to maturity, biological yield, grain yield, straw yield, 1000-kernal weight, plant height, number of spikes per unit area, spikelet's/spike, grains/spike, grains/spikelet and harvest index.
Separate analysis of variance was done for the measured characters for saline and non-saline environments. Combined analysis was done for traits to find out the effects of salinity and salinity x genotype interaction. Correlation coefficients were calculated among the traits.
Salinity stress decreased all the agronomic traits except grains/spikelet. Cultivar Arvand-1 and pitic had the highest grain yield under salt-stress environment relative to the yield under non-salt stressed. The ratio of the yield of the cultivars under salt-stressed environment to the yield under non-salt stressed environment was considered as salinity resistance index. The salinity resistance index was positively correlated with the yield of cultivars under salinity stress (r=O.85**). Pitic and Arvand-I had the highest salinity resistance index.
