To evaluate genetic variation and to study of dry matter remobilization towards seed, 64 bread wheat genotypes were examined in two separated experiments using Alpha-Latic design of 2 replications during 2002–2003. Significant differences observed for most traits in normal and drought conditions. There were considerable variations among genotypes for independent parameters of dry matter remobilization to different plant parts in the two environments. Seven factors explained 77. 5% and 78. 6% of total variance in normal and drought conditions, respectively. Assessment of drought resistance indices indicated that the four indices of: MP (Mean Productivity), GMP (Geometric Mean Productivity), HARM (Harmonic Index), STI (Stress Tolerance Index) were more effective than the others for a selection of drought tolerant genotypes.
