Abstract

To study the response of BREAD WHEAT genotypes to DROUGHT STRESS in post-anthesis stage of drought resistant genotypes, this experiment was conducted with 18 kinds of BREAD WHEAT genotypes. The experiment was performed in a RBCD with 3 replications under normal and DROUGHT STRESS conditions during 2004- 2005 and 2005- 2006 cropping seasons in Karadj Agricultural Research Station. Combined analysis of grain yield showed that effect of time of the year, irrigation, genotype and interaction effect of genotype × year were significant. Only the effect of irrigation and genotype were significant in harvest index. Using SSI and TOL genotype C-83-7 and using STI, MP and GMP genotype C-83-8 were determined as the most tolerant genotypes. Correlation coefficients of these indices with each other for indices such as MP, GMP and STI were significant. Because STI was correlated with MP, GMP, TOL and SSI indices and also differentiated the genotypes belonging to "A" group from other group effectively, therefore, it could be recommended as the most suitable index for the selection of DROUGHT TOLERANCE BREAD WHEAT genotypes.
