Abstract

In order to investigate the response of inbred bread wheat lines to drought stress caused by polyethylene glycol during vegetative growth stages, a factorial experiment was conducted in a completely randomized design with two replications in two normal environments and drought stress on 169 inbred lines. In this experiment, in order to create drought stress, polyethylene glycol with an osmotic potential of 8 MPa was used. In this study, morphological traits of shoot and root length, shoot and root weight, shoot and root dry weight, ratios of root length to shoot length, ratios of root wet weight to shoot wet weight, plant length, ratios of root dry weight to shoot dry weight, total wet weight of root and shoot and total dry weight of root and shoot were studied and statistically analyzed. The results of observational analysis showed that drought stress had a significant effect on the tested traits. The results of cluster analysis showed that the ninth cluster genotypes in both normal and drought conditions in terms of root and shoot length traits showed a higher rate than other clusters. Finally, root and shoot length components can be used as the best traits to select drought-tolerant line.
