| Abstract: | The leaf proline content of Chinese Spring (recipient)/Hope (donor) and Chinese Spring (recipient)/ T.elongatum (donor)substitutions under the conditions of drought and control treatments were measured. ANOVA indicated that the 4B, 5A and 5D chromosomes of common wheat may carry genes associated with the control of proline accumulation induced by osmotic stress, and the genes inhibiting the proline biosynthesis could be located in chromosome 6B and 6D. The results of Chinese Spring (recipient)/ T.elongatum (donor) were used to confirm the results obtained from common wheat. The genes related to proline accumulation induced by osmotic stress were in 5A and 5D. The genes inhibiting proline accumulation were located in 6B chromosome. |
