English Abstract
A field study was carried out at two different isohyets locations of Iraqi Kurdistan Region (stress; Duhok and normal; Hawler) to investigate eight bread (Abu-Ghraib-3, Adana-99, Al-Iraq, Aras, Al-Rashid, Bohouth-4, Cham-6, and IBA A-99) and tow durum (Doma and Simeto) wheat for leaf proline content during the growing season 2013/14.
Also, an experiment was carried out at the laboratories of University of Natural resource and Life Sciences (BOKU), Vienna, Crop Breeding Department, to study the performance of these varieties under stress conditions for shoot and root growth measurements.
Seeds were sown in normal water (PEG 0%= 0 bar) and stress (PEG 10% = -1.48 and PEG 20%= -5.11 bars) induced by Polyethylene Glycol (PEG8000) with six replications.
The results indicated that the proline content significantly was higher under stress (0.969) as compared to (0.919) mg.g-1fw under non stress conditions.
Also, most of wheat varieties were superior in leaf proline content under stress conditions and both bread and durum varieties resembled similar responses.
PEG experiment reflected the superiority of durum wheat varieties for all shoot and root traits included in the study.
Also, all studied traits with the exception of root diameter were reduced as the stress by PEG8000 increased form 0% to 20%.
Based on the obtained results, the proline accumulation can be utilized for wheat varieties; PEG test for wheat species screening programs as PEG test implied that durum varieties can be recommended for the areas with predicted drought stress
