Abstract
An experiment was carried out to study the grain yields and quality criteria of contrasting wheat (Triticum aestivum L.) cultivars, DK961 (salt-tolerant) and JN17 (salt-sensitive) in response to a series of salinity levels (0, 50, 100, 150 mM). Salinity led to a reduction in grain yields of both cvs, however, DK961 was less affected than JN17. For grain quality, the 1000-seed weight of JN17 was rapidly reduced in saline conditions compared to the control, while it declined slightly in DK961. Grain protein content of DK961 increased by 0.2, 0.7 and 3.5%, respectively in 50, 100, 150 mM NaCl treatments compared to control. Those figures of JN17 reached 1.5, 5.3 and 9.9%. Flour yield of DK961 declined by 2.6, 3.7 and 3.9%, respectively in the above-mentioned salt treatments than control. The extent of reduction in flour yield was larger in JN17 than in DK961. Salinity induced positive effects on ash content and sedimentation volumes. The pasta quality parameters, e.g. wet gluten content, water absorbance, dough development time and dough stability time of DK961 displayed nonsignificant (P >0.05) changes under 50 and 100 mM NaCl concentrations against the control, while they declined considerably in the 150 mM NaCl treatment. However, pasta quality of JN17 declined significantly along with a reduction in grain yield under all levels of salt concentration. Our results suggested that wheat grain quality was closely associated with its growth under salinity stresses. Therefore, to obtain high grain yield and better quality of wheat in saline farmlands, only salt-tolerant wheat cultivars should be considered. _____________________________________________________________________________________________________________
