| Abstract: |
| To understand the effects of drought stress on yield and quality of spring wheat in Ningxia, 20 spring wheat varieties(lines) with good quality and drought tolerance were selected, a two\|factor split plot experiment was conducted to compare the differences in yield and quality of wheat under different irrigation treatments. The results showed that the grain number per ear, number of effective panicles and yield of wheat decreased significantly by 10.19%, 11.01% and 39.13% respectively under drought stress, but the number of grains per ear of Ningchun 39, Ningchun 50, Ning 2038 and the number of effective panicles of Ningchun 54, Yong 08-1 did not decrease, and the change of 1000\|grain weight, fertile spikelet and average spike length was not significant. The bulk density, protein content and sedimentation value were increased by 0.76%, 14.17% and 11.44% respectively under drought stress, however, the hardness, wet gluten content, water absorption andmaximum tensile resistance were significantly affected by different genotype. In addition, the maximum tensile resistance had the largest variation range from -17.72% to 46.55%. Most of the varieties increased significantly,including Ningchun 4, Ningchun 39, Ningchun 41, Ningchun51, Ningchun54, Ningchun56, Ningchun57, Ningchun 58, Ningchun 60, Ningchun 61, Yongliang 15, Yong 08-1 and Yong 3463. According to the subordinate function method, Ningchun 54, Ningchun 56, Ningchun 39 and Ningchun 50 were the top drought\|resistant varieties. Ningchun 54, Ningchun 52 and Yongliang 15 had better yield and quality under drought stress, the yield of this population was 4 031 kg·hm-2, and the quality indexes reached the second level of national strong gluten level except the stable time. It is inferred that Ningchun 54 may have a better comprehensive performance in arid regions based on the results of drought resistance evaluation and cluster analysis. |
