比较了两种高原环境下16个春小麦品种籽粒蛋白质含量、出粉率、沉淀值及粉质参数8个品质性状.结果表明:①品种间品质有明显差异;不同品种的品质对高原环境的敏感性有差异,有的品种不敏感,表现稳定.②两种高原环境间籽粒蛋白质含量无显著差异,但黄土高原的面团流变学特性明显优于青海高原的,表明青海高原不利于蛋白质质量的提高.③青海高原小麦品质育种应提高蛋白质质量,培育制作优质馒头和面条的品种,并注重弱筋小麦培育. |

Eight quality characters of 16 spring wheat varieties grown at two environments (Qinghai Plateau and Gansu Loess Plateau )were studied. The characters included grain protein content, flour yield, SDS sedimentation value, flour water absorption, development time, stability time, mixing tolerance index and evaluation value. The main results were as follows; (J)) The varieties were distinctly different in quality characters in two environments; the sensitiveness of quality characters to environments was different among the varieties; some were stable in two environments. (2)) Grain protein content was not significantly different in two environments, but the dough rheological properties in Gansu Loess Plateau were belter than those in Qinghai Plateau and the Qinghai plateau environment was adverse to wheat protein quality. (:￡)) Quality breeding of spring wheat in Qinghai Plateau should be improving protein quality for steamed bread and noodles. Weak gluten wheat in Qinghai should be paid attention to. |
