摘  要:
为了拓宽小麦品质育种遗传资源,对27份圆锥小麦地方品种的面筋和面团流变学特性进行了分析。结果表明,供试品种间存在较大差异,其面筋指数平均为63.02%,变幅为23.58%~99.78%;湿面筋含量平均为41.19%,变幅为30.21%~49.66%;干面筋含量平均为13.07%,变幅为10.09%~15.77%;蛋白质含量平均为13.80%,变幅为10.11%~16.06%。其粉质仪参数表现为吸水率较高,形成时间、稳定时间和断裂时间较短,公差指数表现一般与形成时间和稳定时间均值分别为3.1 min(变幅为1.2~7.5 min)和3.9 min(变幅为0.6~11.4 min)。蛋白质与湿面筋和干面筋含量之间表现为极显著正相关,与形成时间呈显著正相关。面筋各参数相互之间,以及粉质仪各参数相互之间存在不同显著程度的相关,但两类参数之间相关不显著。分析表明圆锥小麦地方品种中可能具有普通小麦品质改良所需的优异基因资源,对于品质育种具有重要利用价值。

摘  要:
In order to exploit the gene resources for quality breeding of wheat.The glutenin and farinograph parameters of 27 turgidum landraces were investigated.The results showed that higher variation of these traits had been observed.The means of gluten index,wet gluten,dry gluten and protein content were 63.02 %(23.58 %~99.78 %),41.19%(30.21 %~49.66 %),13.07% and 13.45%(10.11 %~16.06 %),respectively.Higher water absorption,shorter dough development,shorter stability and breakdown time were also observed.The average development and stability time were 3.1 min(1.2 min~7.5 min) and 3.9 min(0.6 min~11.4 min),respectively.Protein content was significant correlation with wet gluten and dry gluten(p<0.01),and development time.Furthermore,there was no significant correlation between glutenin and farinograph parameters in trugidum landraces.These results suggested that there might exist some desirable gene resources in turgidum landraces,which were very useful for quality breeding of common wheat.
