摘    要:对49份四川小麦新品种(系)的主要农艺和品质性状进行了考察。结果表明,供试材料的农艺性状普遍表现优良。蛋白质含量中等偏低,平均为12.97%。沉降值属中、低水平,平均为22.23 mL。面筋含量较高,湿面筋含量平均为33.68%。粉质指标普遍较差,其中形成时间平均为2.01 min,稳定时间平均为3.22 min,粉质质量指数平均为35.66。大多数材料筋力为中到弱筋。从主要品质指标来看,W7达到了优质强筋小麦标准,另有4份材料达到专用中筋小麦标准,2份材料达到专用弱筋小麦标准。相关分析表明,蛋白质含量与沉降值、面筋含量、吸水率呈显著或极显著的正相关;沉降值与其它品质性状多呈显著或极显著的正相关,可作为品质育种早代选择指标;面筋指数与粉质参数多呈显著或极显著的正相关;千粒重与面筋指数、稳定时间、粉质质量指数均呈极显著的负相关。相反,其它农艺性状与品质性状的相关大多不显著,这表明高产与优质的矛盾并不是绝对的。

关 键 词:小麦  品质性状  农艺性状  相关性

Abstract:The main agronomic and quality characters were investigated in 49 Sichuan new wheat varieties and lines.Most of the wheat genotypes have the desirable agronomic characters.The protein contents of these genotypes were co mmonly medium or low,averagely 12.97 %.The average sedimentation values were 22.23 mL.The content of wet gluten were 33.68 %.The farinograph parameters were not fine,for example,on average the developing time was 2.01 min,Stability time was 3.22 min and the farinograph quality number was 35.66.According to the main quality indexes,W7 accorded with the standard of high quality,strong gluten wheat,other 4 genotypes reached the standard of special,medium gluten wheat and 2 materials accorded with the standard of special,weak gluten wheat.The correlation analysis results showed that the protein content had significant positive correlation with sedimentation value,gluten content and water absorption,respectively. Sedimentation value had significant positive correlations with other quality characters.There were significant positive correlations between gluten index and farinograph quality parameters.The 1000 grains weight was negatively significant correlated to the gluten index,stability time and the farinograph quality number.No significant correlations were detected between most of the other agronomic characters and quality ones,which indicated that the breeding aims of high yield and good quality were not conflicted.
Keywords:wheat  agronomic characters  quality characters  correlations
