陇育号小麦品种（系）粉质特性研究

粉质测定是研究小麦及面粉内在品质的重要方法之一,通过粉质测定方法研究陇东学院育成的8个陇育号冬小麦品种的粉质特性。结果表明：该8种陇育系列小麦吸水率平均值为63.9%,变幅为60.4%—71%;形成时间平均值为2.3min,变幅为2—3min;稳定时间平均值为1.5min,变幅为1.1—1.9min;弱化度平均值为184,变幅为131—253,公差指数平均值为140,变幅为101—188;粉质指数平均值为33.7,变幅为26—41。这些品种均为低筋粉,不适合做优质面包也不适合做优质饼干,因此需通过引进优质高筋小麦对其品质改良,为育种工作提出理论依据。

Studies on Farinogram Parameters of Wheat Cultivars-Longyu hao

Farinogram determination is one of the important methods to study the inherent quality of wheat and flour.We used farimogram determination to research the farinogram parameters of 8 winter wheat cultivars-Longyu hao which were bred by Longdong university.The results indicated that the average of water absorption of 8 wheat cultivars-Longyu series was 63.9% and amplitude of variation 60.4% —71%,the average of formation time 2.3min and amplitude of variation 2—3min,the average of stabilization time 1.5min and amplitude of variation 1.1—1.9min,the average of weakening 184 and amplitude of variation 131—253,the average of tolerance index 140 and amplitude of variation 101—188,the average of farimogram index 33.7 and amplitude of variation 26—41.These were all low-gluten flour,which were neither suitable for high-quality bread nor biscuits.Therefore,we need to improve the quality through the introduction of high-gluten wheat,which could provide theoretical basis for breeding.
