| 摘 要： | 为了解春小麦籽粒硬度及其单粒硬度分布频率,采用Perten SKCS 4100型单粒谷物硬度仪对92份春小麦和21份冬小麦品种的籽粒硬度及其单籽粒分布频率进行了研究,结果表明,春小麦品种按籽粒硬度分为3类5级,硬质、混合麦和软质类型分别占参试春小麦的27.2%、54.3%和18.5%,硬质、混合和软质冬小麦分别占供试冬小麦的23.8%、28.6%和47.6%..东北春麦区以硬质为主,北部春麦区和西北春麦区则以混合类型为主.硬质麦硬度值变幅为58±18～86±16,硬度低于46和高于47的籽粒频率分别为1%～38%和62%～99%;混合麦硬度值为22±28～56±21,硬度指数低于46和高于47的籽粒分别占26%～79%和21%～74%;软质麦硬度值为1±16～40±13.硬度值低于46和高于47的籽粒分别为72%～99%和1%～28%.硬度值高于60的籽粒在90%以上的硬质品种有克旱16,硬度值低于33的籽粒频率在90%以上的软质品种有巴97-8397等5份.千粒重大于40.0g和粒径大于2.50mm的品种频率分别为20.6%和23.9%.

| Abstract: | Grain hardness and their single-kernel hardness distribution frequency for 92 spring wheat and 21 winter wheat cultivars were analyzed by Single Kernel Characterization System(SKCS).It showed that a total of 92 spring wheats were classified three types and five classes: The frequency of hard mixed and soft spring wheat were 27.2%,54.3% and 18.5%,which in winter wheat were 23.8%,28.6% and 47.6%,respectively.Among the five spring wheat regions,hard wheat shared higher percentage in the Northeast China Spring ... |
