二棱大麦穗轴每节片上仅中间小穗结实,侧小穗发育不完全,均不结实,穗扁平,籽粒大小比较一致,粒大饱满,是酿造啤酒的好原料。据观察二棱大麦在品种间和穗上不同部位问籽粒性状仍有明显差异,不同程度上影响了麦芽品质。为进一步明确这种差异的程度及性状间的相互关系,为培育理想的啤酒大麦品种提供依据,我们对二棱大麦穗粒性状进行了初步研究。一、材料与方法参试品种有省农科院稻麦所和莆田市农科所提供的二棱大麦品种(系)福引1号、莆辐大麦、莆大麦2号、莆大麦4号、82-3005、82-5006、82-5015、82-5017、82-5018、82-5019和早熟3号(对照)等11 Two sides of the barley bark each spikelet mid-section of the film is strong, incomplete development of the side spikelets, are not strong, flat ear, grain size more consistent, full grain, brewing beer is a good raw material. It was observed that two-rowed barley in different parts of the grain and spike asked grain traits are still significant differences, to varying degrees, affect the malt quality. In order to further clarify the extent of this difference and the correlation between the traits, we provided a basis for cultivating the ideal beer barley varieties. I. Materials and Methods The tested cultivars were Dali Barley, Po Fu Barley, Po Barley 2, Po Barley 4, 82 -3005, 82-5006, 82-5015, 82-5017, 82-5018, 82-5019 and precocious 3 (control), etc. 11
