| 摘 要： | 为了解引进大麦品种资源的特性并为进一步利用提供依据，以从日本引进的儿9份大麦种质为材料，对不同棱型大麦的株高、穗下节间长、穗长、穗粒数、千粒重和产量等6个农艺性状进行了测定及统计分析。结果表明，不同棱型的材料在这6个性状上有明显的差异，其中株高、穗长、穗粒数、千粒重4个性状差异显著。与四棱和六棱相比较，二棱材料极显著地表现出矮秆、穗下节间长度短、穗子长、穗粒数少、千粒重大的特点；四棱材料株高、穗长、穗粒数、千粒重居中，产量显著高于其它类型；六棱材料穗粒数极明显地高于其它棱型。

| Abstract: | Six characters such as plant height, node length under spike, spike length, grain number per spike,1000-grain weight and yield were measured and analysed by statistic method. The result showed that there are obvious difference among different row-type based on these six characters. Compared with four-row and six-row, tow-row type presents short plant height, node length under short spike, long spike, less number of grain in a spike and heavy grain. The plant and yield four-row type are the highest, but the spike length,the number of grain in a spike as well as the weight of grain is in the middle and the number of grain in a spike of six-row type is the highest. |
