【摘要】 采用典型相关对啤酒大麦Ｆ２代群体的５个产量性状和８个形态性状进行分析，结果表明，穗粒数、千粒重对单株产量的提高有促进作用；单株穗数、叶片数、旗叶面积与单株产量亦密切相关；株高、穗长对穗粒数有正向效应；株高、芒长、主茎节数，叶片数利于提高单株穗数与穗粒重，其它性状作用甚微。综合分析得出：单株穗数多、穗粒数多、千粒重高、半矮秆、叶片数多、旗叶面积大的类型，可作为啤酒大麦Ｆ_２代单株选择模式。更多还原

【Abstract】 By means of the methed of typical correlation analysis, 5 characters of the yield and 8characters of the shape of malting barley in F2 generation have been studied. The reults showed:the grain numbers of per ear and the kilograins weight have more promoting function for raising single plant yield; The ear number per plant,the number of leaf,the area of the top leaf and single plant yield are very close correlation;The height of the plant and the ear length are the positive effects to the grain numbers of per ear; The height of plant,the length of awn,the knots of main stem,the numbers of leaf can raise the ear numbers of per plant and the grain numbers of per ear;The other characters’ effects are very small. Synthetical analysis showed: More ear numbers of per plant, more grain numbers, high kilograms weight,the half low of plant,more numbers of leaf,the larger area of the top leaf types are selected for selection model in F2 generation single plant.更多还原
