应用简单相关、回归分析、偏相关、通径分析方法对沪麦4号等10个啤用二棱大麦品种（系）的产量构成因素进行统计分析和研究，结果表明，3个产量构成因素对单株产量均有正向效应，其中以每株穗数的贡献最大，每穗粒数次之，千粒重贡献最小。因此，提出了高产优质啤用二棱大麦的育种模式：以增加每株穗数“多穗型”为主要选择目标，兼顾每穗粒重，增加千粒重为配合选择指标，并适当协调好千粒重与穗粒数的关系。
Using simple correlation, regression analysis, partial correlation and path analysis method, the yield components of 10 beer barley varieties (lines) including Humai No.4 were statistically analyzed and studied. The results showed that the three yield components The yield per plant had a positive effect, of which the contribution of panicle per panicle was the largest, the panicles per panicle was the least, and the 1000-grain weight contributed the least. Therefore, the breeding mode of high-quality and high-quality beer with two-rowed barley was put forward. The main objective was to increase the number of spikelets per panicle, taking into account the grain weight per spike and increasing the 1000-grain weight as the selection index, The relationship between grain number.
