摘要
播期不仅对大麦品种（系）的产量及相关性状的表现有重要影响，而且会造成性状之间相互关系的变化和差异。这种差异可大体分为两种类型：一是在三个播期下性状之间相关的方向一致，但彼此关联的程度不同；二是在不同播期下性状相关的方向或性质发生了变化。因此，要根据不同育种目标或选择不同类型品种的需要，对性状之间的关系进行相应的研究，制定性状选择的合理模式，培育出理想的品种。
According to the results of this experiment, sowing time not only affected Performances of the barley cultivars yield and related characters, but also led to the change and difference of character correlations. In general,these differences could be classified into two types: first, while the direction of correlations remained Same amomg three of different sowing time, the degree of correlations changed; second, even the direction or nature of correlations varied with the change of sowing time. Therefore, the research of character correlation should be connected with the specific objectives and characteristics of different cultivars, so as to work out the reasonable selection model and breed desirable cultivars.
