对小麦品种（系）茎叶性状与穗部性状进行相关性研究，结果表明：小麦茎叶性状与穗部性状之间存在不同程度的相关。其中，穗节茎粗与穗粒数、穗长、穗粒重、剑叶面积呈正相关；剑叶面积与穗粒数、穗长、穗粒重呈正相关；穗长、穗粒数、穗粒重之间呈正相关；穗节茎粗和剑叶面积与株高呈负相关。
The correlation between the stem and leaf traits and panicle traits of wheat cultivars (lines) was studied. The results showed that there were some correlations between stem traits and panicle traits in wheat. Among them, the spike stem diameter was positively correlated with the number of spikelets, spike length, kernel weight and flag leaf area; the area of flag leaf was positively correlated with the number of spikelets, spike length and spikelet weight; the spike length, number of spikelets, There was a positive correlation between weight, stem diameter and leaf area of spikelets and plant height.
