通过对夏谷主要数量性状之间及其与产量的关系进行研究，结果表明：出谷率、单株粒重对产量的影响较大；单株穗重与单株粒重、单株秆重呈显著正相关，与植株高度呈极显著负相关，为杂种后代的选择提供了依据。
Through the study of the relationship between the main quantitative traits and the yield of summer cereal, the results showed that: the valley rate and the grain weight per plant had a great effect on the yield; the ear weight per plant and the grain weight per plant, the culm weight per plant Significant positive correlation with plant height was significantly negatively correlated, providing the basis for the selection of hybrid offspring.
