Aim. Detailed examination of different studies showed that the thickness of the straw second internode of soft winter wheat is not sufficient investigated. Methods. The article presents the results of an experiment for the study of the formation and the variability of the trait thickness of the straw second internode (TS-2M) in different soft winter wheat (Triticum aestivum L.) varieties and breeding lines. There are forty one wheat varieties of different origin presented in this study. Results. It was established that the trait TS-2M significantly correlated with the main yield traits. Therefore, the selection of productive genotypes in the selection process based on TS-2M is effective. Conclusions. The statistical analysis of winter wheat varieties based on the trait TS-2M showed that the level of formation and variability of this trait is genetically determined.

Keywords: winter wheat, the second internode (ТS-2М), genetic coefficient of variation (CV%).
