This article presents the results of research conducted in 2018 and 2019 in the conditions of the south-east of the Central Chernozem Region. We have studied various morphotypes of millet: varieties with a spreading and compressed panicle, with erect and drooping leaves, with a drooping and erect panicle, with a short and long upper internode, with red and yellow grain. A correlation analysis of 50 varieties of different morphotypes (according to Spearman and Pearson) between economically valuable traits was performed. According to the results of correlation analysis, the relationship between economic and valuable signs in different morphotypes is shown. The most promising morphotype for selection of varieties adapted to the conditions of the Central Chernozem region is identified. These are red-grain millet varieties with a compressed panicle shape, with erect leaves, with a long upper internode, with a weak droop of the panicle. These varieties were characterized by the most valuable economic and useful features. An example of this variety is the new millet variety Stepnoe 9, zoned according to the Central Chernozem Region since 2018. This variety belongs to the sanguineum variety (compressed panicle, red grain), has erect leaves and panicle, and a relatively long upper internode.
