Abstract. This article shows the statistical characteristics of the new parent material according to the main morphological features: plant height, technical stem length, stem diameter and panicle length. It contains a correlation and regression analysis of the relationships between the height of plants and the technical length of stems, their diameter and the length of the inflorescence. As a result, the general parameters and the nature of the variability of the main morphological features of the new seed hemp parent material were established. It is shown that the feature "plant height" has a strong correlation with the technical length of the stem and its diameter. For breeding practice, it is recommended to carry out the primary selection of breeding material on the basis of "plant height". The selection should be carried out among a set of forms in which, according to the results of statistical analysis, the values of plant height are located in the positive region of three times the standard deviation from the average value of the trait. The potential effectiveness of the selection is justified by the fact that the technical length and diameter of the stem determine the yield of the fiber.
Keywords: seed hemp, parent material, morphological features, hybridization, plant height, technical stem length, stem diameter, inflorescence length.
