When creating new varieties of red clover (Trifolium pratense L.), it is necessary to use a source material characterized by an increased weight of heads and dry matter of plants, an abundant number of stems and heads, seeds in the heads, high rates of seed setting and seeding of inflorescences due to their strong and average correlation with seed productivity (r = 0,57-0,89). The length of the stems, the weight of 1000 seeds, and the fullness of the severity of the pattern on the leaves had a close to average and average correlation with seed productivity. (r = 0,24-0,46). The number of internodes of the stem, the number of pods in the heads, the duration of the period from the beginning of spring regrowth to the beginning of flowering, the two-seeded pod also had a positive correlation with seed productivity, although to a lesser extent (r = 0,04-0,24). The revealed correlations can be used in the selection of red clover in the selection of initial material and rejection of selection numbers in order to increase the efficiency and reduce the time of the selection process.
