Hybrid clover (Trifolium hybridum L.) is one of the main legumes for meadow grass mixtures. One of the important research methods is the assessment of the plasticity and variance of its stability of variety samples, which was carried out according to the method S. A. Eberhart, W. A. Russel, V. Z. Pakudina and L. M. Lopatina. An assessment of the adaptive potential of new samples of clover hybrid selection of the Institute of agriculture of the Carpathian region NAAS was carried out. The results of a study of 26 samples of hybrid clover in terms of ecological parameters of plasticity and stability under the influence of environmental changes are presented. Revealed valuable genetic sources with high rates of basic traits.
