New collection varieties of creeping clover (Trifolium repens L.) from the VIR collection of the 1970s were studied. Samples were evaluated according to the main morphological and biological characteristics, seed productivity and chemical indicators. After 50 years of storage under natural conditions, the samples had up to 71% of germinating seeds (31% of germinated + 40% of hard seeds). As a result of the study of collection variety samples, valuable sources for selection were identified, which allowed the best genotypes to be included in hybridization for the construction of hybrids with high feed and seed productivity. It is noted that in the State register of selection achievements, varieties of clover creeping foreign breeding make up 67%.
