Hedysarum grandiflorum samples were collected from 7 natural populations of the Volgograd, Samara and Lugansk People's Republic and the features of seed reproduction were studied under ex situ and in vitro conditions. The optimal temperature for seed germination and the dependence of germination and seed vigor on the storage were revealed. We observed the maximum germination rate in the scarified seeds of H. grandiflorum of 2018 collection and it was equal to 70%.It was found that the seed germina-tion and seed vigor are low and quickly decrease with years of storage, while their scarification allows to increase these indicators. It is noted that the relatively low germination of the studied seeds is leveled by the rather high productivity of species in general. The optimal mode of sterilization of H. grandiflorum seeds was experimentally determined - 10% Lysofornin® 3000 solution for 5 minutes. The percentage of sterile seedlings was 60%.
