The circadian mitotic rhythms in representatives of soybean Glycine max (L.) Merr., G. soja Sieb. & Zucc., as well as in homozygote forms of tibia F6 hybrids were studied. We observed three "waves" of the mitotic activity in the cells of apical root meristem with the initial moment of the perfect rest at 24 o’clock; and the legible periods which decreased later on. Beginning from 1 o’clock to 6 o’clock the first maximum mitotic "wave" increased; the second one evolved up to 12 o’clock, the third less legible one arised at 18-21 o’clock. Each of soybean tested forms was distinguished by the peculiarity in periodical processes and the values of mitotic indexes
