It is shown that the nonabelian p-groups all o f whose proper subgroups have a derived subgroup of
order equal or less then p for p > 2 is either groups with commutator subgroup o f order p or groups,
which are either 2-generated group from isoclinism families Ф3, Ф6. Ф8. Ф14 or 3-generated groups
from isoclinism families Ф4, Ф11. The misprints and mistakes o f a previous paper are corrected.
