New relations between the Borel QCD sum rules for the strong couplings of the {sigma}{sup 0} and {lambda} hyperons are derived. It is shown that, using the sum rules for g{sub M{sigma}}{sub {sigma}}, M = {pi}{sup 0}, {eta}, as a starting point, one can readily obtain the corresponding sum rules for the coupling constants g{sub {eta}}{sub {lambda}}{sub {lambda}} and g{sub {pi}}{sub {lambda}}{sub {sigma}}{sup 0}. The values of these constants are calculated in a specific parameter region.
