We consider the Darboux type transformations for the spectral problems
of supersymmetric KdV systems. The supersymmetric analogies of Darbou
x and Darboux-Levi transformations are established for the spectral pr
oblems of Manin-Radul-Mathieu sKdV and Manin-Radul sKdV. Several Backl
und transformations are derived for the MRM sKdV and MR sKdV systems.
