  Aiming to relate leptonic CP violating phase $\delta $ to the cosmological CP
asymmetry, we study the extension of MSSM by two quasi-degenerate (strictly
degenerate at tree level) right-handed neutrinos and consider all possible two
texture zero 3x2 Yukawa matrices plus one $\Delta L=2$ dimension five (d=5)
operator contributing to the light neutrino mass matrix. We classify all
experimentally viable mass matrices, leading to several predictions, and
analytically derive predictive relations. We also relate the CP violating
$\delta$ phase to the CP phase of the thermal leptogenesis.
