After brief introduction I will discuss the neutrino puzzles and problem of fermion flavor within \\\\nuMSSM and beyond. The simple textures for neutrino mass matrix, which give prediction for third leptonic mixing angle, will be presented. Then the main ingredients needed for generation of suggested textures will be outlined. Finally, realization of presented ideas will be discussed on example of supersymmetric SO(10) Grand Unified model. The latter, supplemented by Abelian flavor symmetry, provides a simple understanding of the observed hierarchies in the charged fermion sector including CKM mixings. In the neutrino sector bi-large mixing can be realized, while the third leptonic mixing angle is in a range 0.01-0.2.
