Yermishin, A.P. (Genetics and Cytology Inst., NASB, Minsk (Belarus))
Available information is analysed about mechanisms of prezygotic incompatibility during interspecific and intraspecific hybridization of diploid potato and approaches are proposed to overcome it. The types, evolution, models, modern molecular and biochemical data on the nature of gametophytic incompatibility are discussed. The model was further developed, based on the common mechanism of inter- and intraspecific incompatibility. This model makes it possible to explain different cases of intra-, interspecific and unilateral incompatibility, the mechanisms of action of methods used to overcome it. New approaches for circumventing interspecific incompatibility barriers are discussed. These are diploid bridge-lines, produced on the basis of rare sexual interspecific hybrids or dihaploids of somatic hybrids, and also bridge-lines lacking the stylar S-RNases
