Current state of seed production system is analyzed as well as methods and technigues of its improvement. Observed and ideal curves of variety replacement are shown. Advantages of the adapted systems of the varieties which are complementary to one another; factors of variety deterioration and the methods of their elimination are discussed. A special attention is paid to registration and to support of biotypical structure of the variety, and to the loss of resistance to pathogenes in varieties. General universal criteria which determine an effective state and a progressive development of any seed production system are substantiated
