Genetic unit and sustainable development of agroecosystem

The author discussed the conception of sustainable development which has as a central problem the interrelations between eco- and agrosystem. The conflict between these systems results in the reduction of biovariability that is incompatible not only with development but with stability of such systems. Its increasing and quality of production are determining by features of genetic unit, and here the genofonds of agricultural species of plants and animals make principal contribution. The author marks the barest necessity of studying these genofonds for a development of genetic grounded programs of the use, the perfection and the conservation of intraspecies biodiversity of agricultural species.
