The recent development of ideas on biodiversity conservation was
already being considered almost three-quarters of a century ago for
crop plants and the wild species related to them, by the Russian
geneticist N. . Vavilov. He was undoubtedly the first scientist to
understand the impor tance for humankind of conserving for
utilization the genetic diversity of our ancient crop plants and
their wild relatives from their centres of diversity. His
collections showed various traits of adaptation to environ mental
extremes and biotypes of crop diseases and pests which were unknown
to most plant breeders in the first quarter of the twentieth cen
tury. Later, in the 1940s-1960s scientists began to realize that
the pool of genetic diversity known to Vavilov and his colleagues
was beginning to disappear. Through the replacement of the old,
primitive and highly diverse land races by uniform modem varieties
created by plant breed ers, the crop gene pool was being eroded.
The genetic diversity of wild species was equally being threatened
by human activities: over-exploita tion, habitat destruction or
fragmentation, competition resulting from the introduction of alien
species or varieties, changes and intensification of land use,
environmental pollution and possible climate change."
