Conservarea in situ a agrobiodiversității vegetale – factor de reușită în promovarea agriculturii durabile

The article gives brief information on inventorying of some crop wild relatives in the forest ecosystems of different soil-climatic zones of Republic of Moldova, and collection of accessions of the local forms of cultivated plants on farms. It was found that natural populations of 5 pilot species – wild cherry, wild pear, cornelian cherry, wild apple and hazelnut are degrading under the influence of envi-ronmental stresses. It is noted that the range of social-economic and political factors of the past 60-70 years has led to significant genetic erosion of the local gene pool of agricultural crops. Elaboration of the effective methods for in situ conservation of agrobiodiversity will facilitate the greening of agricultural production and introduction of the elements of sustainable agriculture.
