Vavilovian Centers of Diversity

Vavilovian Centers of Diversity

  • N. I. Vavilov (1926, 1951), a Russian geneticist and plant breeder, was the pioneer man who realized the significance of genetic diversity for crop improvement. Vavilov and his colleagues visited several countries and collected cultivated plants and their wild relatives for use in the Russian breeding programme to develop varieties for various agro climatic conditions of USSR.
  • Based on his studies of global exploration and collection, Vavilov proposed eight main centres of diversity and three subsidiary centres of diversity given as follows
    1. Main centres-
  • Main centres of crop diversity as proposed by Vavilov are (1) China, (2) India (Hindustan), (3) Central Asia, (4) Asia Minor or Persia, (5) Mediterranean, (6) Abyssinia, (7) Central America or Mexico, and (8) South America.
    2. Subsidiary Centers -
  • There are three subsidiary centres of diversity. These are: (1) Indo-Malaya, (2) Chile, and (3) Brazil and Paraguay.
  • All these centres are known as centres of origin or centres of diversity or Vavilovian centres of diversity.
  • Vavilovian centres of diversity of crop plants
