The Application of Biotechnologies to Groundnut, Arachis hypogaea L., with Special Reference to Developing Countries uri icon

abstract

  • Groundnut is the twelfth most important crop in the world, occupying some 19 millionhectares in the warm temperate and tropical zones bounded by the 400 line of latitude. it isusually grown under rainfed conditions, but there are some areas in which it is grown underirrigation. World production in 1987 was 20 million tonnes in shell, most of which (12.8million tonnes) was produced in Asia; of this amount, China produced 6.1 million tonneswhile India produced 4.5 million tonnes. Africa produced 4.7 million tonnes. Worldwide,average yields by country range from 0.43 tonnesha to 4.60 tonnestha (FAO. 1987). Rainfedcrops are often grown under low-input conditions, and even in those developing countrieswhere fertilizers and pesticides are available on the market, many small farmers do not havesufficient resources to make use of them. There is thus a strong incentive todevelop varietieswith pest and disease resistance, tolerance to poor soils, and the ability to yield under lowmoistureregimes
