Crop variety improvement

Crop variety can be improved by utilizing following methods:

  • Finding a good yield crop
  • Hybridization: The process of interbreeding between geneticallydivergent plants.

  • Introducing a gene to genetically modify the crops by providing desired characteristics to the crops.
  • Good quality seeds must be provided to the farmers.
  • Taking care to prevent the biotic factors(diseases, insects and nematodes) andabiotic factors (drought, salinity, waterlogging, heat, cold and frost) that can affect the crop growth.
  • Shorter maturity of the crops results in more economical variety.
  • Attempts must be taken to ensure higher yield.
