(a) Higher yield: It helps in the production of crop.
(b) Biotic and abiotic resistance: Crop should be resistant to biotic factors like
diseases, insects, pests and abiotic factor like-drought, salinity, heat,
cold, frost and water logging.
(c) Change in maturity duration :
Short-duration maturity allows farmer to grow more crops in a year and
reduces the cost of crop production.
(d) Wider adaptability: Crop should be able to adapt to changing environmental conditions.
(e)
Desirable agronomic characteristics: The tallness and dwarfness of crop.
Dwarfness required for cereals, so that less nutrients are consumed.
