Genetic manipulation helps in obtaining desirable agronomic characters liked Dwarfness in cereals and tallness and profuse branching in fodder crops. It is useful in developing varieties with higher yield, good quality, biotic and abiotic resistance, short maturity period, wider adoptability and desirable agronomic characteristics.
