Discuss the two main limitations of plant hybridization programme.

Two main limitations of plant hybridization programme are:

i. Availability of desirable traits: The plant hybridization is mostly dependent on the availability of desirable traits which is to be introduced in the next generation. Hence, availability of desirable traits in existing varieties and wild variety is a limitation.

ii. Linking of desirable trait to undesirable gene: Many a times a desirable trait is linked to the undesirable trait of the plant. The extraction of desirable traits from the undesirable ones creates a limitation to this programme too.
