Questions and Answers

What is a limitation of storing seeds as germplasms?

  • Seeds can be easily dried and packed for transmission to the introduction centers and gene banks.
  • Seeds are applicable to vegetative propagated crops such as potato.
  • Seeds may be destroyed by pathogen and pest attacks. (correct)
  • Seeds occupy a relatively small space.

    • Why are seeds not suitable for maintaining some crops like cacao, coconut, and mango?

  • It is not applicable to vegetative propagated crops such as potato.
  • Seeds of these crops are very heterozygous not suitable for maintaining the same genotypes.
  • Seeds of these crops may be destroyed by pathogen and pest attacks.
  • Seeds of these crops remain viable for a limited duration due to producing large recalcitrant seeds without a dormancy mechanism. (correct)
