Question

Polyembryony can be used to raise

• A. Virus-free clones
• B. Non-parental type seedlings
• C. A single embryo in the embryo sac
• D. All of the above

Answer 1

The correct option is A

Virus-free clones

Polyembryony is the formation of more than one embryo from a single fertilised ovum or in a single seed. Polyembryony is of great significance in horticulture and plant breeding. We know that in vegetative propagation new plants obtained can be considered as a clone of the parent plant. Similar to this polyembryony also produces uniform seedlings of the parental type. The clones formed are also free from diseases. In fact polyembryony is the only practical approach to raise virus-free clones.
