What is polyembryony and how can it be commercially exploited?

(N/A) The occurrence of more than one embryo in a seed is referred to as polyembryony.
In many citrus and mango varieties,some of the nucellar cells surrounding the embryo sac start dividing,protrude into the embryo sac,and develop into embryos. In such species,each ovule contains many embryos.
Polyembryony plays a major role in plant breeding and horticulture.
The plants obtained from these embryos are typically virus-free and exhibit vigorous growth.
Many fruit and vegetable crops are propagated using this method,as these nucellar embryos produce clones that maintain the desirable traits of the parent plant,leading to higher productivity and uniformity in hybrid crops.
