Question

Write a short note on embryo rescue.

Answer 1

Embryo rescue is a plant breeding technique used to save immature or hybrid embryos that would normally abort before seed maturity. These embryos are grown in vitro in a controlled culture medium, allowing the development of a complete hybrid plant. This method helps obtain hybrids that are difficult to produce naturally, such as fruit trees (peach, cherry) or crosses between cultivated and wild species. It can also shorten breeding cycles by growing embryos from normal seeds faster than usual.
