Question

A major use of embryo culture is in _____________.

• A. Induction of somaclonal variations
• B. Overcoming hybridisation barriers
• C. Production of alkaloids
• D. Clonal propagation

Answer 1

The correct option is B Overcoming hybridisation barriers

• Hybridization barrier means limited interbreeding between two populations which reduces the variability.
• Embryo rescue or culture is a technique which allows the plant to overcome the hybridization barrier by mixing the genetic pool of two population.
• Embryo rescue or embryo culture is a technique which nurtures the immature or weak embryo, thus allowing it the chance to survive.
• Plant embryos are multicellular structures that have the potential to develop into a new plant.
• It allows the breeding of incompatible interspecific and intergeneric species and helps to overcome the hybridisation barrier.
