Question

Name the tissue culture technique used to grow non-viable inter-specific hybrids.

• A. Androgenic haploids
• B. Shoot tip culture
• C. Somatic embryogenesis
• D. Embryo rescue

Answer 1

The correct option is D Embryo rescue

Embryo rescue refers to the culture of the immature embryo to produce viable individual. Interspecific hybridization wherein two individuals of two different species are crossed, experiences many pre- and post-fertilization barrier that inhibits successful gene transfer. The post fertilisation barriers that result in starvation and abortion of hybrid embryo are overcome by isolation and culture of the immature embryo before abortion i.e., embryo rescue.

Thus, the correct answer is option D.
