Question

Embryoid culture technique was discovered by

• A. Guha and Maheshwari
• B. Skoog and Miller
• C. Muir et al
• D. Steward

Answer 1

The correct option is D Steward

In 1958, F.C. Steward, M.O. Mapes & K. Mears first reported the embryoid culture of freely suspended carrot cells by somatic embryogenesis. Embryoid is a small well-organised structure comparable to the sexual embryo. It is developed from the somatic plant cells with embryogenic potential in plant tissue culture.

Guha and Maheswari developed an anther culture technique for production of double haploid cells in the laboratory in 1964.

Skoog and Miller put forth the concept of hormonal control of organ formation in plants in 1957.

Single cell culture technique was first diagrammed by Muir et al in 1954.

Thus, the correct answer is option D.
