Haploid tomato plants have been successfully regenerated via anther culture by_________________?
Show answer Hide answer
Answer: A. Greshof and Doy (1972)
Explanation
Plant tissue culture pioneers successfully regenerated haploid tomato plants using anther culture techniques. Researchers Gresshoff and Doy achieved this significant scientific milestone in the year 1972. Their breakthrough experiments demonstrated that microspores could develop into complete haploid plants in vitro. Anther culture involves cultivating immature anthers on nutrient media to induce androgenesis from pollen grains. Haploid plants contain a single set of chromosomes and are invaluable tools for rapid plant breeding programs. Historical breakthroughs in plant biotechnology laid the groundwork for modern doubled haploid line development.
Plant breeders use haploid regeneration to homozygous lines instantly, bypassing generations of traditional inbreeding. Reading historical scientific literature provides important context on how modern tissue culture protocols evolved. Tomatoes serve as a model organism for genetic and physiological research across global scientific laboratories. Tyagi and Prasad represent different researchers who did not perform this specific 1972 anther culture milestone. Mehta and Upadhya worked on other plant science topics rather than this specific tomato haploid regeneration. Singh is a common surname and does not correctly identify the pioneering researchers for this discovery.
