Question

What type of plant is formed when colchicine is used in the process of development of Raphanobrassica? (A) Triploid (B) Haploid (C) Autotetraploid (D) Allotetraploid

Colchicine (C22H25O6N) is used to induce polyploidy. Raphanobrassica (4n=36) was produced by GD Karpechenko (1927) by crossing radish (Raphanus sativus, 2n=18 ) and cabbage (Brassica oleracea, 2n=18 ). It is the first allotetraploid.

Colchicine $(C_{22} H_{25} O_{6} N)$ is used to induce polyploidy. Raphanobrassica $(4 n = 36)$ was produced by GD Karpechenko (1927) by crossing radish (Raphanus sativus, $2 n = 18$ ) and cabbage (Brassica oleracea, $2 n = 18$ ). It is the first allotetraploid.
