Question

ICBN was adopted in
A) 1951
B) 1978
C) 1971
D) 1961

Answer 1

Hint: ICBN stands for International code of botanical nomenclature. It is the set of instructions used in naming the plants.

Complete Answer:
- The system of binomial nomenclature was first suggested by linnaeus. He suggested the system so as to have a universal name of all the species. It consists of two names.
- The first word is the genus name and the second is the species name.
For eg Mangifera indica- biological name for mango. Here Mangifera is the genus and indica is the species name.
- ICBN is the set of rules and recommendations which deal with the formal botanical name given to the plants. ICBN was adopted in 1961.
- It not only applies to the plants but also to other organisms like algae, fungi. The botanical names are independent of zoological and bacteriological nomenclature.
- The application of the names of taxonomic groups is determined by the nomenclature types. Each taxonomic group can bear only one unique name that is in accordance with the rules.
- The scientific names of taxonomic groups are treated as Latin regardless of their derivation. The change in the code of nomenclature is very limited. All the proposals to change the code are published in Taxon.

Thus the correct answer is (D) ICBN was adopted in 1961.

Note: Nomenclature, in biological classification, system of naming organisms. The binomial nomenclature of plant species is different for other organisms.
