The current system of International Code of Botanical Nomenclature was adopted in
A. 1930
B. 1975
C. 1978
D. 1982

Answer 1

Hint: Binomial nomenclature is the formal system for naming the living organisms by assigning it a scientific name which is accepted worldwide.

Complete Answer:
- There are two different systems for naming plants and animals.
- For plants,the scientific name is assigned according to the norms of ICBN (International Code for Botanical Nomenclature) and for animals,the scientific name is assigned based on the rules and regulations of ICZN (International code for Zoological Nomenclature).
- ICBN was first proposed in 1930 by Hitchcock, Sprague and Green but it was accepted in 1961. In 1975, during the 12th International Congress, ICBN was revised and the revised form was accepted in the year 1978.

Therefore the correct answer is option (C) 1978.

Additional information: The scientific name has two parts- the genus name and the species name. Universal rules for biological nomenclature are as follows;
- The scientific names are generally in Latin and are written in italics.
- The first part of the scientific name represents the genus name and the second part represents the species name or specific epithet.
- Both the words are written separately in italics and are underlined.
- The first word that represents genus name starts with capital letter whereas the species name starts with a small letter.
- Name of the author is written after the scientific name in an abbreviated form.
Eg: Mangifera indica Linn is the scientific name of mango. It denotes that mango was first described by Linnaeus.

Note: There are certain cases where the genus and species both have the same names. This type of scientific name is called Tautonym. Genus names are unique only within the kingdom. Organisms can have the same genus and sometimes even the same binomial name provided that the two organisms must belong to different kingdoms.
