Question

The concept of “Centres of Origin of Cultivated Plants” was put forward by
A. Swaminathan
B. Mendel
C. Vavilov
D. Borlaug

Answer 1

Hint: The centers of origin of plants are fittingly called the focuses of variety. These are the regions of the most extreme variety of these species. Yield plants developed from wild species in the regions demonstrating incredible variety and named them as primary regions of root. In any case, in certain territories, certain yield species show an extensive variety of structures although they have not started from such regions which are known as secondary centers.

Complete answer:
A center of origin (or focus of variety) is a geological zone where a group of life forms, either tamed or wild, first built up in its particular properties. They are additionally viewed as focuses of variety. Centers of origin were first recognized in 1924 by Nikolai Vavilov.
Vavilov worked at the global genetic diversity of developed plants for an amazing duration, from which he built up a few significant speculations that have assumed a significant function in the advancement of herbal science, hereditary qualities, and plant rearing. One such hypothesis among a few is "Theory of centers of origin of cultivated plants".
This permits one to find wild family members, related species, and new qualities (particularly prevailing qualities, which may give protection from illnesses). Information on the inceptions of harvest plants is significant to keep away from hereditary disintegration, the loss of germplasm because of the loss of ecotypes and landraces, loss of territory, (for example, rainforests), and expanded urbanization.

Hence, the correct answer is option (C).

Additional information:
Swaminathan is called the father of the Indian Green Revolution. He has presented high-yielding assortments of wheat and rice in India. He has contributed towards the reinforcement of farming and improving food security.
Mendel completed his key tests utilizing the garden pea, Pisum sativum, as a model framework. Pea plants make an advantageous framework for investigations of legacy, and they are as yet concentrated by certain geneticists today.
Borlaug suggested improved strategies for development, and built up a vigorous strain of wheat - bantam wheat - that was adjusted to Mexican conditions. By 1956 the nation had become independent in wheat.

Note: Vavilov worked on the worldwide genetic diversity of developed plants for a life-long duration, from which he built up a few significant hypotheses that have assumed a significant function in the improvement of herbal science, hereditary qualities, and plant reproducing. One such hypothesis among a few is "Theory of centers of origin of cultivated plants". This permits one to find wild family members, related species, and new qualities (particularly prevailing qualities, which may give protection from infections).
