______ propounded the concept of centres of origin of cultivated plants.

Answer 1

Nikolai lvanovich Vavilov propounded the concept of centres of origin of cultivated plants.

Explanation:

Nikolai Ivanovich Vavilov made an inventory of diverse forms of important cultivated plants and their distribution worldwide. Vavilov distinguished primary and secondary gene centres, proposing that many important crops had multiple origins. These centres of origin are critical in understanding plant evolution and biodiversity, as they are regions where crops originated and show great genetic diversity.
