Question

Which is the oldest method for crop improvement?

• A. Hybridization
• B. Selection
• C. Mutation breeding
• D. Introduction

Answer 1

The correct option is B Selection

Plant breeding, application of genetic principles to produce plants that are more useful to humans. This is accomplished by selecting plants found to be economically or aesthetically desirable, first by controlling the mating of selected individuals and then by selecting certain individuals among the progeny. Such processes, repeated over many generations, can change the hereditary makeup and value of a plant population far beyond the natural limits of previously existing populations.

Selection is the oldest crop improvement method compared to hybridization, mutation and introduction. Thus, option B is correct.
