Which breeding technique involves the removal and manipulation of anthers?

• A. Self-fertilization
• B. Cross-fertilization
• C. Hybridization
• D. True-breeding

Answer: (B)

The technique that involves the removal and manipulation of anthers is primarily associated with cross-fertilization. In this method, particularly in plant breeding, the anthers— which are the pollen-producing parts of the flower— are removed to prevent self-fertilization. By doing so, breeders facilitate the transfer of pollen from one flower (or plant) to another, thereby promoting genetic diversity and hybrid vigor. Cross-fertilization is crucial for creating hybrids, as it allows for the combination of different genetic materials. This method enhances traits that may not be present in a single variety, resulting in offspring that can express favorable characteristics of both parent plants. Through the strategic removal of anthers, breeders ensure that controlled crosses can be made to achieve desired traits in the new generation.
