- A farmer prefers asexual reproduction when they want to produce a large number of plants that are genetically identical to a parent plant with desirable qualities, such as high yield, disease resistance, or good fruit quality. This method ensures that the offspring retain all the beneficial traits of the parent.
- Asexual methods like cutting, grafting, layering, or tissue culture are also preferred for quick and uniform production of crops.
- Sexual reproduction is preferred when the farmer aims to introduce variation in plants. This is useful for developing new varieties, improving adaptability to changing environmental conditions, or creating disease-resistant strains through cross-breeding.
