Which of the following is a method of breeding plants by crossing two different varieties?
Explanation
Cross-pollination is the process of breeding plants by transferring pollen from the flower of one plant to the flower of another plant of a different variety. This method is used to produce hybrids that may have desirable traits from both parent plants, such as increased disease resistance, improved yield, or enhanced nutritional content. Cross-pollination is a natural process but can also be facilitated by human intervention in plant breeding programs.
