How do you obtain a pure-bred plant?

To obtain a pure-bred plant, you can use methods like self-pollination or controlled cross-pollination within the same variety to ensure genetic consistency. Start with a plant that exhibits the desired traits and repeatedly breed it with itself over several generations, allowing for the selection of offspring that express those traits consistently. It's also important to maintain proper growing conditions and isolate the plants from other varieties to minimize cross-contamination. Finally, molecular techniques such as DNA analysis can help confirm the purity of the breed.
