Researchers studied 44 types of paprika to understand the genetic differences in traits like fruit size and yield. They found that most traits had high genetic variability, meaning they can be easily improved through selection. Traits like number of fruits per plant and seed weight showed the most potential for improvement. These traits also had high heritability, meaning they are mostly controlled by genes and not influenced by the environment. This suggests that simple selection methods can effectively enhance these traits in paprika plants.
