The study looked at different types of potatoes to see how they vary in characteristics like yield and plant height. They found that there were significant differences among the potato types for most traits. The potato types had the most variation in tuber yield, plant height, leaf area, plant spread, and average tuber weight. The researchers also found that most of the traits had high heritability, meaning they can be improved through breeding. Overall, the study showed that there is potential to enhance these potato traits through genetic methods.
