The study looked at how different traits in pumpkin plants are related to each other and affect fruit yield. They measured things like vine length, fruit weight, and sugar content to see which factors were most important for a good harvest. The researchers found that the number of fruits per plant and vine length had the biggest direct impact on fruit yield. This means that having more fruits on a plant and longer vines can lead to a higher yield of pumpkins. They also discovered that certain traits, like the time it takes for flowers to appear, can have a negative effect on fruit yield. Overall, the study showed which characteristics are key for growing lots of pumpkins successfully.
