Researchers studied dolichos bean plants to understand which traits directly affect the yield of fresh pods. They found that traits like the number of fresh pods per vine, fresh pod shelling percentage, and average weight of fresh pods have a strong positive impact on pod yield. Additionally, traits like fresh seed yield per vine and number of seeds per fresh pod also play a significant role in determining fresh pod yield. These findings suggest that focusing on these specific traits can help increase the overall yield of fresh pods from dolichos bean plants.
