The researchers studied different types of mung bean plants to see which characteristics were most closely related to seed yield. They found that plant height, pod length, and test weight were positively linked to seed yield, while days to flowering and maturity, as well as number of seeds per pod, were negatively linked. The study also showed that days to maturity, pod length, and seed yield per hectare had a strong direct impact on seed yield, while days to flowering, plant height, and test weight had a negative impact. This suggests that focusing on these specific traits when selecting mung bean genotypes can help improve seed yield.
