The researchers studied different traits in sorghum plants to see which ones are most important for increasing grain yield. They looked at things like plant height, leaf size, and how long it takes for the plant to flower. They found that the weight of 100 grains is strongly linked to higher grain yield. Traits like leaf width, panicle length, and seed weight directly affect how much grain a plant produces. This means that focusing on these specific traits could help improve sorghum yield in the future.
