The researchers studied the relationship between different traits and grain yield in rice plants. They looked at 10 traits like plant height, grain length, and number of panicles per plant. They found that plant height, panicle length, and number of panicles per plant were important for high grain yield. They also discovered that the number of filled grains per panicle had a big impact on grain yield. By analyzing the data, they found that certain traits like plant height and number of filled grains per panicle could help improve grain yield in rice plants.
