The study looked at different traits in 26 types of rice plants to see how they are related and which ones are important for improving crop yield. They found that traits like the number of panicles and tillers per plant are good indicators for selecting better crops. The number of spikelets per plant is highly heritable and can help increase yield. They also discovered that traits like days to flowering, plant height, and number of grains per panicle directly affect grain yield. Overall, these findings can help farmers choose the best rice plants to grow for higher yields.
