Rice ratooning cultivation refers to a secondary production from the stubble left after the harvest of main crop (MC). Besides the additional production, ratooning is known to affect grain quality. Here, we conducted meta-analysis of grain quality between ratoon season crop (RC) and MC. The results showed the overall grain quality of RC was higher than MC. Ratooning benefits milling traits by increasing milled rice rate (MRR) and head rice rate (HRR), improves grain appearance by reducing the chalkiness. Furthermore, ratooning has a positive impact on alkali spreading value (ASV) and amylose content (AC) but a negative influence on gel consistency (GC), which remarkably impacts the cooking and sensory quality. Subgroup analysis showed stubble heights influence the AC of RC, while planting region is a major factor regulating most of the grain properties. Meta-regression analysis suggested latitude, precipitation, and temperature played important roles in rice quality, especially on the milling parameters. In addition, the grain quality was compared between RC and the late season crop (LC) with synchronized heading time. Negative trends on brown rice rate (BRR) and protein content (PC) was observed, while planting region and rice varieties were revealed as factors for the impact on chalkiness and HRR. Overall, our findings provide ratooning has positive impacts on grain quality and uncover the relationship between impacting factors and their effects on quality traits, which will lay the foundation for future breeding strategies and optimize cultivation management in various growth regions.
