a, Cultivation of PR globally. b, Cultivation of PR in China. c, Number of production locations and cumulative area of PR production in China since 2011. As PR107 and PR25 were released in 2020, the data for cultivation area are mostly for PR23. The least significant difference (LSD) for location and area were 5 and 4, derived from LSD for log(location) and log(area), respectively (P < 0.05) (Supplementary Table 7). d, Grain yield of PR23 over five years with ten successive seasons between 2016 and 2020. F1–F5 represent the first seasons of years 1–5; S1–S5 represent the second seasons of years 1–5. The LSD for grain yield was 1.7 Mg ha−1 (P < 0.05), with the data derived from Experiment 3 (Supplementary Table 4 and Extended Data Fig. 4).
