Extended Data Fig. 5: Grain yield and agronomic traits of perennial rice cultivar PR25 over three years at six locations.
From: Sustained productivity and agronomic potential of perennial rice
a, Grain yield (Mg ha−1). b, Duration (d). c, Plant height (cm). d, Regrowth rate (%). e, Panicle number m−2. f, Spikelet number panicle−1. g, Grain weight (mg). h, Seed setting rate (%). Field trial locations were double cropping paddy areas in Jinghong (21°59′ N, 100°44′ E, 550 m), Menglian (22°33′ N, 99°59′ E, 960 m), Mengzhe (21°57′ N, 100°14′ E, 1,255 m) and Xinping (24°02′ N, 101°34′ E, 600 m) and single cropping paddy areas in Wenshan (23°23′ N, 104°13′ E, 1,260 m) and Yiliang (24°54′ N, 103°09′ E, 1,600 m). F1–F3 represent the first seasons of years 1–3. S1–S3 represent the second seasons of years 1–3. The data are means from Experiment 4, with l.s.d. for these traits being: a) 1.2; b) 17; c) 8; d) 7; e) 56; f) 14; g) 2; and h) 7 (N = 63; P < 0.05) (see Supplementary Table 5).
