Extended Data Fig. 3: Changes in agronomic traits over generations of breeding perennial rice.
From: Sustained productivity and agronomic potential of perennial rice
a, Rhizome number (plant−1). b, Rhizome length (cm). c, Pollen fertility (%). d, Plant height (cm). e, Tiller number (plant−1). f, Grain number (plant−1). g, seed setting rate (%). h, Panicle length (cm). i, Grain weight (mg). P1, O. sativa RD23 as female parent (red). P2, O. longistaminata as male parent (blue). F1–F9 (black). The error bar represents the standard error of each treatment. Data are presented as means, and l.s.d. for the traits are: a) 4; b) 9.6; c) 2.4; d) 2; e) 20; f) 2,753; g) 7.6; h) 3.0; and i) 1.0 (N = 33; P < 0.05) (see Supplementary Table 1).
