Extended Data Fig. 9: Effects of knocking out OsLRR2 in variety XS11 on rice yield parameters in the field in 2021 and 2024.
a) Growth phenotypes of ko-lrr2 lines and wild-type (WT) plants at maturity in the field. Bars, 10 cm. b−e) The grain yield per plant (b), number of panicles per plant (c), seed setting rate (d) and 1,000-grain weight (e) of ko-lrr2 and WT lines in the pest-controlled field in Changxing, Zhejiang in 2021 and in Sanya, Hainan in 2024. Data in (b−e) are presented as mean values + s.e.m., n = 3 individual plots, each plot collected from 5 hill plants. f,g) The 10-grain length (f) and 10-grain width (g) of ko-lrr2 and WT lines in the pest-controlled field in Changxing, Zhejiang in 2021 and in Sanya, Hainan in 2024. Data in (f,g) are presented as mean values + s.e.m., n = 15 biological replicates. h) Mature grain of ko-lrr2 and WT rice plants in the field. Bars, 1 cm. Asterisks in (b,c,e−g) indicate significant differences in ko-lrr2 lines compared with WT plants evaluated by Bayesian analysis of variance (**P < 0.01 and ***P < 0.001). For P values, see source data.
