WT: wild type; PH: plant height; GWD: grain width; GL: grain length; GWT; 1000 grain weight; GNPP: grain number per plant; SSR: seed setting rate. * and ^ns represent a significant and non-significant difference, respectively. Student’s t-test, p ≤ 0.01. These data are from the individual plant of the T₀ generation and the mean of five independent samples from T₁, T₂, and T₃ generations.
