Heatmap and hierarchical clustering divide the growth regulators (T) and CMS lines (L) into different clusters based on floral, growth, and yield-related traits. Blue and red colors indicate low and high values for the corresponding trait, respectively. DSO: duration of spikelet opening, SOA: spikelet opening angle, SL: style length, FLA: flag leaf angle, TSL: total stigma length, SB: stigma brush, SW: stigma width, PH: plant height, PL: panicle length, PE: panicle exertion, NFPH: number of fertile panicles per hill, PW: panicle weight, SS: seed set, GY: grain yield, and HI: harvest index.
