Histogram visualization depicts the frequency distribution of reproductive traits across 40 cotton genotypes under three treatments: T₁ (green), the control condition (100% field capacity); T₂ (orange), moderate drought stress (60% field capacity); and T₃ (purple), severe drought stress (40% field capacity). The traits include (A) flower retention per plant (FR), and (B) number of bolls per plant (NBP). Overlaid smooth lines represent kernel density estimations (KDE), providing a clear visualization of the probability distribution of each trait under the three treatments, highlighting the variations and central tendencies across the genotypes.
