Path diagram showing the direct effect of the 11 explanatory variables on seed cotton yield assessed for parents and F1 crosses across the 2019 and 2020 growing seasons. Bidirectional arrows show the correlation between the variables, and unidirectional arrows indicate a direct effect on the direction of the arrow. Green and red arrows represent positive and negative effects, respectively. The color intensity and width of the arrows represent the standardized path coefficients values. Solid arrows indicate P ≤ 0.05 and dashed arrows indicate P > 0.05. LCY, lint cotton yield per plant; SCY, seed cotton yield per plant; SI, seed index; BW, boll weight; NBP, number of bolls per plant; LP, lint percentage; LI, lint index; NSB, number of seeds per boll; MIC, micronaire; FS, fiber strength; FL, fiber length; FUR, fiber uniformity ratio
