*3.6. Analysis of Correlation Matrix*

The phenotypic correlation analysis is being used to explore a linear relationship between various traits, which was visualized in the correlation matrix (Figure 3). In this analysis, DFF displayed a significant positive correlation with FL, while NDVI was correlated negatively. FW exhibited a strong negative correlation with TF and TF showed a negative correlation with YPP. FW and PH showed a moderate positive significant correlation with YPP (Figure 3).

**Figure 3.** Correlation matrix, scatter plot and phenotypic frequency distribution of traits; \* *p* <= 0.05; \*\* *p* <= 0.01; \*\*\* *p* > 0.001; DFF = Days to first flowering (day), FD = Fruit diameter (cm), FL = Fruit length (cm), FW = Fruit weight (g), YPP =Yield Plant−<sup>1</sup> (kg), NDVI = Normalized difference vegetation index, PH = Plant height (cm), SLA = Single leaf area (cm2), SPAD = Soil plant analyses development, TF = Total number of fruits.
