Construction of an ultradense genetic map and a consensus genetic map To guarantee a set of high-quality SNP markers, SNPs with a depth in the parents < 10 × , SNPs with an integrity ≤ 70%, and highly significant SNPs with SD ( P < 0.01) were filtered out.
Correlation analysis revealed significant or extremely significant positive correlations between leaf width (LW) and leaf length (LL), leaf index (LI) and LL, fruit longitude (FL) and LL, FI and LL, and LI and FI ( P < 0.05) and between single-fruit weight (FW) and FL, FW and FD, and FI and FL ( P < 0.01), respectively, whereas a significant or extremely negative correlation was observed between pairs LI and LW and LI and FD ( P < 0.05) and between FI and FD ( P < 0.01), respectively (Fig. 2 A-C).
