EFB, number of effective first branches; SP, number of siliques per plant; SS, number of seeds per siliques; PY, seed yield per plant; BY, block yield; TSW, seed weight (n = 1000); **, P < 0.01; *, P < 0.05

^a The numbers above the diagonal are genetic correlation coefficients, and the numbers below the diagonal are phenotypic correlation coefficients.
