Pearson’s correlation between eleven early maturity related traits. DFF: Days to first flower, DFBO: Days to first boll opening, PCH-1: Percent crop harvest at the first pick, PCH-2: Percent crop harvest at the first two picks, BI: Bartlett’s index, HFFB: Height of the first fruiting branch, NNFFB: Node number of the first fruiting branch, MMD: Mean maturity date, EP: Earliness percentage, PRI: Production rate index, PCH-L: Percent crop harvest at the last pick, *: P < 0.05, **: P < 0.01, ***: P < 0.001, ns: P ≥ 0.05
