BW exhibited highly significant differences among the three environments ( F = 59.83~377.80; p < 0.001), and BW in 2019 Ezhou (5.74 ± 0.41 g) was significantly higher than 2018 Wuhan (4.98 ± 0.34 g) and 2019 Wuhan (4.88 ± 0.36 g).
A total of 79, 110, 50, and 84 DEGs were identified to be around significant and suggested QTNs for BN in the 2018 Wuhan, 2019 Wuhan, 2019 Ezhou, and BLUP datasets, respectively, while 59, 36, 148, and 142 DEGs were identified as being approximately significant and suggested QTNs for BW in the 2018 Wuhan, 2019 Wuhan, 2019 Ezhou, and BLUP datasets, respectively.
