Predicted genetic effects with significance and heritability of boll number for cotton regional trials in three locations and three years.

Note:a = additive effect; ae3y1, ae3y3, aae3y1, aae3y2, aae3y3 as defined in Table 2; ae3y2 = additive by environment interaction effect at Nanjing in 2008, aae1y1 = epistasis by environment interaction effect at Anyang in 2007, aae1y2 = epistasis by environment interaction effect at Anyang in 2008, aae1y3 = epistasis by environment interaction effect at Anyang in 2009; −Log10P = minus log10 (P-value),h2 (%) = heritability (%).
