  1. Env., two testing locations (E1, Handan, E2, Cangzhou) in 2015 and 2016. Mean referred to the mean value ± standard deviation. CV%, coefficient of variation. Data without underline were from the recombinant inbred line (RIL-P) and backcross (BC/P) populations in paternal BC trials; *: Data with BOLD TYPE were from the RIL-M and BC/M populations in maternal BC trials
