Abbreviations of plant materials: XZ-3, Xiangzhu 3; D-1, Duobeiti 1; XZ-X1, Xiangzhu X1; XZ-X2, Xiangzhu X2; XZ-X3, Xiangzhu X3; XZ-XB, Xiangzhu XB. NFPI of 2010 November was calculated based on the plant height and aboveground yield measured in 2010 November. NFPI of 2018 July and 2018 November was calculated based on the plant height, aboveground yield, and belowground yield measured in 2018 July and November, respectively. NFPI of 2018 average is the mean of NFPI in 2018 July and 2018 November.
