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. Abbreviations in ANOVA source: G, ramie genotype; Y, data collection year; GP, ramie growth period within 1 year with GP1 (from April to July) and GP2 (from August to December) (i.e., plant harvested at the end of July). Different capital letters within each measured trait indicate significant differences at the p < 0.05 level between the trait measured in 2010 November and 2018 November. Different small letters within each measured trait indicate significant differences at the p < 0.05 level between the trait measured in 2018 July and 2018 November.
