  1. Positions of trait associated polymorphisms are presented according to public reference sequences.
  2. LD linkage group in a linkage block; 1 the LD group contains 17 polymorphisms in complete LD in PAL and 947 and 1655 are the first and last polymorphisms; 2 the LD group contains two polymorphisms which are in complete LD; 3 the LD group contains three polymorphisms with r2 > 0.89. Associations identified by GLM were after controlling multiple testing, while those identified by MLM were not. Polymorphism positions are denoted by the position in our alignment; R2% is the proportion of phenotypic variance explained by the detected polymorphisms/LD group; * and ** mean P < 0.05 and P < 0.01, respectively.
  3. 4CL: 4-coumarate:CoA ligase, C3H: p-coumarate 3-hydroxylase, C4H: cinnamate 4-hydroxylase, CAD: cinnamyl alcohol dehydrogenase, CCoAOMT: caffeoyl-CoA O-methyltransferase, COMT: caffeic acid O-methyltransferase, F5H: ferulate 5-hydroxylase; PHT: plant height in cm; DTS: days from sowing to silking; DMC: % dry matter content of stover; DMY: dry matter yield of stover in tons per hectare
