T₁B₁表示叶长(从T₁到B₁之间的距离, 其它长度性状以同样的方法描述); T₁M₁表示顶裂片长; T₂B₂表示左上叶脉长; T₄B₄表示左下叶脉长; T₃B₃表示右上叶脉长; T₅B₅表示右下叶脉长; T₂M₂表示左上裂片长; T₄M₄表示左下裂片长; T₃M₃表示右上裂片长; T₅M₅表示右下裂片长。叶宽和叶片最宽处所在位置的测量方法如图所示, 其它的宽度性状以同样的方法描述, 包括顶裂片宽、左上裂片宽、左下裂片宽、右上裂片宽、右下裂片宽。α₁和α₂分别代表左上叶脉角度和右上叶脉角度, β₁和β₂分别代表左下叶脉角度和右下叶脉角度。叶柄长的测量方法如图所示。Bar=1 cm

Figure 1. Schematic diagram of quantitative trait measurement for the leaves of large-flowered Chinese chrysanthemum cultivars
T₁B₁ indicates leaf blade length (the distance from T₁ to B₁, other length traits are described in the same way); T₁M₁ indicates top leaf lobe length; T₂B₂ indicates leaf vein length of left upper lobe; T₄B₄ indicates leaf vein length of left lower lobe; T₃B₃ indicates leaf vein length of right upper lobe; T₅B₅ indicates leaf vein length of right lower lobe; T₂M₂ indicates left upper leaf lobe length; T₄M₄ indicates left lower leaf lobe length; T₃M₃ indicates right upper leaf lobe length; T₅M₅ indicates right lower leaf lobe length. The measurement method of the leaf blade width and the widest part length is shown in the figure; other width traits are described in the same way, including top leaf lobe width, left upper leaf lobe width, left lower leaf lobe width, right upper leaf lobe width, right lower leaf lobe width. α₁ and α₂ indicate angle of leaf vein in the left upper lobe and the right upper lobe, respectively, β₁ and β₂ indicate angle of leaf vein in the left lower lobe, and the right lower lobe, respectively. The measurement method of leaf petiole length is shown in figure. Bar=1 cm
