Figure 5.

Illustration of the pod fiber content in stringless and stringy common bean varieties. Dorsal (left) and ventral (right) sheats of pods of stringy type Wagenaar (8 in the Figure), stringless type Fijne tros (2 and 3 in the Figure), intermediate F1 plants obtained after the cross between Wagenaar and Fijine tros (4, 5, and 6 in the Figure), and young pods of variety Fjine tros (1 in the Figure). The Figure shows the distribution of parenchymatic (i.e., non lignified), wood (i.e., lignified but not thickened), and fiber (i.e., lignified and heavily thickened) cells. The percentage of fiber and wood cells is shown for each pod type below the corresponding drawns (from Prakken [26]).
