Plant Material
Thirteen Teff lines that were found among white Teff plot were analyzed. These randomly distributed plants looked different from the general population in terms of lodging (Fig S1). A single panicle was collected from 13 of these plants for further study. These lines were propagated off-season in a greenhouse (Fig S2), and from them 11 lines were selected for further detailed analyses under field conditions. These included (Some are detailed in Table 1): 44A-163-B (pure brown) and 44B-163-W (pure white). The three lines: 53-1, 53-2 and 53-3 were also included, and were found to be a mixed color after a generation of propagation (excluding 53-1 which was already mixed when collected) as detailed in Table 1. Each of the three exhibited a different proportion of brown/white seeds after one cycle of propagation (Table 1), threshed as a bulk, and then separated into white and brown manually. We also harvested two plants separately from the greenhouse pot of 53-2 in order to establish a single plant selection according to lodging resistance score, to create 53-2-1-W and 53-2-2-W. As a control we used one of a commercially grown cultivars in Israel, refereed herein as the ‘white cultivar’.
