Figure 1

The seed germination of two parents and their recombinant inbred lines (RILs) at normal (28 °C) and low (15 °C) temperatures. (A). The germination phenotype of the two parents, Lijiangxintuanheigu (LTH) and Shennong265 (SN265), as well as the four RIL lines incubated for 3 days at 28 °C and for 6 days at 15 °C. R136 and R145 have 11 positive QTLs, whereas R77 and R144 have no positive QTLs. The bars = 5 mm; (B). The germination behavior of LTH (black) and SN265 (red) under low temperatures at 15 °C. The means are shown in triplicate; (C–F). The frequency distribution of low-temperature germinability in the RILs incubated for 5 days (C), 6 days (D), 7 days (E), and 8 days (F). Arrowheads indicate LTH or SN265.
