Figure 1
Seed germination of the diverse maize panel under chilling conditions. Germination was defined as root emergence from seed. The chilling condition was set to a temperature of 8 °C. Root emergence was observed daily for 31 days. Germination rates were calculated on the 21st day for all 241 inbred lines. Above, these inbred lines are sorted based on their germination rates, from high (left) to low (right). Several of the line names are displayed across the horizontal axis. Six lines are selected (red arrows) to demonstrate their degree of root emergence with pictures.
