Temperature responses of germination of control (a) and primed (b) seeds of 89 recombinant inbred lines (RILs) at 27–35°C. Two replicates of 25 seeds each were tested at each temperature on a gradient table, and radicle emergence was scored 48 h after planting. In both panels, RILs are ranked in order of increasing germination percentage of the primed seeds at the maximum temperature at which germination occurred
