MR rates in the progeny (seeds) from reciprocal crosses of heat- (one hour at 32 °C) or cold- (one hour 12 °C) stressed wild type parents (male or female, as indicated by gender symbols) with one of three detector lines: 3154 (top row; a, d); 3158 (middle row; b, e) and 3162 (bottom row; c, f). 22 °C controls for each treatment are also included. Crosses were carried out on wild type parents who were, at the time of pollination, aged 40 days after sowing (DAS; LHS graphs) or 45 DAS (RHS graphs). Numbers at the bottom of each column indicate the number of seeds analyzed. Point predictions and 95% confidence intervals for MR rates are drawn. Solid lines represent any significantly different comparisons within a specific treatment of the 12 °C or 32 °C rates to the 22 °C control (e.g. within dii); dashed lines represent any significantly different comparisons, within a specific treatment, of 12 °C and 32 °C rates (e.g. within dii or eii). The only other type of comparison made was between the rates of the male and female control treatments for a given detector line and parental age (no differences were found). * – P < 0.05; ** – P < 0.01; *** – P < 0.001; no asterisked line – no significant difference. P values are corrected for multiple testing
