Soybean Oil-Quality Variants Identified by Large-Scale Mutagenesis
Figure 2
Reproducibility for fatty acid levels in selected mutant lines. For each M3-M4 pair the open circle on the left represents the fatty acid level observed in the M3 seeds, and the black diamonds represent the levels observed in the M4 seeds descended from M3 individuals. Key for the labeling of each line is found in Table 1. The dotted horizontal bars on each plot represent the mean level of the fatty acid in wild-type Williams-82 (W82) seed samples. Actual values for a representative W82 sample (as well as values for single plant progeny from this W82 plant) is plotted on the far right of each plot for reference. Level of significance was calculated by Welch’s t-test comparing values from M4 samples to these ten wild type seed samples. , , , NS: not significant. (a) Palmitic acid mutants (mean palmitic acid for W82 = 10.6%), (b) stearic acid mutants (mean stearic acid for W82 = 3.9%), (c) oleic acid mutants (mean oleic acid for W82 = 23.2%), (d) linoleic acid mutants (mean linoleic acid for W82 = 54.8%), and (e) linolenic acid mutants (mean linolenic acid for W82 = 7.7%).
