| Materials | No. of seeds | Em ploidy mean 2n ± CV | Range 2n | CI | |
|---|---|---|---|---|---|
| Lower | Upper | ||||
| 2x nat | 30 | 2.01 ± 0.02 | 1.91–2.06 | 1.97 | 2.05 |

| 6x nat | 734 | 6.07 ± 0.05 | 5.66–6.28 | 5.98 | 6.15 |
nat, natural genotypes; syn, synthetic genotypes; Em, embryo; CI, confidence intervals; 2n, sporophytic ploidy level; CV, coefficient of variation; lower and upper bounds of 95% Confidence Intervals for Means.
