Table 2.
Tests of fixed effects for three genotype classes of LcyE in 5 and CrtRB1 in 15 mono-genic segregating populations and their 9 interaction classes in 6 digenic segregating populations for LUT, ZEA, BCX, BC, ProA, and Ratio
| Effect | df | LUT | ZEA | BCX | BC | ProA | Ratio |
|---|---|---|---|---|---|---|---|
| F val | F val | F val | F val | F val | F val | ||
| LcyE genotype | 12 | 1.92 | 0.05 | 0.03 | 0.00 | 0.01 | 0.78 |
| CrtRB1 genotype | 42 | 1.25 | 7.73* | 0.39 | 18.71** | 13.59** | 1.01 |
| CrtRB1 and LcyE interaction | 72 | 7.51** | 11.17** | 18.93** | 20.97** | 16.48** | 12.20** |
This is not an ANOVA table; each row in this table is extracted from ANOVA for different sets of data/populations
ProA = BC + (0.5 × BCX)
Ratio = LUT/(ZEA + BCX + BC)
F value followed by *, ** or no symbol indicates significance at P < 0.01, P < 0.001, and not significant, respectively
LUT Lutein, ZEA zeaxanthin, BCX betacryptopxanthin, BC beta-carotene, ProA total provitamin A carotenoids, Ratio ratio of α- to β-branch carotenoids
