The Chi-square (χ 2) goodness-of-fit test ratios of leaf color segregation in BC and F2 populations
| Populations | Total plants number | Number of purple leaf individuals* | Number of white leaf individuals | Expected ratio | χ 2a |
|---|---|---|---|---|---|
| F1 | 16 | 16 | 0 | - | - |
| F2 | 1008 | 750 | 258 | 3:1 | 0.19 |
| BC1P1 | 2034 | 1040 | 994 | 1:1 | 0.52 |
| BC1P2 | 200 | 200 | 0 | - | - |
*Purple plants and white plants were determined by visual inspection
a χ 2 > χ2 0.05 = 3.84 was considered significant
