Segregation of morphological traits in the barley F2 population. The morphological markers are designated following the nomenclature for barley genes described by Francowiak [23].
| Trait | Gene | Dominant | Recessive | N | χ2 3:1 | p | χ2 9:7 | p |

| Number of rows | Vrs1 | 230 | 73 | 303 | 0.13 | n.s. | ||
| Type of awn | Kap | 169 | 133 | 302 | 58.39 | *** | 0.01 | n.s. |
| Length of awn | Lks2 | 56 | 77 | 133 | 76.75 | *** | ||
| Type of grain | Nud | 237 | 65 | 302 | 1.95 | n.s. | ||
| Leaf variegation | Wst | 237 | 66 | 303 | 1.67 | n.s. | ||
| Stem pubescence | Hsh | 186 | 70 | 256 | 0.75 | n.s. |
***: p < 0.001, n.s. (non-significant): p > 0.05, N: total number of individuals. The specific phenotypes (dominant and recessive) for each trait are indicated in the Materials and Methods section.
