Clivia Yellows

from Shields Gardens

Genetics of yellow and peach flowers in Clivia miniata and its hybrids. Based partly on discussions in the clivia-enthusiast list on Yahoo Groups.

There are at least three genetic types of yellow Clivia miniata: Group 1; Group 2; and Non-1, Non-2. The latter group, Non-1 Non-2, is not well know so far. There may be several different genetic groups in the Non-1 Non-2 category.

Some of the following classifications are well established, but many -- especially some of the Group 2 classifications -- are tentative at present.

Group 1 Yellows are characterized by yellow flowers with no red, orange, or pink pigment. When a group 1 yellow is crossed with another group 1 yellow, all the offspring have yellow flowers when they bloom.

Group 2 Yellows are characterized by yellow flowers which may also show some light red, orange, or pink markings when wounded or rain-spattered. When a group 2 yellow is crossed with another group 2 yellow, all the offspring have yellow flowers when they bloom.

When any group 1 yellow is crossed with any group 2 yellow, all the seedlings from this cross will have pigmented flowers, orange, pink, apricot, or rose in color.

Both group 1 and group 2 can also have peach colored flowers. When a group 1 peach is crossed with a group 1 yellow, the offspring are all peach in color. Similarly, when a group 2 peach is crossed with a group 2 yellow, the offspring are also peach in color. In such cases, the offspring are said to be "split for yellow." That is, at the group 2 gene locus, one chromosome carries a peach gene and the other chromosome of the pair carries the yellow gene.

An interesting side note is that the gene(s) controlling leaf width seem to be located on the same chromosome as the group 1 color gene.

I'm indebted to Mick Dower, Cape Town, for providing much of the information in this page. Thanks, Mick!
