Large- and very openflowered progeny were developed.

H. leopoii

H. pardinum

Vittatum group

The majority originated in France, England.

H. vittatum

Riticulatum group
Were generally smaller in stature than other hybrids, evergreen, and featured a white or yellowish stripe down the midrib of the leaf H. riticulatun var. striatifolium
H. riticulatun var. striatifolium 10

American: the late nineteenth to early twentieth centuries (Reginae, Leopodii)
– Faded due to disease, competition, and failures in quality control, much of this germplasm was lost.

Europe: declined—the two world wars

11

Netherland—today is the center of modern amaryllis production and breeding.

South Africa has also become an important breeding center and exporter of amaryllis.

Hadeco group (Barnhoorn, 1991)
13

The breeding objectives
1.Flower form (trumpet or long -tubed perianth, novel pigmentation patterns) (yellow, blue and purple system) 2.Reintroduction of fragrance 3.Evergreen foliage 4.Repeat bloom 5.More strictly cultural criteria (resistance to hippeastrum mosaic virus and red scorch) 6.Tolerant cold temperature

14

breeding and ploidy level
The majority of Hippeastrum species are diploid, with a somatic chromosome number of 2n=22.

Virtually all the complex hybrid materials presently in cultivation are tetraploid.

a few species of Hippeastrum have been reported with higher ploidy levels than 4n.

15

The concertration of recent commerical breeding efforts among the various populations of tetraploids may exist for several reason:
1.Desirable characteristics of flower size, scape number, and plant vigor are already stabilize in the hybrid races.

2.Sterile triploid progeny result when diploid species are crossed with tetraploid hybrids.

3.Many of the diploid species are not readily available.

4.self-incompatibility, which occurs in most diploid species and diploid hybrids, generally breaks down in the tetraploid hybrid.
