x Amarygia leaves

Hi Alan,

This topic has been well covered by people from this forum and I have a
supplementary view about the breaks in leaf colour found in most F1
Amarygias. There is little doubt in my mind about virus infection in the
clumps of XAmarygia Parkerii in the Adelaide Botanical gardens labeled
XAmarygia Parkerii. However having collected, bought and swapped F1
Amarygia bulbs from 9 different sources across 4 Australian states - it is
clear that I have 3 cultivars that are totally free of the leaf colour
breaks. The past two winter seasons have been very favourable (extra ground
moisture) for XAmaygia growth and consequently all but 2 of the Amarygias
in my collection show no sign of leaf color breaks this season, just clean
even coloured bluish/ green leaves.
Two cultivars with larger bulbs and wide ground hugging leaves are the only
cultivars to retain and perhaps even more strongly express the light green
(almost yellow) /darker green streaking of all the leaves. Five of the
other seven xAmarygias are clear this season but in other seasons display
small sections of disruption of the leaf colour light green/blue green.

Having discussed this with a visiting botanist examining my garden bulb
collection we came to the conclusion that in most F1 xAmarygias there was an
incomplete expression of leaf colour in the cross between B. josephinea
(glaucous leaf) x Amaryllis belladonna (light green leaf). This seems to
be a reasonable conclusion as the leaf colour breaks are not found in
cultivars of Amaryllis belladonna nor from the backcrossed cultivars of
Amaryllis belladonna x F1 xAmarygia - but are found in almost all F1
xAmarygia's. Those cultivars showing yellow streaks covering most of the
leaf surface are without question infected with a virus.
