RE:HYB:Plicata Genetics Update


An update on what I've been finding. There definately some SDB and MDB 
where there is plicata "pl" and luminata "plu" alleles on the pumilla 
chromosomes. This means several things. One is that with the right 
combinations we can get the full range of plicata genotypes with SDB 
and MDB. It also means reinterpreting the genotypes. To help with this 
I ended up looking at the diploid MTB (minature tall bearded). From 
this I have concluded that the stripped pattern as seen in Flea 
Circus, Circus Stripes, Autumn Circus etc, are genotype "pla pla plu 
plu"  Using data provided by Mike Sutton I now clasify luminatas as 
being "pl pla plu plu". Fancy plicatas are likely "pl pl pla plu"
 Thus glaciata X zonal will produce striped plicatas. Glaciatas X 
luminatas will produce some luminatas, so hardy pinks can be used to 
increas hardiness of luminatas. The wide zonals "pl plu plu plu" such 
as Clarence. Suky, City Lights etc, crossed with luminatas should 
produce 5/12 luminata, close to half of the offspring. As Clarence is 
very hardy, it would be a good choice. Zonal  X luminata will also 
produce some luminatas.
I have also seen an interaction of plicata genotypes with the 
particular pigments. Thus various anthocyanin pigments will show 
slightly differently. For example, the dotted plicatas. Tea Apron 
which is "pl pl pla pla" has a lot of dotting, yet Purple Pepper is 
heavily dotted. Purple pepper has a much darker violet colour, and 
heavier disribution. This interaction seems to produce even more 
dramatic differences in other genotypes and may be able to change a 
luminata into a broken colour. More research and data is needed. There 
also seems to be at least one yellow pigment that is distributed 
according to the same patterns and pathways as is affecting the 
anthyocanin pigments.
