Hi.
Anyone know of the use of punnett diagrams in Epi hybrid breeding?

or http://kippenjungle.nl/sellers...

These are two links which relate to poultry but the concept is valid generally.

For example we could select phylloclade type as a trait and make a start there.

Have come across some tuition on Punnett diagrams, they refer to them as Punnett squares.

May be of interest to others as well as my self. At least it is a starting point.

Using a Punnett diagram how would one express the difference in the two photos for American Sweetheart in the Plant Data Base?




There are/were other photos on the Net which show other characteristics for the hybrid.

There are/were other photos on the Net which show other characteristics for the hybrid.

Been a bit concerned about the difference noticed. Further seemed to recall some mention of a genotype producing a different phenotype under differing environmental conditions.

Did a search this morning which makes that point:
https://socratic.org/questions...
also from https://en.wikipedia.org/wiki/...

Genotype is one of three factors that determine phenotype, along with inherited epigenetic factors and non-inherited environmental factors. Not all organisms with the same genotype look or act the same way because appearance and behavior are modified by environmental and growing conditions. Likewise, not all organisms that look alike necessarily have the same genotype.

Life, a learning experience.

Someone way in front with their interests!

beckygardener said:Y'all have posted some things to ponder. I guess the only way to know for sure would be to do a genetic test on the parents and the seedlings to verify parentage. (Not going to happen, btw.)

I did create a Pedigree Chart for this "possible" cross:



I wish I could fill in ALL the photos to see if any of those unpictured seedlings might resemble my children.

I don't know.... anyone care to comment further after looking at the pedigree chart?

Cheers.

Some historical background. Notice Padre is mentioned so it's been around for quite some time.

After much searching in earlier years, have finally found how the Yellow flowering Epi's were developed.

From: http://epiphyllums.blogspot.co...
A yellow blossom was not bred until the late 1950s when Southern California hybridizers Paul Fort and Garland O'Barr produced the epiphyllum "Reward", a nine-inch flower with chrome yellow back petals and pale yellow to white inner petals. It was one of three yellow-flowering plants produced from a cross of two white hybrids, one of which had a slight golden cast. Today there are a number of beautiful yellow epi's; however, a blue one still eludes hybridizers.

According to Matts http://www.mattslandscape.com/..., REWARD is a cross of 'Thorinne' x 'Madonna'.

Have just found a most interesting book "Epiphyllum Handbook By Scott E. Haselton". It is available as a download, in various formats, at https://archive.org/details/Ep...

Cheers

Have received permission to post the article shown in the photo's from Bill Hildyard bcss@.... on this thread.

I found it interesting, hope you do.

Have re-arranged the viewing order following completion of viewing all videos. Not perfect, if you have a suggestion on how it could be improved, please post a reply.

Have been looking some more into Polyploidy mainly because I've done a few pollinations between genera and ploidy levels.

Recently came across the site, Aberrant euploidy and An Introduction to Genetic Analysis. 7th edition. which others may find interesting as well.

Cheers

Came across an interesting site today, unfortunately in German.

Tried Google translate and found it now(?) enables you to translate as you explore the site.

Rather than open new pages in the existing page, tell the link to open in a new tab.

Marvellous. German Hybrid Forum
