Re: Re: HYB:REB:Daylight Dependent & Independent

Hello Robin

Of course all this IS boring when you start in the business,
and i'm glad you re-explained the plicata loci with it's four alleles. Now that i have understood, i feel good.
If you feel like explaining more, ( and i mean by EXPLAINING really explaining like you just did , giving a normal word each time you introduce a jargon word, ) you'll be loved forever by the allergics to reason like me, who just get suddenly all pricky outside and terribly bored inside when they feel left out of the circle of the knowleged ones....
And don't have any regrets about the philosophy classes, we all would be better off if more would have done it too! 
And agronomy is still an option...isn't it?

Betty and Loci
Believe me I do agree with both of you. Certainly when you cross like traits you will get seedlings with those traits. And crossing rebloomer X rebloomer is the best way to get more rebloomers. And the more trigger responses that can be bred into the group, the more likely we are to get individuals with higher doses that would lead to more rebloom. And an individual that was homozygous for all of the traits would be a very useful parent indeed- with good branching, bud count and form too, of course. We dont want much do we. <vbg>
No way am I pretending to be an expert here. My knowledge is pretty much limited to a semester of genetics in college. On top of that- I am still a hybridizing newbie. Just throwing out some of the things that are going through my head.
Allele is just an unusual word, maybe option would be better. The example that comes to mind is the plicata pattern. We know of at least four options that can be present at the site (loci) of the chromosome which controls that pattern. The dominant Pl which expresses as a self, pl which expresses as the plicata pattern, the pl lu for luminata, and pl a for no anthocyanin produced ie. Glaciata. (sorry I dont know how to type the superscripts into the e-mail) Each of these are interchangeable at that site and all of the different possible combinations can lead to different visual effects. (Betty I know you already know this, I am just trying to give an example)
And even if we had genetic maps of hundreds of rebloomers and were able to use the computer to analyze the data and could identify every possible factor that could come into play, we still would have to guess at what an individual may carry. Even knowing what the parents makeup is only gives you probabilities. Really you would have to map each seedling to know its makeup.
Since probabilities multiply as you are trying to combine more factors, from a practical standpoint, the best way to cope with all of the variables is to grow as many seedlings as you can. It has been very interesting to see the results that Thomas Silvers is getting with the diploids. Reducing the number of variables in half is generating higher numbers of rebloom seedlings.
Not trying to be a bore, but I cant help but want to understand it as best I can in hopes that I can make better choices on parent selection. Even an imperfect understanding may help shorten the path. Besides I really cant help myself I took way to many philosophy classes --- over thinking things comes with the territory-- when maybe I should have been taking something more useful like agronomy : )
