I say we all order supplies and make this a open group project. Because i am confused on how to do it. I have large fig tree to do it with. Just would like help. |

So when you cross a ga/ga feminized pollen with a ga/ga female select fig cultivar, I expect to get 100% ga/ga synthetic hybrid and 100% of the progeny will be common edible fig! I cannot see how you would get San Pedro and the other type of fig when you are making a synthetic hybrid using ga/ga pollen? |

When those pistillate hermaphrodite fig that produce the occasional viable seed self, you get a genetic copy of ga/ga female as the plant selfed itself. You are not going to get any males, no San Pedro and no Smyrna fig! You get all genetic copies of the mother! So why when you take ga/ga 'feminized' pollen and use it in a cross on a different ga/ga edible fig (not Desert King) and get 1/3, 1/3, 1/3??? It does not make sense! |

So again, although fig has what looks to be a two gene system for sex determination GA/ga system...Looking at the fig phenotypes and what we see, suggests there is some quantitative genetic 'REGULATION' of this two gene system.... |

Again, because we see huge phenotypic differences across fig in terms of flower production and now showing that GA3 can be used to induce male flowers.....This suggests that yeah there are two genes, but their phenotypic 'EXPRESSION' appears to be modified by quantitative genetic mechanisms! Hermaphrodite condition most-likely has some form of quantitative genetic regulation of phenotype expression due to the 'regulation of expression' of those two genes! |

That is why we are seeing so much variation in sex expression in fig and GA3 works making feminized pollen....FIGS ARE ALL HERMIE WITH A GA/ga two gene sex expression that is 'modified' through quantitative genetic regulator genes....There are most-likely 'suites of genes' that regulate the expression of the GA/ga genes resulting in varied phenos.....And this is what we are seeing in fig! |

Those landrace pistillate hermaphrodite (ga/ga) fig are VALUABLE BREEDING TOOLS! Especially now that it looks like GA3 can be used on the breba to get feminized (ga/ga) pollen and make synthetic S1 hybrids of superior female cultivars....Man, you fig breeders have about 15 years of catching to do to catch up to the 'stoner' Cannabis breeders and this 'feminized seed' thing!...:) |

After reading the genetics of fig in that link....it's QUANTITATIVE in nature! QUANTITATIVE GENETICISTS DON'T WORK ON SINGLE GENE TRAITS. IF IT IS 'SINGLE GENE', IT'S NOT QUANTITATIVE! Hey, FIG IS TWO GENE GA/ga, in which the 'phenotypic expression' of the GA/ga sexual phenotype regulated by other unknown genes that modify the GA/ga expression resulting in a wide range of GA/GA, GA/ga and ga/ga phenotypes we see. |

Two gene is QUANTITATIVE THERE FIG BREEDERS! This makes fig a 'COMPLEX BREEDING SYSTEM' and ALL ARE HERMIE, no matter what you have been told prior! All female and all male plants are HERMIES!!! Go get some GA3 and I WILL SHOW YOU!!! Whether they produce male flowers or not or whether some stress like drought, light or GA3 chemical...SO? THEY ARE ALL HERMIES ON THAT BELL CURVE!!! THAT MEANS WITH COMPLEX BREEDING SYSTEM AND THE FACT THERE ARE FIG PISTILLATE HERMAPHRODITES OPENS UP HUGE, NEW BREEDING PROJECTS THAT COULD NEVER BE DONE IF IT WERE NOT FOR THE FACT THAT ALL FIG ARE HERMIES ON THAT HERMIE BELL CURVE!!! I GIVE YOU FIG BREEDERS 10 YEARS TO CATCH UP TO THE 'STONER' CANNABIS BREEDERS....MAN, THEY ARE SHOWING YOU PEOPLE UP! Just friendly 'ribbing' there fig breeders....You can catch up to the stoner Cannabis breeders and do some good stuff using GA3 and get some good results. |

congatom, you are still missing one (at least) piece of the puzzle. In order to produce fruit without the fig wasp, the "female" tree also needs the gene for presistance. |

You not getting the genetics of this persistance. Persistance is sex linked and when you use a male/female system of breeding, the male 'CONFERS' that DNA TO THE PROGENY! IT 'CONFERS' IT TO THE FEMALE PROGENY SO 'P' IS IN THERE!!! IT WILL PASS IN A gaP/gaP feminized pollen onto a gaP/gaP female select cultivar fig. Look at what I am saying and look at the genetics I gave you...Persistance WILL PASS in a gaP/gaP x gaP/gaP synthetic hybrid cross....NEXT! |

When I look at this: Put in the feminized pollen P+....They leave it out in a NORMAL cross and that is fine....THIS IS NOT A NORMAL CROSS....THE POLLEN IS gaP/gaP. There is no gaP/gaP pollen in a pistillate hermie or pure pistillate hermie in fig...Look at the chart...but that is for female x male cross and PERSISTANCE should pass as we have synthetic gaP/gaP viable 'feminized' pollen. Cross Between Persistent Female Tree (P+) and Persistent Caprifig (P+):

According to the above chart, when you add in the FEMINIZED POLLEN gaP/gaP...PERSISTANCE WILL PASS.....AGAIN, THIS IS 'FEMINIZED POLLEN WITH THE GENETICS gaP/gaP and VIABLE! Cross this on to female cultivar gaP/gaP and what do you get? NEXT! |

Again the Japanese are using GA3 BECAUSE IT WORKS IN CREATING S1 fig hybrids! What do you get when you cross gaP+/gaP+ x gaP+/gaP+(feminized viable pollen)? You get gaP+/gaP+ female plants 100% across the board! Look at the genetics I just wrote down...IT IS CORRECT and REALIZE that feminized gaP+/gaP+ pollen is VIABLE! BOY, THAT OPENS LOTS OF S1 HYBRID BREEDING POSSIBLITIES! |
|||||||||||||||||

Just remember on the above chart the pollen is not coming from a male Caprifig BUT A FEMALE COMMON FIG SELECT CULTIVAR PURE PISTILLATE HERMIE THAT IS FORCED INTO CREATING MALE SEX ORGANS WITH gaP+/gaP+ viable pollen...which most landrace fig can make naturally as they are all pistillate hermies pure pistillate hermies that can make feminized viable pollen....Again, if they have a paper on this in Japan, IT WORKS OR THEY WOULD NOT HAVE PUBLISHED! And if it is GA3, I KNOW WHAT THEY ARE DOING AS I AM AN EXPERT ON QUANTITATIVE GENETIC BREEDING SYSTEMS IN HERMAPHRODITE PLANTS...Cannabis, hop and now looks like fig too...:) |

I am using ALL the genetics the fig breeders talk about.. I just say get rid of 'MULE FLOWER'.. that is just WRONG and understand that fig is not Gynodioecious! That is just a BAD TERM TO USE IN FIG!!! FIG ARE HERMIES ACROSS THE BOARD!!! The ONLY REASON the 'Hermaphrodite Bell Curve' has been shifted in common fig is because of intervention! I bet if you look at wild fig populations the breeding system looks exactly like the Hermaphrodite Bell Curve' I showed you prior with the majority of plants being straight up Hermie and pure pistillate hermies and pure staminate hermies as outliers. It is just with selection that the natural 'Hermaphrodite Bell Curve' has been shifted in fig, Cannabis and hop to favor the pistillate hermaphrodites and pure pistillate hermies.... |

Again, I do not see ANYTHING in the genetics of feminized pollen production that would raise red flags and tell me this S1 hybrid breeding using GA3 on fig breba would not work! If they wrote a paper about it in Japan and published it...THE TECHNIQUE PROBABLY WORKS!!! I am JUST FILLING ALL YOU FIG BREEDERS AND 'POTENTIAL' FIG BREEDER IN ABOUT WHAT LOOKS TO BE GOING ON IN FIG USING PUBLISHED INFORMATION ON FIG GENETICS TO BACK ME UP ALONG WITH INFORMATION ON HERMIE AND DIOECIOUS CONDITION IN PLANTS AND HOW THAT RELATES TO QUANTITATIVE GENETIC BREEDING SYSTEMS IN THESE PLANTS! |

The biggest reason why I am confident this will work and persistance will not be an issue is in the landrace natural pistillate hermie fig that produce the occasional viable seed! The offspring IS A NEAR CLONE OF THE MOTHER WITH JUST A LITTLE SOMA CLONAL VARIATION IN THE QUANTITATIVE GENETICS OF THE OFFSPRING. So, you get the same taste, but STRENGTH MAY VARY, YIELD MAY VARY....Things like that...but the amount of variation will vary...:) Some S1 crosses might yield CLONE-LIKE RESULTS!!! It happens in Cannabis! |

The only question I have is: Is the feminized pollen gaP+/gaP+ viable? But given what goes on in landrace fig naturally producing feminized all female seed from all female pollen, my guess is, the Japanese technique works and YOU GOT THE GA3 concentration now people!!! Someone must have that paper and I am just filling you on a few things by giving you some information you clearly know nothing about and connecting some dots for fig breeders...thats all.... |

Again, looking at the genetics of 'FEMINIZED POLLEN' gaP+/gaP+ and VIABLE (most-likely)....MY GOSH...THE FUN THINGS FIG BREEDERS CAN DO WITH THIS INFO!!!! GA3 is a natural plant hormone, by the way, for those who do not know. It can just do some funky things in plants at high concentrations relative to normal concentrations in plant cells. Someone asked about GA3 and root formation...NO...Rooting compounds are Auxins IAA and whatnot and some Cytokinins for cell division I think...go look a bottle of Olivia's rooting gel..... |

Oops, the Caprfig is P and +, but that does not change what I said...P IS EGG LETHAL AND NOT SPERM LETHAL!!! FEMINIZED POLLEN IS VIABLE AND PERSISTENT AND ALL FEMALE!!!! |
|||||||||||||||||

Registered: Posts: 126 |
I showed the genetics as gaP+/gaP+ when it should be gaP/ga+ viable feminized pollen, right? Yeah, looking at the chart above the alleles persistence are P and + and egg lethal, but not sperm lethal...So again feminized pollen (sperm) NOT LETHAL AND WE SHOULD BE OK! |
|||||||||||||||||
|
congatom
Registered: Posts: 126 |
Yeah, so the P allele is egg lethal...the FEMALE CULTIVAR HAS THE P ALLELE AND THOSE EGGS DIE!!! SO??? WHAT DOES THIS HAVE TO DO WITH CHEMICALLY INDUCING 'FEMINIZED' gaP/ga+ pollen WHICH IS NOT LETHAL...OH AND VIABLE??? |
|||||||||||||||||
|
congatom
Registered: Posts: 126 |
The P allele is in the female fig, but those eggs die and it is never passed...SO? What does that have to do with GA3 induction of male flower structures in the pistillate hermie or pure pistillate hermie prized fig landrace cultivar for viable gaP/ga+ feminized pollen for S1 hybrid prooduction? THE P ALLELE IS EGG LETHAL AND NOT SPERM LETHAL...EVEN 'FEMINIZED SPERM' WITH THE P ALLELE...HOW ABOUT THAT?...:) |

So when a gaP/ga+ persistant fig female cultivar is selfed, 25% of the seed die and the in the rest of the seed 2/3 are persistant and 1/3 xx......That is WAY BETTER THAN 1 in 1000 or the space and numbers when using male caprifig! Again, no wonder the Japanese are doing this! |

In an S1 cross, the 2/3 persistant will be a blending of the two choice female landrace cultivars you selected for the cross....You kinda know what you are getting! |

What is also quite interesting is that by germinating these 'assured viable' fig seeds I will know if this is pistillate hermaphrodite or apomixis! If what is going on is pistillate hermaphrodite, I expect only 2/3 of the seed to be persistant. If it is apomixis, 100% should be persistant.....According to the Punnett Square genetics on persistance I read about.....If it is apomixis, 100% clonal looking plants....Pistillate hermie instead I get 2/3 persistant and 1/3 garbage....correct my genetics if you see a problem....I already corrected myself once with the Persistance alleles being P and +...Sorry about that, but I do not think I made any more mistakes....I cannot wait to germinate those fig seeds and see what I get....2/3 persistant or 100%??? I bet it is 2/3...:) |

Still those odds on a selfing are pretty good....2/3 of the plants are near clones of the mother! Same will be true for S1 hybrids using feminized pollen...:) |

Also, looking at the Cross Between Persistent Female Tree (P+) and Persistent Caprifig (P+): only 50% of the offspring are persistant! When you make an S1 cross, 2/3 of the offspring will be persistant! You get a greater degree of persistance in S1 hybrid and inbred line production and you get the blending of the two selected female parents...so you can kinda predict what you are getting in the resulting persistant offspring in the S1.... |

Hard to predict what you are going to get with male plants....Same goes in Cannabis...that's why they are doing all the feminized seed production for the stoners.... |

congatom, I love your passion and enthusiasm. If P is egg lethal, wouldn't apomixis give you 100% Caducous (non persistent) plants? |
|||||||||||||||||

Apomixis gets around sexual gametes and uses regular 2N cells for the offspring and are a diploid clone of the mother...There is no 'true egg', but again, I am no expert on apomixis...I'll tell you that right now...But my guess is since apomixis does not involve an egg cell, the lethal thing may not come into play at all. I cannot comment further than this. However, when I get those seed from Canada....If I get 2/3 persistant fig offspring then I am most-likely correct that ALL FIG are hermies and the genetic system is gaP/ga+ over the hermie bell curve. If I get 50% persistant females, then I suspect this guy in Canada used a persistant caprifig and if its apomixis....100% persistant(???) Again, I have to look at apomixis more carefully, but I don't think it involves an egg, so no egg lethal and all persistant as it is a REAL CLONE of the mother??? So, for me, next step is germinate those fig seeds and see the ratio of persistance. Is it 2 out of 3, 50/50, 100% or 0% (C. caprifig?? Those are like 1 in 1000 right ??)....So, IF this guy in Canda has VIABLE selfed fig seed from landrace....I suspect I will get 2/3 persistant....Anything else...especially 50/50 tells me he used a persistant caprifig and 100% out of my 24 seeds would be most-likely apomixis and think is HIGHLY UNLIKELY! Then I could get all garbage...HE USED A C. caprifig....Or he is selling non-fertile seeds...but he says they are fertile and I believe him...I bet I will get 2/3 persistant female fig that are close to clones of the mother! 1/3 no fruits...garbage..... |

If you don't like it...sorry....When I see errors in science....especially plant science and plant breeding...I will chime in and give you all an education if need be! I am just trying to help you people out as you have ALL THE INFORMATION, but you are not connecting the dots correctly and I'm an expert on hemphrodite plant complex breeding systems and I had chime in....get out the fig breeding 'dark ages' please....and don't take offense...I'm just trying to give you information that you obviously have no clue exists so that you can accelerate you breeding success and not have to worry about "We don't have Davis or LSU any more!" SO WHAT!!! Look at the stoner Cannabis breeders and what they have done using GA3! No excuses people....Giddy up....It is going to be a while before you fig breeders catch up to the stoners...:) Friendly ribbing people...:) I got to go...cheers all...:) |

Here is some 'Old School' info on Cannabis and hermies it relates well to fig too! |

Only problem, Robert Clarke whiffed on the last sentence of the first paragraph and he MEANT TO SAY "Therefore, the difference between 'DIOECIOUS' and hermaphrodism is one of degree determined by genetics and environment.... He is talking about dioecious and hermies and then therefore for the monoecious and that is not correct.....But I know what he meant to say as I AM SAYING IT! Again, ROBERT IS TALKING ABOUT THE HERMIE BELL CURVE!!! When it is ONE OF DEGREE, GENETIC AND ENVIRONMENT....THAT BE QUANTITATIVE! |

However, Roberts Clarks assessment on Cannabis is applicable to fig as fig really all hermies and Robert is even suggesting this when he mentions the 'one of degree' thing......So from there the Cannabis breeders got a hold of the 1972 paper on using GA3 to produce 'feminized' pollen and since males are the BANE of Cannabis growers....Here we are 15 years later with stoners breeding for 'feminized seed' and the Cannabis breeding industry has just taken off....All the while, Japan, looks like they understand what is really going on in fig and that the pure pistillates are either pistillate hermies or pure pistillate hermies and with their knowledge of GA3 (as they discovered it)...most-likely working on a 'hunch' like what I am suggesting to all of you....it looks like the Japanese have worked out feminized pollen production using GA3 in breba fig. To think, this might actually work in fig and we can get S1 hybrids....2/3 persistant too and ALL FEMALE!!! MY GOSH!!! |

One more error on my part, but not a biggie....You get 50% persistent when crossing the persistent caprifig onto a edible female fig, BUT, I LEFT THIS OUT....1/2 of those will be male as you are using a male as one of the parents.....look at heterocaprifig below.....YOU BETTER HOPE YOU HAVE A HETERO TOO!!!! So IF you have a hetero caprifig and you cross onto a female edible fig, YOU GET A LOT FEWER PERSISTENT FEMALES AS YOU HAVE MALES TO DEAL WITH ALONG WITH PERSISTENCE. WHEN YOU USE 'FEMINIZED' POLLEN, YOU GET ALL FEMALE AND YOU JUST NEED TO DEAL WITH PERSISTENCE AND 25% gaP/gaP eggs never make it...THAT IS WAY BETTER THAN USING A CAPRIFIG AND YOU BETTER HOPE WHEN YOU USE A CAPRIFIG IT IS HETERO! NO WONDER THE JAPANESE ARE USING GA3 and going the synthetic hybrid route using 'feminized' pollen.....using caprifig males and the NUMBERS SUCK!!!
* = Most likely genotypic combination: Homozygous female tree x heterozygous caprifig. |

I did not show the parent allele column but with the female it ONLY recessive ga.....with the hetero male the bi-alleles are GA and ga....50% males EVEN BEFORE TAKING INTO ACCOUNT PERSISTENCE???

One more error in my Punnet squares.....Not bad though and the comparison favors S1's all the way. When you cross a female persistent fig, you have ga+ alleles in the egg only....all with P alleles die....So when you cross ga+ female gametes with 'feminized' gaP/ga+ pollen, you get 100% female and 50% persistent....That's still way better than using a male for pollen! Half of the offspring will be male BEFORE taking into account persistence and you really do not know how the male contributes to the female pheno just by looking! Again, no wonder the Japanese are using GA3......Sorry for the slight math errors, but it's been a while since I did three gene Punnets and I tend to catch myself when I do simple mistakes like this...:) But still....NO MALES AND 50% persistent......and you know what you are getting.....my gosh! |
