Cold Hardy Citrus / Re: F2 citrange winter hardiness trial
« on: April 19, 2023, 08:49:25 PM »
Good luck!  Sounds like a good cross.

I thought my Bishop citandarin was dead.  But yesterday I saw two tiny green leaves.  Impressive here in central Kansas.  Zone 6.  Trunk and branches don't look good.  It might still die.  But still impressive.

Cold Hardy Citrus / Re: Hardy citrus in PNW
« on: April 01, 2023, 02:32:48 AM »
I commented some time ago that an F1 hybrid of finger lime x Ponciris+ might have a market.  I've been thinking more about it lately.

interesting you bring up Mendel, modern statistics shows he almost certainly fabricated his data to make dna appear more linear and less random! I think his heart was in the right place but still, bet he never expected that
 


One of my genetics professors pointed out that Mendel lived before modern statistical methods ere in use.  My prof thought Mendel kept counting until the numbers ere close enough that he noticed a pattern and then stopped.  That ould have been quite acceptable in his day.  And it is not the same as fabricating.  It as state of the art at the time. 
Today no one should judge the man or his motives.  And his discovery asn't recognized  until it as rediscovered by 2 more modern geneticists ho did a litterature search after discovering the same ratios in corn.  So Mendel's one publication had no influence on the science of genetics.

I do what Millet and Poncirisguy said.  If I need to mow or do garden work I do that while a pot is soaking.  Or reading a good book works too.

Akebia is right.  Working for zone 6 hardiness will have spinoffs for zone 7.

I was thinking about that cross Till.  It doesn't fit in with my breeding plans or goals.  But it would certainly interest me.

Good information.  Thank you.

Cold Hardy Citrus / Re: Tetraploid Citranges
« on: December 29, 2022, 04:21:29 PM »
I did grad work in genetics but I was studying vegetables and grain so this might not appply to citrus.  If anyone does know the effects of tetraploidy in citrus, listen to them, not me.
In vegetables, a few species have more vitamin  C in the tetraploid than the diploid.  But generally the difference is small or none at all.
In grains, wheat, rye and barley, tetraploids tend to be slightly less cold hardy than the same variety at the diploid level.  That is for rye (Secale cereali), barley (Horeun sativa) which are normally diploid.  Wheat (Triticum species) has diploid, tetraploid, and hexaploid species.  In Triticum, we can't directly compare diploid vs higher ploidy because there has been centuries of selection for different climates so the genetics is much more important than ploidy.

So I expect the difference between diploid and tetraploid citranges to be small.  But there are a few plant families that don't follow the general rules.  So it is possible citrus don't follow these general rules.

Citrus General Discussion / Re: Turunji - A Citrus You Eat Like An Apple
« on: December 28, 2022, 10:19:12 AM »
Sounds like Turunji is a bit harder than some citrus on their own roots.  Or perhaps they are too often pot bound by those that sell them.  I am in the process of loosing mine I bought from Logees.  I think I'll try to save it by grafting in some extra roots using Ponciris seedlings.  Mr. Hong in Wichita KS gave me 100 Ponciris fruit last fall and they average about 30 seeds per fruit, so I have plenty to spare.  I also have seedlings from the last 2 years, more than I have scions for.
Here is where I got the idea.

I've never heard of it being illegal in the USA. Is there anyone here who keeps up on these things?  It's been 40 years since I was up to date on this.

Cold Hardy Citrus / Making new periclinal chimeras like Prague
« on: November 16, 2022, 02:09:34 PM »
A new way to make periclinal  chimeras in citrus is given here.
日 植 病 報 60: 82-88 (1994)
Ann. Phytopath. Soc. Japan 60: 82-88 (1994)
OK,  1994 isn;t new but it is new to mr,  The procass was developed to give disease resistanc in citrus by giving a good variety a coating of a disease resistant variety,  But it seems to me it might work on making good citrus varioties a coating of a cold tolerant variety like ponciris,  The publication says 1/6 of plants made this way were periclinal chimeras,
One would need to use a good varity of citrus that has nucelar seeds,  No problem finding those,
I don't expect the rresulting plants to be hardy in one 6 where I live,  But maybe zone 7 or 8?  Maybe anywhere PPrague is hardy?

Cold Hardy Citrus / Re: Stingerless bees for pollinations
« on: November 09, 2022, 08:23:25 PM »
Adding wild flower is a good idea.  But the town has been spraying for mosquitos for so many years that bringing in pollinaters is also a good idea,  Preferably native species that might become re established in the area.  An idea I just had istoget a hive and keep it most of the year on a nearby ranch.  Bring it to the orchard (breeding area) during bloom and moving it back for the rest of the year,  But I'd have to check what is being sprayed on the ranch land,  Aerial spraying is a big industry here,

Cold Hardy Citrus / Stingerless bees for pollinations
« on: November 07, 2022, 11:51:05 AM »
As a child and young man I kept bees.  I like them and I like honey.  But my citrus "orchard" is on the edge of town ad bees close to a population of humans seems a bad idea.  I know at least one neighbor who is allergic.  So I'm thinking of buying a start of  native stingerless bees.  I know that some temperate zone fruit orchards are using them with good results.  Are they being used successfully with citrus and other fruits?
And as a breeder who wants masses of crosses, I'd like bees to do some of my work for me.

Cold Hardy Citrus / Re: Poncirus+ x kumquat
« on: November 01, 2022, 10:36:00 AM »
https://tropicalfruitforum.com/index.php?topic=29541.50

Perhaps this was one of the threads that got you interested.  Though these crosses were not with P+, they could be useful.  While I haven't read of test crosses to prove it, it seems like the difference between P+ and other ponciris is a single gene.

Cold Hardy Citrus / Re: Poncirus+ x kumquat
« on: November 01, 2022, 10:11:35 AM »
Its good to have another person working on more winter hardy citrus.  Being in zone 7 I think you will get a bigger percent of survivers than Kumin in zone 6.  If vnomonee's fruit's seedlings do have trifoliate leaves, then that will jumpstart your work.   There was a thread active a while back on crosses of Ponciris and kumquat.  The discussion went that many kumquat x Ponciris hybrid seedlings lacked vigor and died young.  But some were vigorous and grew well.  So don't get discouraged if your success rate is low at first.

So are you going to be offering seeds for sale?

I have also heard of having compost piles in greenhouses for the added CO2.

Cold Hardy Citrus / Re: Sweetest tasting cold hardy citrus

Or if you are willing to grow in a pot and bring iy inside winters, you have some options.

or if you are willing to wait an unknown number of years, there will be some other options for outside, in ground.  We are working on it.  But not today.

I have also received free seeds for my breeding program.  I have given too, but less than I received.  I'll send some when I have them

Cold Hardy Citrus / Re: fusion power vs citrus trees
« on: September 02, 2022, 09:13:48 AM »
And all of this is due to fusion power in the sun.  With a lot of help from the greenhouse effect. 
When I was growing up, temperatures of 100F made the news reports now and then.  People would talk about it for days.  But this summer we had 100+ (40-45C) day after day, week after week.  I got really tired of it.  And the garden suffered from it.  Other places had it much worse, of course.

If the scion dies of cold, replace it with a hardier scion.
