In spring of 2012 I pollinated several dozens of flowers of Citrumelo 5star with pollen of the clone of C.Ichangensis from Baches nursery.
This clone is supposed to be the most winter hardy, it has white flowers but fruits are dry inside.
I got several hundreds seeds and selected approximately a hundred seedlings that looked like zygotic ones.
They were planted in a ground in spring of 2013. Protected by frost blanket only for the first winter.
At the moment 15 seedlings are still alive and 2 most resistant (no damage during all this time) flowered and gave fruits this year.
Ichangstar 123260
Ichangstar 123261
Fruits of 123260 started to turn yellow in the beginning of October
while 123261 is lagging behind by approximately two weeks

Yesterday I harvested the first fruit of 123260. It weighted 67 grams, rather thick albedo, many seeds but still one teaspoon of juice.
External skin has a pleasant floral smell with pine note.
Albedo initially seems not very bitter but gives a strong bitterness after while. Juice has a very pleasant grapefruit like smell, it is acid, but less than lemon juice, rather high sugar content (13° Brix°) No internal oils common in poncirus and many of its hybrids, no poncirus smell or aftertaste.
I believe that this hybrid is more resistant than N1triVoss and even 5star Citrumelo, it has never lost leaves during these period, with some winter nights of -11C, strong winds, snow and several episodes with soil frozen for two weeks.

Fascinating experiment! I’m curious whether #123261 will be like #123260 (the flowers looks quite different already).
Do you have a special numbering scheme, or does 123260 mean that you’ve already tracked more than a hundred thousand seedlings?

. Do you have a special numbering scheme, or does 123260 mean that you’ve already tracked more than a hundred thousand seedlings? 12 means 2012- year of pollination, 32- code for this combination made this year, 60- in reality 060- a seedling number ( I have a technical possibility to germinate around 1000-2000 seeds each year). |

Great job. When are you starting to sell your seeds. Please let me know. One of my in-law live in snowy area and she wants to Citrus tree in her yard. |

Congratulations Ilya, do the seeds appear to be polyembryonic? I know it may not be detectable if the seed coat is thick.Seeds would be of interest, if you have adequate numbers in the future.

How do you, tell which seeds are Zygotic?
Perhaps you will re-create an Ichang Lemon with added Poncirus cold tolerance?
Always interesting. Nice Job Ilya!

How do you, tell which seeds are Zygotic? After initial growth I select zygotic seedlings by appearance and taste of their leaves. |

These plants look good. Congratulations! Most of the cross-pollinations I have made in recent years are Poncirus hybrids x Ichang Papeda. It will be a few more years before the first fruit comes. Encouraging to see that there can be good fruit qualities.

Ilya send me budwood from his Ichangstar 60 last year, I grafted it onto poncirus rootstock and it has first flowers right now, so far this new hybrid grows vigorously without any problems, so I am hoping to try first fruits this year... good job! That is pretty fast flowering! I lost mine on a bad rootstock from Spain. I`ve got a second chance last season so maybe next year. |
