Lot of info (and photos) there, for example let see Lemonade Citrus which was topic recently:

"
'Lemonade' is a hybrid variety originating in New Zealand. It is a cross of lemon and grapefruit. This vigorous and high shrub starts producing fruit really soon and is very sensitive to frost. Fruit's rind is usually plain yellow, thick and easy to peel, whereas the pulp is very juicy, sweet, distinctive, refreshing and contains 10-15 seeds. The fruit's juice can be used as lemonade.

Poncirus Trifolita and its hybrids are separated here:

Thanks for the links. I tried growing lemonade last year from seeds I bought on eBay but none of them sprouted, and now I can't find the seed anywhere. This was before I discovered the baggie method, I bet that would of worked.

Ivica, did you convert the citrus page from Czech Republic over to English, or are the forums opperated in English? - Millet (876-)

Millet,

Those pages have english version as option. Two flags (CS, EN) for language selection should be visible on the right-up window corner.
However, english content should be supplied by contributor and if it is not then default language page is given.

Forum in general, their message:
"There are no translations available at this moment, but we are working on it."

Just found mention of our member there,

"Actinidia kolomikta fruit contains more C vitamin than arguta fruit and the highest levels of vitamin C are in the fruit from Mr. Kola, Nr.17"
In Czech version, Mr. Kola becames p. Koly.
"Koly" is typo I guess.
Jan Kola is member of our forum,

Clicking button "Actinidie kolomikta '17'":
English:
http://www.exotickerostliny.cz/en/katalog-rostlin-othermenu-95/kiwi-othermenu-87/66-aktinidia-kolomikta.html
"'17' was bred by Mr. Kola and it produces big, 4,5cm long, green, delicious fruit that ripens by in the second half of July. This cultivar is not self-pollinating."

Czech:
"Odrůda vyšlechtěná panem Kolou, plody 4,5 centimetru, zelené, dobré chuti, úrodná, není samosprašná. Dozrává koncem července."

Google translation:
"Variety bred by Mr. Round, 4.5 inch fruits, green, good taste and fertile, it is not self-fertile. Ripens in late July."

Putting aside what happens with name (Kola -> Kolou -> Round),
centimeters are translated as inches, amasing.

Hello Millet,

I know Zdenek Cernoch (and family) personally and have already been in his home near Ostrava (Czech Republic) in August 2009. He is really a citrus professional and showed his nursery to my friend Markus and me.

The business contact with foreign countries is managed in English by his sister Radka, who lives in the US.

Whoever needs to get in touch with him could drop me a PN or mail

Kind regards,
Norbert
