project update by
Just posted the same update on the OSSI forum.
Kholodok has a typical oval shape for mid late Russian watermelons and you can keep it till New Year party (3-5 months). Usual weight is 7-30 kg, no overripe and the taste is improving after 1 month of storage.
I decided to try finally opening my "Christmas Watermelon" for this year. It was soft but only had a brix of 4% (an improvement over 2%). I actually think it was under-ripe, so maybe i should aim for breeding a New Years watermelon instead of a christmas watermelon? Except it was fairly soft, so it probably was not overripe. Still, it is a fun project. ;D The "go" gene for yellow/gold rind ripening would come in VERY handy for this project.
Does someone want to try crossing these seeds with an improved gold-skin watermelon?
If anyone is interested in this sub-project for winter storage watermelons, I would be willing to share some of the limited seed with anyone who would like to try crossing it with the Russian Kholodok watermelon variety which is already reported as a winter watermelon variety.
