Cold Hardy Citrus / Re: Let's create a new cold-resistant citrus tree!! "Steps and path to take"

3° that the fruit ripens early (before frost). For me, the absence of acidity can make it sweet even if it is unripe, I tried that with C. limetta fruit.
About your problem with FD... the percentage is somewhat "arbitrary", it is statistical. So if 3 lemons have 0 seeds, another 1 seed and another 10 seeds and 4 hybrids come out with Poncirus (which was used to pollinate the lemon flower) then the percentage is 36.36%, but only with 1 lemon would it give me any percentage . This was a real experience when I made my hybrid.
Another topic that helped me a lot was "removing all the competition", that led me to go from 25 pollinations and obtain only 1 fruit, to 10 pollinations and obtain 6 fruits (in Nagami).
In other words, you must remove each flower that is not pollinated by you. In kumquat, it is very difficult and laborious because it continues to bloom and you have to remove each new flower that wants to come out. It is an everyday job.
Also in Poncirus the flower is rare, you have to time it. Kumquat can release pollen when the flower is closed (hours before opening), while Poncirus opens its flower completely and the stamens are green... When they start to turn orange but still do not release pollen, that is the right time to pollinate. Maybe some of this will help you, maybe the Poncirus that pollinated, of 20 flowers only 4 did not fall.
That seems like excellent advice which I haven't thought of and I will definitely try to remove "competing" flowers. Also, very good pictures. Are those all from flying dragon?
