Maybe it's important, if any of you have possibly hybrid seeds, to distribute them to others, especially those who may live in a bit warmer climates.
Of course the growing and propagating part of breeding cold hardy citrus would be easier in warmer climates, yet there's little interest in trying to breed cold hardy citrus among people who live in climates where normal citrus can easily be grown.
I suppose the ideal breeding program would involve a partnership of some people living in colder climates and someone else living in a warmer climate willing to propagate the seeds, and then eventually send cuttings or plants back, where they can be grown and tested in the colder climates.
Also, if any of you have rarer cold hardy citrus varieties, when the plant fruits it would be good to distribute the seeds to other cold hardy citrus growers who are on a list.
