Anyone know the 1st fertile interspecific hybrid? 1st fertile intergeneric hybrid? for plants?

I have been looking into the history of genetic modification. I located a source that stated that the 1st fertile interspecific hybrid was created in the 1700s and moreso, that the 1st fertile intergeneric cross was created in the 1920s. I found that the first artifical interspecific hybrid was created by Thomas Fairchild in 1719 (carnation x sweet williams), but I can't find any info on whether it was fertile. I noticed also that the first cereal hybrid was bred between wheat and rye - triticale - in 1876 by Wilson. As well, I noticed that the first case of hybrid vigor was observed in tobacco by Joseph K lreuter in the 1760s. I was guessing orchids, but their first interspecific cross was done in the early 1900s. I also came across mention of an interspecific cross in Darwin's Origin of Species, where W. Herbert crossed Crinum capense with C. revolutum to produce fertile hybrids, but this must have been in the 1850s. As to the 1st fertile intergeneric hybrid, I have no leads.

I believe part of your problem is that in so many species the first crosses were not documented. Or the crosses occurred in nature.

"The first recorded experiments date to 1825 as F. arborescens Χ F. macrostemma and F. arborescens X F. coccinea where the quality of the resultant plants was unrecorded.



Between 1835 and 1850 there was a tremendous influx to England of both hybrids and varieties, the majority of which have been lost."



For example in fuschias F. magellanica and F. fulgens appear to be the primary parents of traditional hybrid fuchsia plants, though perhaps up to10 other species may have been involved later. Without doing a direct sequence comparison between the species and all the hybrids we will not know.



Tangelo, a hybrid of a Mandarin orange and a pomelo or a grapefruit may have been developed in Asia about 3,500 years ago.
