Hopefully someone with knowledge on breeding and so on can explain this too me better...
Instead of the tulip tree being a heritage tree they decided it suited a outstanding tree for seeds instead.....
but that has now been a NO GO..........

what they are saying is that they do not want a tree that is self pollinating itself.....
there are about 1000 maybe 2000 flowers up the tree this year and only one seed pod fell down so that means that the rest of them have some viable seed in the pod but they are saying by cross pollinating you get more viable seeds as DO all plants they say especially even if the hybrids such as lilies they said in specific....

but since this is a species tree this does not make much sense to me
considering that a native species in lilies has a good percent of viable seeds in the pod right??
like thinking Regale
or do they just have so many viable seeds even if they are species plants??

The whole thing is more complicated than you think. Believe them, because they are correct. To put it simply: it's not that your seed is not viable, it's that cross pollenated seed is healthier.

eventually the plants grown from an inbred seed source may decline in viability, for example when Dawn Redwood (metasequoia glyptostroboides) was first discovered to not be extinct a small seed collection was made from which all the USA population of that tree came from, after a few generations seed viability became very poor, another collection was supposed to have been made in the 1990's to get a broader genetic base to produce trees from to solve that problem. So inbreeding can eventually cause problems down the line, in more ways than fertility. It can lead to increased susceptibility to diseases and a general decline in vigor.
In Western Oregon there are a few scattered populations of Ponderosa Pine, you cannot take a population from one area and plant the seed in another area and have them live to maturity, they will only get to be large enough to be difficult to remove when they die. The populations are inbred and cannot tolerate conditions outside of the area they evolved in. Another good reason to not have any of those horrid trees in you life.
