Depends on a stated purpose. IN line with your reasoning, you are
correct or heretofore, the chances of coming up with a superior apple are
about the same if selected from natural hybrids (seedlings of unknown
parents) vs deliberate selection of parents.
However, one must assume that the hybridization process (plant breeding
in general) will eventually teach us something!!! (Sorry, I can't give
justification---------war is still an ongoing and unique human activity!).
In a personal sense, THE foremost reason why I justified my involvement
in MAIA (look at Purdue's NewCrop Web site for more info---subtle spam!!) was
simply to use it as a vehicle to learning and/or education. Or, this effort
will get more folks involved and hopefully the simple process will be a tool
for horticulture learning and nondestructive activity for everyone including
Will we get new and better apples? Who knows. And that, in itself, may
not matter at all. You must keep in mind that there are reasons why
"everyone eats at McDonalds"!!!!
Specifically to the reference to my recommendation of crossing Sundowner
x GoldRush for southern areas. Given the know genetic packages, these two
collectively contain some of the best possibilities. Or, the simple
suggestion may inspire someone to do this, which may lend to educational
activity. Personally, I think Lady Williams x GoldRush may be a better
choice (LW requires even less chill and is more productive than Sundowner),
but LW pollen is not widely available.
Personally, I'd love to see folks down south (and everywhere) plant
seedlings of superior maternal parents of asian pear and observe them for
some 12-15 years.
Anyways, Kev, I'd not take my comments too seriously. After all, I am
an admitted KornFlake and luvin' it.
Ed, So. Indiana, heaven, etc.
