Colour me foolish... laboritories? I dunno; tinkering too much? Human
curiousity run amuck?
Canadian zone 5b, U.S. zone is apparently 4b
I'm just trying to find my way amongst the forest of diverse information.
Thanks to global warming it's bloody hot here!
Potato leaf plants have a thicker epidermis than regular leaf so theory is
they're more disease resistant/durable. Also, heirlooms have withstood the
test of time, their disappearance in the past was not like the dinosaurs but
because of modern breeding for durable fruits to ship to market.
As for TMV, less than 1% of the current tobacco has the disease.
True...kinda. Alot of the older heirlooms have some resistance to certain
diseases and little or none to others. Disease resistant hybrids were
created taking the desired traits of those heirlooms and combining them.
