If heirlooms were sensitive to disease they wouldn't be around. They are
not proven to be resistant to disease because it is not economically
feasible for someone to pay a university researcher to prove it. I would
rather grow heirlooms (and do) than hybrids because hybrids have their own
alleged sensitivities. "That cold night," or "those hot days"...any excuse
for poor performance, and I've heard them all.
You can;t save your own seeds from hybrids and replicate the desirable
tomato. Seed costs continue to rise and rise. What happens if a disease
wipes out the parent strains of the hybrids? You'd better hope some people
are growing heirlooms and saving seeds. Margaret
