Here is an answer I got from SouthernGardening.com regarding looking for TYLCV cultivars. I explained what I grew, and what I did in my garden. Their answer is once again controversial and likely to inflame debate. So that I'm not accused of making this response up, I'm including the authors name and email at the end of the post. Tell me what you think... Pete, South Florida, Zone 10 >> From what I've seen, heirloom tomatoes are unlikely to survive in Florida unless grown in a greenhouse. Unlike heirloom roses, which are around *because* they survived Florida's inhospitable conditions, heirloom tomatoes were largely abandoned because they couldn't do well here and were displaced by resistant cultivars. So, by all means, try only resistant varieties, and the more they're resistant to, the better. Check with your county's Extension office to find out which named cultivars they recommend and what they're resistant to.>> Jim Aikin Gainesville, FL Jim Aikin [jimaikin@southerngardening.com]
