Has anyone grown these varieties for TYLCV resistance

15 years ago

Our island is getting hit hard with ToYLCV this winter. We think we know why, but that's beside the point.

I need to start seed again if we are going to have any tomatoes this year at all. By the time I get them out, it will be warmer, and that will mean more whitefly and thrips.

I was only able to find three varieties available to home growers, that say they are ToYLCV resistant.

This one is from Totally Tomatoes:

"Champion 11 Hybrid Tomato(VFFNTA) If you love the ever popular Champion Hybrid then you're sure to become a fan of this variety. Features even more disease resistance while maintaining the same delicious flavor and timing. Delivers high yields of meaty, 6 to 7 oz. fruits. Also exhibits intermediate resistance to Yellow Leaf Curl Virus. "

These two are from Tomatoe Growers Supply:

"Margo (VFFT) Hybrid New for 2009 Shiney red 6oz tomatoes are juicy and flavorful, making them just right for slicing. Compact plants only grow to about 30 in tall while still offering great production. The disease resistance package includes tomato yellow leaf curl virus resistance, which is also helpful for gardeners in many areas. Margo provides perfect size, taste, and disease protection in a beautiful tomato. Determinate 70 days"

"Sun King (VFTA)Hybrid Now gardners can harvest big, rich-tasting tomatoes all the way until frost. From the beginning of the season until the end, deep red, smooth meaty fruit is extra large with well-balanced mild, sweet flavor. Good crack resistance, few seeds, and very little waste make these tomatoes great for slicing. Vigorous plants are resistant to Tomato Yellow Leaf Curl Virus, serious problem for some tomato gardeners. Determinate 75 days"

TGS says this about Champion II:

"Champion II (VFNT) Hybrid Especially bred as a luscious sandwich tomato...solid, meaty slices with just the right sweetness. High yields of large fruit bigger than Early Girl and earlier than Better Boy. Outstanding performer. Indeterminate 70 days"

TGS does not mention any resistance to TYLCV like TT does.

If you guys know anything about these varities - good or bad - please let me know. Other than Champion, I have never heard of the other two until now.

Thanks

Corrie,

I'm looking at my new 2009 Twilley Seed catalog and see something called PS 01522935 Hybrid: Midseason (av. 75 DTM) "Unique new disease package features resistance to the recently troublesome problem pathogen Tomato Yellow Leaf Curl, plus TSWV and 5 others (V1, F1&2, N, ASC, Gray Leaf Spot). Fruit set up firm across a wide range of conditions, with high proportion of large to extra large grades (8 - 12 oz). Vigorous determinate. Trials report wide adaptation with performance holding up in both dry and humid climates."

25 seeds: 2.60
250 seeds: 19.90

Bill, thank you a million times.

I'm going to give Twilley a call first thing in the morning, order those seed, and ask them if they have any others TYLCV resistant.

I have not been able to download their catalog on the internet in a long time, and had completely forgotten about them, and they are a great supplier.

Thanks again
Corrie

Has Anyone Grown and Eaten an Angel Red Pomegranate???
Q
Comments (26)
I just had another Angel Red. It was a big beautiful red fruit, but the flavor was lacking (and it was not as sweet as I remember it last time). It's hard to say whether this is indicative of the variety, since there are so many factors that can affect fruit quality and flavor. Maybe the fruit should have been left on the tree another 2 weeks to ripen. But on a more positive note, I found this review on TropicalFruitForum.com: "Parfianka is considered by many as being the best tasting but this year, my first year with fruits, the Angel Red tasted better than the Parfianka. The Angel Red was sweeter and had better sugar acid balance to my palate. The Parfianka tasted like a Wonderful with very soft seeds. This could be because my trees are so young but remember that everyone's palates are different." - posted by simon_grow, December 27, 2013 - From what I have read, Angel Red is not really an exceptional variety among pomegranates, but it is an exceptional variety among the pomegranates that are ready to harvest in September. Therein lies the appeal of Angel Red to commercial growers, it is an early-producing variety; it's better than any other pomegranate variety commercially available in September. ( "Market Watch: New Angel Red pomegranate debuts in Southern California ", Los Angeles Times, David Carp, September 24, 2010 ) Most people seem to be saying that 'Angel Red' tastes like 'Wonderful' but with softer seeds.

Has anyone grown Limbertwig apples in Ohio
Q
Comments (1)
I haven't grown Limbertwigs in OH (but don't see why they wouldn't do well). I do know that a semi-dwarf tree can still get fairly large, upwards of 16 feet or more. If I had it to do all over, I would have planted ALL dwarfs on a trellis. My 4 year old semi-dwarfs (on mm111) are already too large to properly maintain without an 8' ladder and long-handled pruners. Good luck with your trees. You can probably grow a couple varieties up there that I can't grow down here. Honeycrisp, Northern Spy apples and sweet cherries come to mind.

Has anyone grown Phalaenopsis "Orchid World"?
Q

Just to be clear, this isn't my Phalaenopsis, I thought that you needed a picture to perhaps ID the particular Phal I was talking about. I will be receiving MY phal in the next week, but since you asked I put up a picture in case you could go recognize it in your own or someone else's collection. I'm curious if this grows just like any other Phal or if it has particular care requirements so I can grow it to its' potential.

Has anyone else grown Park's Cherry Sweetie tomato
Q
Comments (8)
I grew Cherry Sweetie a couple of times. I did notice that some plants were decidedly sweeter than others, but I assumed that it had something to do with my soil conditions. This year, I'm growing Sweet Million. I would say the taste is indstinguishable from CS. The only difference is that SM's are more like a standard cherry in size while my CS's were a good bit smaller. Both are very productive and yummy!

Talked to Twilley this morning, they sold out of those seed in a hurry. Have more on order, and will probably be able to ship them in March.

I should have Champion II, Sun King, and Margo in from TGS this week.

Grew Sophya, SecuriTy and Champion II this past winter- all reported to have resistance to TYLC virus. I did spray with permethrin every 10 days until I had fruit set to hold white fly at bay. All varieties grew and yeilded well. Champion II is still bearing 6 months after planting and is over 8' tall. Liked the flavor of SecuriTy (acidic) and Champion II (sweet, good tomato flavor) better than Sophya which was rather bland. The prior winter all plants died from TYLC virus before bearing (can't remember the varieties that year). Would like to hear how varieties tried by others faired and tasted.

Corrie, this is off subject, but I'm going to ask anyway. When you plant tomatoes as late as you're going to, how do you get them to grow in the heat? Mine just sit there. They don't die, don't grow, nothing. I would love to have a fall harvest of some determinate paste varieties, but I'd have to set them out in late July/early August. It's very hot (95+ days, 80+ nights) and somewhat humid here then (monsoon season).

I know that you use aluminet shade cloth and insulate containers. Is that it?

Last year all my tomatoes got infected. I am growing champion II from seed this year. Did not use pesticide to keep white fly at bay (after all is not virus resistance developed to avoid using pesticide against white flies?). All champ II got the virus. Worthless

If you read the blurbs, it is only intermediate resistance, not immunity. You MUST protect the plants to some degree or they will always go down with TYLC.

There are some varieties available now that have more stacked resistance genes. Four genes are in current literature ty-1, ty-2, ty-3, and ty-4. Check the Florida breeding program for some details.

One of the new resistance mechanisms is plants that repel whiteflies. Combine this with some of the virus tolerance genes and we should have tomatoes that grow and produce regardless of whitefly presence.

The Florida breeding program is working on this but may be a few years away from highly resistant plants.

Has anyone grown these varieties for TYLCV resistance
