TSWV Tomato spotted wilt virus
I am beginning this post due to a General Discussion Post on Spotted Wilt Varieties. As I seldom get to the other forum topics to even visit, therefore, I am hoping that this discussion where I am the moderator will help keep me involved in the direct issues.

================================= As a breeder of tomatoes I was surprised on how few of the TSWV resistant lines I have grown. Even fewer in my crossing programs. Not so many years ago, the general consensus hinted that there were no resistant lines available. The advanced work on developing the resistance has mushroomed the last few years, but not among heirloom growers, alas. The problem..... Most of the TSWV resitant tomato cultivars are not very tasty tomatoes. The list of TSWV resistant tomatoes to date.12-28-07 Sweet Cluster F1 Sebring Muriel Health Kick Cupid F1 Crista F1 BHN-685 BHN-640 BHN 555 BHN-444 Belle Rose Amelia VR F1 NC 0256 NC 032939 NC 0341 BHN 601 Quincy SVR 01408426 Topgun HMX800 HMX9800 HA-3074 HA-3371 WS 4062 Fla 925-2 Stevens Corrida Extremo DRW 7556 DRW 57-19 Kerala Kamuka Paradise Camel (HMX 4793) El Cano (XP 2508410) Bullet points about TSWV:
I would like to do more to help on this matter, but I've found that there is little support to someone like me to do this. My talk in Iowa earlier this year (2007) about introducing hybrid heirlooms with improved disease tolerance and other qualities left me with the impression that I was largely alone in this effort. I will try to access some of the lines with the TSWV resistance and/or if anyone sends me seed of those. I will try to breed these lines, hybrid or not, to test the single gene dominant trait (published) and to find marker genes associated with resistance. I have some heirloom lines that I will cross, but if others have suggestions on what heirlooms need to be crossed, let me know. Is the need veritable? Can the resistant heirloom/commercial hybrids be tested or first releases by 2009? Can true breeding lines of new TSWV heirlooms be released by 2012? What support structure can be implemented? Seed Venues? Who, What, Where,When, and How? The answers to the above questions could be totally affirmative, however there is this confessional: I have listened to many Inspirational talks by keynoters over the years. I fear that the audiences are somewhat inspired, but left unchallenged. I, unfortunately, am not the inspirational speaker, nor the challenger; if anything I am but a foot soldier in tomato breeding. The 2008 season is soon to started, let me know how I can help regarding TSWV. Tom Wagner |
