Whenever you look at the plant tag or seed packet of tomatoes, you may see a bunch of strange abbreviations. Those abbreviations indicate that the cultivar has been bred for specific disease resistance. Combinations of V, F, and N are the most important to look for, but try to choose cultivars bred for resistance to problems common in your geographical area. To help clarify what these abbreviations stands for, I developed this list:
- ASC = alternaria stem canker
- BC = bacterial canker
- BSK = bacterial speck
- BST = bacterial spot
- BW = bacterial wilt
- C1, C2, etc. = leaf mold
- CMV = cucumber mosaic virus
- CR
- EB = early blight
- F1, F2, etc. = fusarium wilt races
- FCRR = fusarium crown and root rot
- LB = late blight
- N = root-knot nematode
- PM = powdery mildew
- PVY = potato virus Y
- Si = silvering
- St = gray leaf spot
- TEV = tomato etch virus
- ToMV = tobacco mosaic virus
- ToMoV = tobacco mottle virus
- TW, TSWV = spotted wilt virus
- TYLC = tomato yellow leaf curl
- V = verticillium wilt
