Tomato Brown Rugose Fruit Virus (ToBRFV) Resistance or Tolerance Breeding Thread

[William Schlegel]

It seems that I have made 27 crosses and crosses with those crosses towards breeding in tolerance and resistance.

The following is the number in my tomato inventory a space then the cross, and another space and a brief note on what I think might segregate out of the cross. MMS of course standing for the MMS type which is a blue skinned yellow red marbled bicolor potato leaf.

283   MMM x Brown Rugose LA1375   MMS 286   Dwarf Gloria's Treat x Currants   BICOLOR 302   (MMM x Purple Zebra F1) x (MMM x LA1375)   STRIPES, Purple/Chocolate/black 303   (MMM x PH5 LB pimp) x (MMM x LA1375)   MMS 304   Fisher's Earliest Paste x (MMM x LA1375)   LONG 305   Ida Gold x (MMM x LA1375)   YELLOW 306   (MMM x Sweet Cherriette) x (MMM x LA1375)   EARLY 314   Dwarf Eagle Smiley x (MMM x Brown Rugose LA1375)   TASTY Yellow 316   Wilford x (MMM x Brown Rugose LA1375)   MMS 317   Bison x (MMM x Brown Rugose LA1375)   MMS 320   MMS x (MMM x LA1375)   mms 331   MMM x (MMM x LA1375)   mms 355   (MMM x LA1375) x (MMM x galapagense X)   MMS Orange 366   Payette x (MMM x LA1375)   MMS 369   Hoosier Rose x (MMM x LA1375)   MMS 494   Galapagos Pear x 303?   pear 495   Dwarf Mocha's x MMS x MMR x 303?   yellow, blue, chocolate 496   MMR X DGT X Current   YELLOW BLUE 497   Puerto Cortes x 303?   MMS 498   MMR Dwarf x 303?   Yellow, Blue 499   Dwarf Moby's x 303?    Yellow, bLUE 500   Dwarf Johnson's Cherry x 303?   yELLOW bLUE 501   Mocha's x MMS x 303?   YELLOW, BLUE, chocolate 504   Glacier x 320 MMS x (MMM x LA1375)   MMS 508   366 x 358   MMS 511   (Dwarf Mocha's x MMS) x PI 390714 brown rugose true resistant pimp   Black 513   nodak early x 303?    early MMS thick walls?

My general goal with all these crosses was to hopefully preserve some of my favorite tomato genetics should we ever be hit hard by the virus. My hope is also that by making new crosses and thus preserving and selecting from more lines- that some of those resulting lines would have the resistance. I also hope to continue making new crosses with virus resistant material.
