Evaluation of tomato germplasm for resistance to geminiviruses in Sanarate, GT

         Luis Mejia, Universidad de San Carlos, Project leader

 

GF13 Breeding Line

Breeding line, GF13, was selected from a hybrid, FAVI 9, which was made by Drs. Favi Vidavski and Hanokh Czosnek, Hebrew University of Jerusalem.  The resistance was derived from L. hirsutum (Phytopathology 88:910-914).

 

GF13 in January 2003 26 days after transplanting at Sanarate, Guatemala.  No symptoms on plants. Comparison with commercial hybrid, Marina, which had symptoms on 100% of the plants.

 

  GF13 in mid-March 2003 about 78 days after transplant.  Extremely, mild symptoms were evident on plants.   Comparison with GC6, a line from Cuban cultivar HC7880, which had symptoms on 100% of the plants.

 

GF13 in early April 2003 about 97 days after transplanting.  Mild symptoms were evident.  Comparison with GC6, susceptible line from HC7880 (Cuban open pollinated cultivar).
