Evaluation of tomato germplasm for resistance to begomoviruses in Sanarate, GT: March 04

         Historical perspective for the achievements in Guatemala.  The two pictures below document the typical situation in a valley near Sanarate in 1994 and then the breeding plots in the same valley in 2004. 

 

 


1994

 Luis Mejia started started thinking about breeding for resistance, when he was on a Fullbright Fellowship at University of Wisconsin-Madison in 1996.  He saw a report in the TYLCV newsletter that Latterot from INRA in France had some germplasm with resistance to TYLCV.  Luis contact Laterrot who agreed to send him germplasm to evaluate.  Others also agreed, H. Czosnek and F. Vidavski from Hebrew University of Jerusalem; M. Lapidot from Volcani Center, Israel; P. Hanson, AVRDC; J. Scott, University of Florida. 

    


2004

This image illustrates the results of the selection and breeding program.  The field trial is nearly in the same spot as the field shown above, but 10 years later. 

F. Vidavski and J. Angel are looking at the fruit of a breeding line which has its source of resistance from the initial efforts of Czosnek and Vidavski.  They introgressed begomovirus resistance genes from L. hirsutum into L. esculentum in a breeding line called 902.
