Abstracts of Current Research
Methodologies for utilization of wild germplasm for crop improvement:
Crop plants contain only a small fraction of the genetic variation
present in their wild relatives. To use tomato wild species
for breeding and genetic studies we developed an introgression
line population of the wild species Lycopersicon pennellii
in the variety M82. The population is composed of 50 lines
each containing a single introgressed segment from the wild
species while between the lines there is complete representation
of the wild parent genome. This populations enabled fine mapping
of single Mendelian genes and their cloning. Field trials of
the lines resulted in mapping of QTLs affecting yield associated
traits; our objective is to clone these QTLs.
