Tomato yellow leaf curl virus and root-knot nematodes cause diseases in tomato that can lead to heavy production losses. Resistance genes against both pathogens are available and used in breeding. Molecular markers for resistance gene alleles greatly enhance selection of resistant plants in breeding. In order to make marker-assisted selection for the most commonly used resistance genes in tomat...

In the present climate change scenario, controlling plant disease through exploitation of host plant resistance could contribute toward the sustainable crop production and global food security. In this respect, the identification of new sources of resistance and utilization of genetic diversity within the species may help in the generation of cultivars with improved disease resistance. Begomovi...

Whiteflies cause damages to many economically important agricultural crops because of their feeding habits and their begomovirus transmissions. The whitefly Bemisia tabaci is a genetically diverse group, which includes a large number of different biotypes (see Part I, Chapter 3). It is extremely prolific; a single female may lay approximately 400 eggs during her lifetime. Unfertilized eggs give...
