Whitefly (B. tabaci) resistant tomatoes are an answer to many whitefly induced problems and an important part of an integrated approach of pest management. In this assignment we will follow the steps a tomato researcher resp. breeder has to take to introduce resistance in commercial tomato cultivars during the breeding process. This is a conventional approach and no genetic modification (GM) is used. The breeder needs to take the following necessary steps:
Develop a reliable screening method for whitefly resistance
Search for the best donorplant with whitefly resistance in wild tomatoes that can be crossed with tomato
Making crosses between resistant wild tomato plants and susceptible cultivated tomato plants
Develop segregating populations
Linkage analysis using phenotyping and genotyping data
Application of the linked molecular markers in a breeding program to obtain new commercial varieties
