Several national tomato breeding projects began work on developing varieties resistant to bacterial wilt over 60 years ago and several varieties created in the 1950s, 1960s, 1970s and later on are still found as reference varieties in many recent publications dealing with the genetics of resistance. From the beginning there were many exchanges of resistant material between the breeding programs that are difficult to retrace because published information is scarce. As a consequence the source(s) of resistance of the reference varieties, and the relationships between these varieties are often unclear. This paper provides a synthesis of the relationships between the breeding carried out in Puerto Rico, the USA (North Carolina, Hawaii, Florida), Japan, the Philippines, the French West Indies, and Taiwan, the main sources of resistance that they used, as well as the parentage between the lines they created. The limits of the reliability of our results are explained. The information on the resistance of many bacterial wilt resistant lines to other vascular diseases is also summarized together with some other peculiarities, in order to provide a synthesis useful for breeding bacterial wilt resistant tomatoes and for further genetic studies of the resistance patterns
