Foreword Report of the Tomato Genetics Cooperative Number 60- December 2010 University of Florida Gulf Coast Research and Education Center 14625 County Road 672 Wimauma, FL 33598 USA The Tomato Genetics Cooperative, initiated in 1951, is a group of researchers who share and interest in tomato genetics, and who have organized informally for the purpose of exchanging information, germplasm, and genetic stocks. The Report of the Tomato Genetics Cooperative is published annually and contains reports of work in progress by members, announcements and updates on linkage maps and materials available. The research reports include work on diverse topics such as new traits or mutants isolated, new cultivars or germplasm developed, interspecific transfer of traits, studies of gene function or control or tissue culture. Relevant work on the Solanaceous species is encouraged as well. Paid memberships currently stand at approximately 94 (includes those paid in 2009 and beyond) from 16 countries. Cover: Design by Dolly Cummings. Bacterial wilt incited by Ralstonia solanacearum is a serious threat to tomato production in many humid tropical production regions. Breeding for resistance has been a challenge due to multiple strains of the bacterium, variable environmental effects on disease expression, largely unknown genetics for resistance, and linkage of resistance to small fruit size. Locating molecular markers tightly linked to resistance genes should be a boon to future breeding efforts and with the tomato genome now sequenced this research may advance much more rapidly than in the past. This years‟ feature article explores the major sources (“roots”) of bacterial wilt resistance and thereby sheds light on the relationships of genotypes that could be used in studies to locate molecular markers. Precision in the exact identification of sources is hampered by a lack of information or by conflicting information. Unfortunately some of the old sources are no longer available. If you read the article and have information that would help us improve the article please contact us. We live in an electronic age and if we get better information we will put it in the article and future versions may be better than the one published in December of 2010. If you have seed of a rare source line send it to us and we will see that it gets in a gene bank. Thanks for your help. 2
