Abstract: For over 15 years the INRA Antilles Guyane Plant Breeding Station in Guadeloupe and IRAT Antilles in Martinique have been working in cooperation on breeding tomato varieties adapted to the Caribbean. The main problems encountered were heat tolerance and disease resistance, especially to Bacterial Wilt caused by Pseuooraones solanacearum which prohibits growing of susceptible tomato lines in infested areas. The first step of this work was the introduction and screening of an extensive world collection. This resulted in the identification of some tropical and subtropical varieties suited for cultivation in certain situations in the French Antilles. TIle second step was to breed varieties better adapted to our conditions. This resulted in the release of lines resistant to P. solanacearum and/or heat tolerant. The last variety released, "Caraibe," which is both heat tolerant and resistant to P. solsneceerum, also carries resistance to Stemphylium solanae (Gray Leaf Spot) and Fusarium oxvsporum (Races 0 and O. Further breeding is needed to add root knot nematode resistance, Cladosporium fulvum (Leaf Mould) resistance, to improve fruit quality and to-diversify varietal types. ----- Por mas de quince aiios la Estacidn Guyana del Mejoramiento Genetico, INRA Antilles, en Martinfca, ha estado trabajando cooperativamente, con miras hacia un mejoramiento genetico de variedades de tomate adaptadas para el Caribe. Los principales problemas encontrados fueron: tolerancia al calor y resistencia a enfermedades, especialmente al Aiiublo Bacterial, causadas por Pseudomonas soteneceerum, 10 cual no permite el creciminento de tomate de Iineas susceptibles, en areas infestadas, La primera etapa del mencionado trabajo fue, la introducci.6n de y la selecci6n de una colleccion mundial muy extensa. Esto dio como resultado, la identificaci6n de algunas variedases tropicales y sub-tropicales aptas para el cultivo, en ciertas situaciones, en las Antillas Francesas. La segunda etapa ful, de mejorar geneticamente, variedades las cuales son mejor adaptadas a nuestro medio. Esto dlo como resultado el relevo de lineas resistentes a P. soteneceerum, y con 0 sin tolerancia al calor. La ultima variedad relevada, 'Caraibe', la cual es tolerante al calor y resistente a P. soieneceerum, tarnbien es resistente a 5 temphylium solanae (Mancha gris) y Fusarium oxvsporum (Raza 0 y I). Se necesita llevar a cabo un mejoramiento genetico adicional para, poder obtener resistencia al Nodulador, al Cladosporium fulvum (Moho), mejorar la calidad del fruto y diversificar los tipos varietales.
