Breeding tomatoes for the Caribbean
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 varie-tiesadapted 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.
