Abstract: With the goal of improving the yield of cabbages for commercial production in the low humid tropics, we screened for better-adapted varieties. The characteristics chosen were heat tolerance (good recovery, good heading), the resistance to Xanthomonas campestris and Ervlnia carotovora. Forty-one varieties were studied between 19B3 and 1988, in 10 trials. The varietal screening resulted in the following choices for the first quarter of the year (the best season): KK Cross, Express Cross 60, Leo No. 80, Guardian, Globe King, YR Summer 50, Utopia, Resist Drum Head, Mascotte, Conquistador, Autumn Hero, Globe Master. During the second quarter-year, attacks of the bacterial disease Ervinla carotovora limit the possibilities of cabbage cultivation in Martinique. ----- L' amélioration de la productivité du chou est réalisée par un meilleur choix variétal. Les critères retenue sont 1'adaptation à la chaleur (meilleur reprise, bonne pommaison) , la résistance à XanthomonaB campestris et le comportement vis-a-vis d'Ervinia carotovora. 41 variétés ont été étudiées entre 1983 et 1988 à travers 10 essais. Le choix est donné pour le premier trimestre (saison favorable): KK Cross, Express Cross 60, Léo No. 80, Guardian, Globe King, YR Summer 50, Utopia, Resist Drum Head, Mascotte, Conquistador, Autumn Hero, Globe Master, En deuxi6me trimestre, les attaques d" Erwinia carotovora limitent le développernent de la culture du chou cabus.
