Abstract: Two trials were conducted during the period October 1984 to May 1985, to identify AVRDC tomato varieties that can yield reasonably high when grown during the hot wet season (off-season) and/or cool season (in-season) of the tropical lowlands. A total of 30 varieties were evaluated. The results showed that four open pollinated varieties, i.e, CL5915 - 229D4 - 1 - 1 - 0, CL5915 - 229D4 - 1 - 5 - 0, CL5915 - 136D4 - 1 - 0 and CL5915 - 222D4 - 0 - 4 - 0: and two hybrids, i.e. PT913 and PTI600 out-yielded the Caraibe, the best of the currently grown varieties, The highest yield of 43.99 t ha-l came from CL5915 - 229D4 - 1 - 5 - 0. This yield was more than double of the Caraibe (19.15 t ha-1). Yield difference was due to differences in fruit size and number of fruit plant-1. ----- Durante el periodo entre Octubre de 1984 a Mayo de 1985, dos experimentos fueron llevados a cabo con el objeto de evaluar variedades de tomate del AVRDC, de alta producci6n, esto cuando estuviesen plantadas 0, durante la estacion calurosa y humeda (fuera de estacion) 0, durante la estacion templada (en estacion) de las zonas bajas tropic ales. Un total de 30 variedades fueron evaluadas. Los resultados mostraron que habian cuatro variedades de pollinacion de eruce, ejemplo: CL5915 - 229D4 - I - I - 0; CL5915 - 229D4 - I - 5 - 0, CL5915 - 136D4 - I - 0 y CL5915 - 222D4 - 0 - 4 - 0 Y dos variedades hibridas ejemplo: PT913 y PTl600, las cuales produjeron mas que la variedad Caraibe, la cu~1 es considerada como la mejor entre las que se plantan actualmente, La produccirin mas alta de la variedad CL5915 - 229D4 -I - 5 - 0, fue de 43.99 t ha! , Esta produccion fue mas del doble que la de la variedad Caraibe (19.15 t ha- 1 ). Las diferencias de rendimiento fueron debidas a Ulna variacion en el tamario del fruto y al rufrnero de frutos planta-1 .
