'Amalia': a medium-fruit-size, heat-tolerant tomato cultivar for tropical conditions.

摘要

Amalia is a released cultivar resulting from a tomato breeding programme that started 22 years ago at the Instituto Nacional de Ciencias Agricolas of Cuba. The objective of the programme was to develop tomato cultivars with medium-sized fruits, heat tolerance and early blight (caused by Alternaria solani) resistance. The pedigree involves crosses between lines followed by successive steps of selfing and selection. The parents of the first cross were 'Campbell-28' and 'INCA-3'. Amalia combines heat tolerance with early blight resistance and can be cultivated profitably in May through October, maintaining an excellent performance in wintertime (November-April), thus extending the tomato season for almost the whole year. Amalia may also be useful to tomato breeders as source for breeding heat-tolerant hybrids or improved inbred lines.
